A big week in the long-running battle to turn EVs into batteries on wheels, researchers prove that using cheap solar during the day to heat the water is a good idea for customers and the grid, a solar map of New Zealand that offers lot more detail, tiny turbines (and tiny homes inside massive turbines) and a flood resistant EV.

The Post gives readers a rundown of the inaugural conference and expo Electrify Wairarapa, which hopes to "break people out of the status quo and explore new technology when making business and domestic decisions".

Wairarapa is the place to be this week, writes Rewiring Aotearoa's ecosystem lead Jay Salzke. The Electrify Wairarapa Conference and Expo is kicking off in Masterton on the 22nd-23rd November and anyone interested in learning more about the massive electrification opportunity in front of local businesses, farms, vineyards, orchards, schools, community centres and homes across the region should be there.

We're sparking joy this week with Saul Griffith's electric solar powered scooter, Australia and Texas hit major solar milestones, Coldplay creates a truly electric atmosphere, Mike Hosking's EV queries answered with a graph, Kia's new concept car, and Counties Energy teaches kids about solar by taking the grand prix to school.

Christian Judge, who is leading the charge in his region through Electrify Kāpiti, explains why trusted community members are so important when it comes to household electrification.

Our rooftops are largely designed to shelter us, writes Mike Casey in The Post. But they could be doing much more than that. So why is New Zealand's rooftop solar adoption low? And what can be done to speed it up?

A bumper crop of electric goodies this week, with Douglas Park school in Wairarapa impressing with its solar, a rare bright spot for the climate as the world continues to run on the sun, UC researchers get funding to push perovskite, the world's most sustainable snowmobile, an EV expo in Christchurch and a true electric tinkerer.

New Zealand's emissions have fallen for the past three years. That's positive, but Rohan MacMahon, a Partner and Co-founder of the Climate Venture Capital Fund, believes we need to push harder and fully embrace electrification.

Government's proposed changes will help bring down costs and rapidly accelerate the adoption of solar and batteries.

We're in the business of changing perspectives at Rewiring Aotearoa and this week's Electric Avenue is a doozy, with Octopus Energy showing that customers will change their behaviour if there's money to be made, Australian coal miners drive a Tesla and have their minds blown/changed, an engine lover's break up letter with diesel boats after experiencing Vessev's VS-9, the IEA's latest report offers a revealing comparison, the story of the 'genius solar plane that can fly forever', Rainn Wilson pleads with the powers that be to heed his warnings, and ad network Ogilvy gets a fossil fuel flogging.

A groundbreaking pilot to electrify 500 homes in the Illawarra region of NSW was announced in Australia recently after a two-year campaign led by the local community.

Put your tongue on that battery, folks, because there's a groundbreaking pilot project in Australia that offers a glimpse at an electric future, a Wairarapa marae with solar and batteries is helping improve resilience after emergencies, solar farms are proving resilient to major weather events, fossil fuel gardening gear is getting the chop, golf courses are going electric and there's another beautiful electric caravan to drool over.

We’ve got a focus on the flames in this edition of Electric Avenue, with Dunedin company Escea’s new electric (and holographic) fire, a battery induction stove that’s well-suited to the outdoors, some amazing electric fire trucks, the rise of all-electric stadia, why nuclear might be a good option (if you buy your own reactor) and battery prices drop by more than analysts expected. 

After the announcement of the Government's policy statement on electricity, Rewiring Aotearoa CEO Mike Casey explains why we need a level playing field for customers, a more efficient electricity system and the smallest possible investment in gas.

RNZ's Kathryn Ryan has talked to energy researchers who claim rising demand for electricity in summer (largely due to increasing air conditioning requirements and EVs) will have repercussions on lake levels come next winter. And while Transpower says the risks of an electricity supply shortage this year have eased, next winter's forecast is concerning. Irrigation is also a major user of electricity in summer in some regions. Solar is well-suited to both of these cases as the electricity is usually required during the day when the sun is out, so more solar at home and on our farms can provide a lot of what we need with less strain on the grid and at the lowest cost.

As David Hasselhoff almost sang, jump in my much cheaper and increasingly popular electric car and see why 96% of EV owners would buy a second one; the UK's last coal-fired electricity plant is switched off; the IEA's renewables report makes for good reading; a Rivian takes an unexpected trip down a river; and comedian Tim Robinson gives some helpful advice to climate change communicators.

Gather round the heat pump, children, as we explore the big benefits of battery recycling, how customers giving up control can help the grid, a radical new plan for electric transport in Queenstown, big trucks, big chargers and big electric ferries, and a look at just what has been captured when it comes to carbon capture.

Mike Casey learned about the difference between planting carbon-sucking trees and avoiding carbon-emitting diesel when he was setting up his Central Otago cherry orchard. As he writes in The Spinoff, seeing this laid out was something of an 'emissions epiphany' and showed he had good intentions but was focusing on the wrong thing. He believes "many New Zealanders are also focusing on the wrong thing and could do with an emissions epiphany of their own". Electrifying your car, cooktop, water heater and space heater and powering them with renewable energy from rooftop solar, home battery and the grid is likely to have the biggest impact on your emissions tally. And, by comparing these 'dinner table decisions' with return flights between Queenstown and Auckland, the piece shows that substitution is often more effective than sacrifice.

In this week's e-party, gas in homes is dumb and electric homes are not, a simple solution for those who need to charge their EVs on the street, the wooden winds of change are blowing, and more electric tractor news (this time from the 1920s).

Rewiring Aotearoa's Investing in Tomorrow report shined a light on the multi-billion dollar opportunity in front of New Zealand if we rapidly electrify our homes and cars. Danyl McLauchlan's latest column (paywalled) in The Listener examines what's stopping that opportunity from being realised (hint: incumbent interests and a profitable status quo being protected by industry lobbyists "swarming the Beehive like flies around a dead cat"). As he writes: "Eventually, someone will have to notice tens of billions of dollars lying on the ground, just waiting to be picked up – even if political expedience and ideological dogma are screaming at them to ignore it."

Dr. Rajeev Shah is the president of the Rockefeller Foundation and, as world leaders gather for the United Nations General Assembly, he argues that nothing matters more to individual well-being than energy, which is what leaders need to focus on. As he writes: "Electrifying the world could produce the largest development gains since the 1990s. Electrification is about more than progress for individuals; it makes the world safer and more secure. High energy prices are straining livelihoods at a moment when coups, migration and unrest are destabilizing regions. And because the countries where energy access is lowest are projected to produce as much as 75 percent of greenhouse gas emissions by 2050, connecting people there to clean energy can help prevent climate catastrophe for us all."

It's all about the batteries in this week's electrification whip around. Big ones, small ones (but not uncomfortable ones), we love them all and an Aussie legend has developed an affordable way to run our homes with our EVs, a US startup is electrifying school buses and using them to help the grid, Lincoln University rolls out a new electric tractor, Meridian's storage solution is set to power 60,000 homes at peak times (and the company is also set to give away $1.2 million for community electrification projects), and global solar installs continue to exceed industry expectations.

Farmers stand to save money, make money and reduce emissions by adopting electric technology and powering it with solar and batteries. But, as the story in Farmers Weekly says, one sticking point for farmers is that, at present, they can’t gain the full value from rooftop solar when they have multiple connection points on one farm. Rewiring Aotearoa has called on the Government to make some regulatory changes so t farms with multiple connection points are able to group them together for billing purposes and make the most of their solar generation across the business.

Let's raise the roof! 🏠🌞 Customers with solar and batteries need to be seen as a critical part of our 21st Century energy system and academics from Auckland University of Technology agree, pointing out that the 14 biggest rooftops in Auckland would be equivalent to New Zealand’s largest solar farm. The rooftops of 167 schools and supermarkets would provide the same amount of energy, albeit much closer to the point of consumption and that's why we're arguing for a more decentralised system.

Mike Casey talks to Ben Chapman-Smith about how Kiwi farmers can get started on their electric journey and move away from diesel-driven machinery, while also outlining a few requests for Minister of Agriculture Todd McClay that would make on-farm solar even more beneficial.

The rise (and savings) of hot water heat pumps, Fisher & Paykel creates a one-stop-electrification shop, thinking fast and slow on World EV Day, Tesla gets into the train game, Vessev's beautiful boat, Toyota's white elephant, and one positive aspect of keeping up with the Joneses.

If you've got questions about our recent report showing the almost $100 billion electrification opportunity in front of New Zealand, then Lou Aitken probably got the answers at the Investing in Tomorrow launch event. Check out the panel discussion with Dr Saul Griffith, Reserve Bank chief economist Paul Conway and Parliamentary Commissioner for the Environment chief economist Geoff Simmons.

Rewiring Aotearoa thinks customers need to be considered part of the energy infrastructure and three academics from AUT agree, arguing that a more decentralised system could play an important role in a more resilient system. As they say: "By focusing only on solar farms, we are using new technologies in an old-fashioned way, by centralising power generation in certain locations, in the hands of a few companies."

"The only way we can begin to hedge our businesses against higher spot prices is by beginning to generate our own electricity," says Mike Casey. Read about how he hopes to turn his energy bill into a revenue stream with the help of solar and batteries that can generate electricity cheaply, and store it to sell when it's expensive.

Mike Casey lays out Rewiring Aotearoa's argument for a regulatory change that would allow customers with solar and batteries to compete fairly with large generators, something we call symmetrical export tariffs. It's important to note that these are not subsidies or rebates. "They simply ensure customers get a true reflection of the value they provide to the electricity market. They are no more a rebate than the half-hourly prices in the wholesale market, paid to generators for their output ... The current pricing structure is compromising New Zealand’s delivery of a secure and affordable power system; it fails to recognise that peak demand could be reduced with the help of household batteries; it perpetuates the idea that we need to spend tens of billions to upgrade our poles and wires to cope with that peak demand; and it is stifling demand for solar and batteries among New Zealanders because their true value is not being accurately reflected in the price paid for export."

The recently announced Energy Competition Taskforce has announced "two packages of work that collectively aim to encourage investment in new generation, bolster competition and provide more opportunities for consumers to manage their own electricity use and costs" and said it is "serious about creating change". Of particular interest to Rewiring Aotearoa was the section about better rewarding customers to "encourage greater uptake of things like time-of-use pricing plans, rooftop solar and batteries, and demand response by industrial firms," as EA chair Anna Kominik said in a press release. This is positive and aligns with what we've been asking for and what we outlined in our symmetrical export tariffs paper, but it is important to note that these are not rebates. This is just cost-reflective two-way pricing that levels the playing field between small and large generators. As Rewiring Aotearoa CEO Mike Casey says: "To date, every home giving energy back has been getting a bad deal. We believe their contribution to the system should be accurately priced and, as we said when the taskforce was announced, we want a level playing field, not just a slightly less uneven playing field." Casey says this pricing also needs to be mandatory otherwise the EA risks further delay to keeping bills down and building a more secure and resilient energy system. "We talk about guaranteeing investment signals on the big end of town. How about the average Kiwi got some guaranteed investment signals that are fair?"

'New Zealand can't afford not to electrify,' says Q&A's Jack Tame in the introduction to a story about Rewiring Aotearoa's new paper Investing in Tomorrow. He talks to Dr Saul Griffith about the savings at a household level, the $29 million a day electrification opportunity for the country as a whole, the economic slam dunk of rooftop solar and why the Government should be looking to give favourable finance to customers who can become part of our energy infrastructure.

One News has covered the Investing in Tomorrow report, which shows that big household savings from electrification add up to big national savings. As Dr Saul Griffith says about the $29 million day that New Zealand could save if we swapped out fossil fuel machines for electric equivalents and ran them off renewable electricity from the grid, rooftop solar and batteries: "It's nice to be able to make the carrot that large because I think it focuses the policy mind on how to get there."

We've filled our electric boots this week with more good news for EV seekers as the upfront costs keep dropping, the EV that has been around the world about 50 times, grid-scale batteries are on the rise and the world's biggest one is equal to about 130 million laptop batteries, restaurants in New Orleans are being given solar panels to help the community out in case of hurricanes, and a spicy electricity-related letter to the editor.

Saul Griffith speaks to Bernard Hickey on When the Facts Change podcast about the new paper Investing in Tomorrow. As it summarises: "Saul Griffith helped change the world a couple of years ago when he and a couple of "tech bro" mates convinced Joe Biden to rewrite the Democrats’ Green New Deal and pitch it as an Inflation Reduction Act to rewire America’s economy with renewable energy. Saul makes a pitch for Aotearoa to do the same, but much cheaper and much faster, instead of the government’s current plan to spend $1 billion importing gas over the next couple of years. He presents Rewiring Aotearoa’s paper on The Electrification Opportunity, which estimates cheaper power costs worth $10.7 billion per year by 2040.

A cornucopia of electrification optimism this week, with Ubco inking a big deal in Australia, FTN Motion also getting set to head across the Tasman, Octopus Energy's founder Greg Jackson on the new champ in energy town, David Wallace-Wells looks at what we will do with all our 'free' solar power, and Germany shows how loosening up permits for renewables has led to a huge and rapid boost of energy supply.

Farmer's Weekly editor Bryan Gibson talks to Mike Casey on the InFocus podcast about paying back the capital on a recent solar investment in five years, the changes that need to be made to the 'braided river' that is our national grid to incentivise more farms to become power plants, and the strangeness of the current system that sees fossil fuels sent from Saudi Arabia, to Singapore and then onto boats and trucks, when we could be powering our electric farm machines directly from the farm.

As we've said before, it's not just us arguing for more rooftop solar. A number of academics are onboard and Kevin Trenberth, Distinguished Scholar at the National Center for Atmospheric Research in the US and honorary academic at the Faculty of Science, University of Auckland, is one of them. As he says: "Germany has about 20 percent less sunshine than New Zealand, but 3.7 million solar systems generating 61 gigawatts of power (12 percent of their total energy supply). In New Zealand, there is an estimated 200 MW from rooftop solar, and all solar (not just rooftop) provides under 1 percent of New Zealand’s power. A major reason for the very low uptake of solar in New Zealand is the absence of incentives and effectively, penalties against investing in it." We're doing our best to create incentives and remove penalties by pushing for symmetrical export tariffs, where a customer is paid the same amount for any electricity that is exported from the premises at peak times as they are charged for any power they consume at peak times. If we level the playing field, customers can become part of the energy system.

Following the launch of the Investing in Tomorrow report, Nine to Noon's Kathryn Ryan spoke to Dr Saul Griffith about the massive savings opportunity that electrification presents New Zealand households and the nation as a whole, the lessons we can learn from other markets and changes we need to make to our electricity system.

"You can actually now demonstrably show that for large sections of every economy in the world, it is now cost effective to solve climate change – and that's a pretty radical new idea," says Saul Griffith.

"The principle narrative of the last few decades – that we can’t afford to solve climate change – is just not true," Rewiring Aotearoa CEO Mike Casey tells Ellen Rykers for the Future Proof newsletter as the organisation launches a new report outlining the economic opportunity of electrification called Investing in Tomorrow.

August 28: Rewiring Aotearoa has welcomed the announcement of a taskforce to address issues in the electricity market but says the time for investigating is over and it is now time for action.

Alka Prasad digs into the numbers in the Investing in Tomorrow report and finds out how New Zealand could save $29 million per week just by electrifying our homes and cars.

"Combined, New Zealand homes and businesses are currently spending around $55 million every day or $20 billion per year on fossil fuels, most of which are imported," says Saul Griffith. "Approximately two-thirds of New Zealand’s total energy needs are met by burning these expensive fossil fuels. But this country is one of the first in the world to cross an ‘electrification tipping point’, where the cost of buying and financing electric machines is cheaper over the long run than using fossil fuels. That leads to savings for individual households and it could lead to huge savings for the country as a whole.”

New research from Rewiring Aotearoa shows electrification could save New Zealand households around $29 million per day by 2040 and massively reduce the country’s emissions.

We’re all about the win-win-wins at Rewiring Aotearoa. And, as Dr Saul Griffith says in this presentation, electrification promises to save every New Zealander money, greatly improve the country’s books, and slash our emissions. What’s not to love?

More news, views and hullaballoos from the world of electrification, with a big event next week spelling out the economic opportunity for New Zealand; red states embracing solar and coppers embracing EVs in the US; Norway getting close to 100% on EVs; hydrogen cars sucking; Europe looking to the sky to get off Russian gas; and exciting news for e-bike entrepreneurs and explorers.

Rewiring Aotearoa has been advocating strongly for rooftop solar, because it's the cheapest form of delivered electricity available to New Zealanders, unlocks a lot of the savings associated with household electrification and would help deal with dry years because there's more sun when it's not raining. So it's always nice when someone agrees with you and a piece by academics Stephen Poletti, Bruce Mountain and Geoff Bertram backs our argument up. As it says: "To alleviate the energy supply shortfalls primarily attributable to low rainfall, we suggest rapidly expanding cheap solar photovoltaics (PV), specifically rooftop solar for ordinary households. Our soon-to-be-published research suggests such capacity can be expanded quickly and cheaply... we encourage the energy minister to make the expansion of rooftop solar the top option for expanding the electricity supply and tackling the gentailer power that bedevils the market. He will almost certainly find it quicker, cheaper and more popular than importing gas.":

Our ERP2 submission outlines what we think needs to be done to improve the Government's plan to reach our climate targets, electrify the Aotearoa New Zealand economy and build a fairer future energy system for New Zealanders that saves people money and does not leave anyone behind.

Batteries in homes and businesses may seem individually small, but they could have a significant impact on the security and resilience of New Zealand’s power system. For example, 120,000 homes (or 5% of households in New Zealand) with a medium-sized battery could potentially reduce the peak electricity load by as much as our largest hydro power station, Manapouri. That’s why we’re asking the powers that be for something called symmetrical export tariffs so that customers with solar and batteries are paid fairly for their contribution, the payback time will be reduced and more people will have the confidence to invest in these technologies so the price of electricity can be reduced and we can keep the lights on in the event of an emergency.

Our hydro lakes are basically like big batteries and we need to save them for when they are most needed, says Mike Casey. Currently it's the job of coal to help keep this big battery charged during a dry year and that's expensive and polluting. But when it doesn't rain it shines and between April-August, sunshine hours are, on average, 5% higher in a dry year compared to the average. 

We're all charged up this week with some more big - and magical - machines; one of the best looking caravans we've ever seen (plus some EV towing info); how the big batteries in these big machines are starting to play a role in the energy system; a solar breakthrough that might allow us to put solar cells on our clothes, mobiles or cars; and if you liked the movie Don’t Look Up, you might be into a new play at Silo Theatre called Scenes From The Climate Era. 

One's also helluva cleaner, with the average solar install potentially stopping around one metric tonne of coal from being burned at Huntly, as Mike Casey outlines in his opinion piece about the current electricity situation on Newsroom NZ. Solar is by no means a silver bullet for our energy issues, but more of it on our homes, farms and businesses means we can potentially have our cake (keep electricity prices low for New Zealanders and reduce coal use) and eat it too (give customers with solar and batteries the ability to benefit if prices stay high). There will be benefits for everyone in New Zealand if more people own their power, rather than continuing to rent it. But we need to start thinking about customers as part of the infrastructure, something that the market has not been set up to handle.

The Government has released a document outlining how it plans to meet our emissions targets. However, as stated by many climate scientists and media outlets, the combination of policies proposed in the ERP2 document will not keep New Zealand on track for Net Zero 2050, nor will they enable us to meet our third emissions budget. We want as many New Zealanders as possible to make a submission on the plan and share their main areas of concern and where they see the biggest missed opportunities. This guide will run you through the submisson process, outline our main arguments and even give you an email template to tailor.

"Electricity prices are higher than ever - clean energy charity Rewiring Aotearoa boss Mike Casey wants to change the game with solar power."

There will be benefits for everyone in New Zealand if more people own their power, rather than continuing to rent it. But we need to start thinking about customers with solar and batteries as part of the infrastructure, something that the market has not been set up to handle. Roll on that world, says Mike Casey.

With high electricity prices in the news recently, Jamie Mackay talks to Mike Casey about the role solar can play in bringing prices down for households with panels on the roof - and all New Zealanders.

EVs cross a big tipping point in China and upfront costs are expected to keep falling this year; sales of gas hot water systems decline in New Zealand for the first time in ten years; 'why the solar industrial revolution is the biggest investment opportunity in history' and opens up some amazing possibilities; the many benefits of induction cooktops; and Australian comedian Tom Gleeson explains why big power companies might want to put some solar panels on their power stations.

In this week's best of, a report showing that batteries beat oil by a long way when it comes to mining, EV sales in New Zealand still growing (and sun is an excellent fuel in Africa), the amazing electric machines currently being built in China, a handy video explainer on the concept of useful energy, and a classic Nissan Leaf commercial that makes you think about the machines that still burn fossil fuel.

After Mike Casey spoke to almost 100 people in Masterton about the economic and environmental benefits of electrification, long-time councillor Chris Peterson wrote an opinion piece about Rewiring Aotearoa's realistic ‘what’s in it for me’ approach to achieving results, the success of the Electrifying Queenstown event and the momentum that's now building in the region for an Electrify Wairarapa campaign. As he writes: "No matter your political persuasion, one thing that seems to unite us is saving money so it has been encouraging to see genuine collaboration — reflecting, hopefully, a realisation that we are all in this climate crisis together and that electrifying the region means there is also something in it for the community." Where next?

A new electric dumper in Wellington and new electric buses in Christchurch, an energy hardship project with real world data, a novel scheme in some US resort towns that makes up for outdoor energy use, Rivian's very appealing new charging outpost and easily the best love song we've ever heard.

Earning a place on this week's electrification podium, Auckland's new electric bus hub (and Palmerston North's big electric bus investment), Germany's new law enshrining solar rights and how tenants can benefit from publicly-owned panels in Zurich, an Australian experiment shows how EVs could play a role during grid emergencies (and why we need smart charging to reduce stress on the grid), and the inside story of New York's first all-electric skyscraper.

IDTechEx’s new report Battery Markets in Construction, Agriculture and Mining (CAM) Machines 2024-2034 shows CAM machines require a diverse range of battery solutions to cater to their individual needs, especially in agriculture such as tractors. Senior technology analyst Dr James Jeffs has looked at the different use cases and where they work best and the report shows battery demand for off-highway industries will be worth $8 billion by 2034. Rewiring Aotearoa chief executive Mike Casey gets a mention after his orchard introduced the Monarch electric tractor to the country, where it performs well for low-energy tasks like mowing.

The cup runneth over with good electrification news and this week's selection features EVs becoming cheaper than fossil cars in China, a promising peer-to-peer electricity sharing scheme on Aotea / Great Barrier Island, massive growth in renewable generation (and massive opportunity for New Zealand to become the Saudi Arabia of renewable electricity), Energy Mad reaches a milestone, and a special electric toy for the snow lovers.

"Mike Casey is a 'nerd' (of his own admission) in the world of electrification, he's blazing the trial right out front showing the rest of us what can be done and he's then very kindly sharing all his knowledge so we can learn and uptake as it suits our businesses. This is an exciting conversation that really ignited the flame of opportunity and how farming can be a solution to the country's energy issues!"

“What I get a lot is people talk about electric vehicles and what they say with electric vehicles is that they’re great for people in the city, but they’re not great for the people in the country,” Casey told the 2024 National Renewables in Agriculture Conference in Queensland. “And I always have to remind them that that couldn’t actually be further from the truth. Literally, the more [kilometres] you drive, the better off you are driving an electric vehicle ... If charging purely from the grid it costs us around $9 for a full charge, however with our solar and battery array we are expecting the cost to be closer to $2 a charge and are currently collecting the data to verify this ... One of the most remarkable things we now see in New Zealand is the number of farmers that are adopting electric vehicles because they’re starting to realise that per kilometre cost [of fuelling them is] significantly less than [petrol or diesel]."

It's pretty rare for someone to be invited back to the E Tipu Agri Summit two years in a row, but Mike Casey has plenty to talk about. Rewiring Aotearoa's Electric Farms paper proved there are similar benefits for the rural sector if we can turn farms into power plants and, as he says - and as he has shown on his own cherry orchard - New Zealand’s farmers could reduce their operational costs by going electric and generating a lot of their own electricity through mid-scale solar and battery systems. And they can also make money by feeding electricity back into the grid at times of high demand. “Whether in the home or on the farm, electrification is a real win-win. It’s not just the right environmental decision anymore, it’s the right economic decision. It’s a no-brainer. We just have to figure out how to make it easy.”

Queenstown, Wānaka and the surrounding region have committed to one of the world’s most ambitious climate targets and pledged to create a carbon-zero visitor economy by 2030. It’s great to have a bold target to aim for but, as renowned electricity lover Thomas Edison said, vision without execution is just hallucination – and right now, the region is a long way off track and lagging behind a number of other places. So how can the region go from talking to walking? It basically all boils down to this: everything that can be electrified needs to be electrified - and quickly. Read Mike Casey's full opinion piece on Newsroom.

Another great piece from RNZ's Eloise Gibson about our mixed rankings in the global EV charging stakes and the need to lift our game as EVs become more popular (globally, nearly one in five cars sold in 2023 was electric, a 35 percent year-on-year increase). The government promised 10,000 more public chargers by 2030 and $257 million in funding has been allocated to that goal. At this stage, it's not clear where that money will be spent, but one option that isn't explored in the story is the potential to make use of our 50,000 farms. Farmers investing in mid-scale solar and battery systems could not only power their own machines much more affordably and earn money for sending electricity back to the grid at peak times, but they could also become part of an extensive national charging network and create another new revenue stream. Farms are usually very close to the medium voltage networks, meaning they can scale up renewable systems without physical constraints or undue overloading risks to the distribution networks.

On this week's e-highlight reel, electricity generating windows from across the Tasman, the role community-owned microgrids can play in regional areas, the rise of electric boats, and how heat pumps save money and reduce emissions.

Across the world, farmers and machinery producers are stepping up to the challenge of reducing greenhouse gas emissions by electrifying essential equipment and exploring alternative fuels ... In New Zeland's Otago, cherry producer Mike Casey has been running a 6-hectare orchard without using any fossil fuels. Last year, it produced 80 tonnes of cherries for local and export markets. His fleet of 21 electric machines includes prototypes and traditional vehicles that have been converted to electric. "I never envisioned us going fully electric; I was just sort of thinking there will be some things that we can do to cut out diesel and cut our emissions," he said. "But what actually happened is we discovered we'd save about $40,000 a year of energy costs on our farm."

New Zealand is going to need a lot more electricity as homes and businesses swap out fossil fuel machines for much more efficient electric versions. MBIE has just released a report showing a range of different scenarios and under favourable economic conditions the demand for electricity could rise by 81 percent by 2050. Where we get all that extra electricity from is an important strategic question for New Zealand and the report says wind and solar will be the "least cost" way to meet this demand. At Rewiring Aotearoa, we believe a lot of the extra electricity we need could come from rooftop solar and because it is produced where it is used it is the cheapest form of delivered electricity New Zealanders can get. Batteries are also dropping in price and rooftop solar and battery combinations can reduce peak loads while saving on energy bills. This is vital context for how we choose to build out the energy system to be low cost and highly resilient.

On this week's electrification highlight reel, Contact Energy's new grid-scale battery project with Tesla, how the really big machine manufacturers are going electric, solar power reaches a big audience - and a big milestone - and a succinct summary of the efficiency of electric machines.

New Zealanders sometimes need endorsement from overseas before we realise we've got something special and the Aussies seem to be picking up up what Mike Casey is putting down. Following a keynote presentation at an agricultural conference in Perth, ABC's RN Drive show spoke to Mike about his all-electric orchard.

The Guardian Australia's Aston Brown looks at the promise of electric technology in the agricultural sector as well as some of the existing barriers to update and talks to Mike Casey about the opportunities that already exist in horticulture and viticulture. He also talks to Terry Krieg, the co-founder of Linttas Electric Company, who is developing a semi-autonomous combine harvester that claims to reduce fuel use by a third. But it's not just about reducing carbon emissions and costs, says Prof. Ray Willis, managing director of Future Smart Strategies. “It’s about redesigning the vehicle for the first time in 100 years. If you make it electric, inevitably it turns out to be better, more durable, more reliable.”

Rewiring Aotearoa CEO Mike Casey was invited to be the keynote speaker at AgZero 2030 conference in Perth recently, where he spoke about the opportunity in front of Australian farmers to do as he has done and electrify the machines on their farms and produce as much of the energy required to run them via rooftop solar - with battery storage offering another potential revenue stream. Not only does this save farmers money, it drastically reduces emissions through diesel use and, as the Countryman reported Casey as saying, "when everyone is winning, you don't need to fight".

The Otago Daily Times and The South Today covered the inaugural Electrify Queenstown conference at Millbrook Resort yesterday. Destination Queenstown chief executive Mat Woods said the event was to show "the benefits of electrification, and what businesses can electrify such as vehicles, heating and cooking methods" and there was a huge amount of interest from the business community. "It was important to build an understanding that when things need to be replaced, replacing them with electric alternatives are not only better for the planet, but can also be cheaper, and more reliable ... Realistically we expected 50 people to turn up, but we had to cap attendance for the morning’s panel at 150 people." Rewiring Aotearoa's Mike Casey was the keynote speaker, and his electric tractor even provided heating for the tradeshow in the marquee.

Rewiring Aotearoa was proud to be part of the inaugural Electrifying Queenstown event at Millbrook alongside more than 150 members of the local business community. DQ boss Mat Woods told Mountain Scene the idea for the event was sparked by the Electric Homes report about New Zealand becoming one of the first countries in the world to reach the ‘‘tipping point’’ and there's a positive peer pressure in the Southern Lakes air as the region attempts to create a carbon zero visitor economy by 2030. To reach that goal it will have to, as Mike Casey said at the event, electrify everything that can be electrified - and quickly. As Kinloch Wilderness Lodge's Toni Glover said, the best way to do that is 'just start'. Kudos to Destination Queenstown, the Queenstown Business Chamber and Aurora for making it happen. We'd love to see more events like this right across the country so we can share the economic and environmental opportunities of electrification to more Kiwi businesses. Where next?

This week on our electrification compendium, the country's coolest coffee delivery van, potentially the country's coolest truck, a new report with lots of amazing graphs on the transition to clean energy, how EVs should be seen as batteries on wheels and Climate Town's explanation of the dirty tricks the gas industry has used to keep us hooked up.

Consumer NZ's Powerswitch has been a great resource for customers looking to save money by changing providers. But the latest issue of its magazine is focused on the money (and emissions) Kiwis can save if they change their energy source from fossil fuels to electricity - and how there are even more savings on the table if you invest in solar panels. Consumer used a lot of the data created in Rewiring Aotearoa and EECA's Electric Homes report, and there are some handy tips in there for anyone thinking about upgrading their gas appliances or petrol vehicles.

Rewiring Aotearoa's Mike Casey has plenty of fans, but the electric ones on his orchard are definitely the biggest. EECA's Technology Demonstration Fund helped Forest Lodge import and install two electric frost fighting fans in 2020 and, as the case study says, "the company has saved thousands on energy bills and significantly reduced its carbon emissions. These successes have been achieved without sacrificing frost-fighting performance". You might not need your own frost fighting fans, but electric equivalents - from hot water heat pumps to electric vehicles - are now cheaper to run and better for the environment.

Jamie Mackay, who was recently made an Officer of the New Zealand Order of Merit for services to broadcasting and the rural community, says he has "a special thing going" with Rewiring Aotearoa CEO Mike Casey and admires the way he's driving innovation in the rural sector. Direct from Fieldays, he speaks with Casey about the practicalities of electric machines on different farms, and the new hybrid (and, soon enough, electric) utes.

From Fieldays, Rural Exchange speaks with Mike Casey about his presentation to kiwifruit growers at the Zespri tent ("it's all about how we save $40,000 a year on energy costs"), and how his orchard is showing other farmers what's possible.

Rural Roundup's Andy Thompson reminisces about his recent trip to Forest Lodge where he powered his radio station with the electric tractor, how to the reduce input costs through electrification and why solar is a gateway drug for more electric machines. "Farms are businesses and people run businesses in different ways. The whole idea is to show them what I've done and they can choose whether or not they want to adopt them. It's their business."

Electrification is our jam at Rewiring Aotearoa. And Electric Avenue is where we spread it. This week, reducing costs and connecting the community through solar panels and batteries at marae, the electrification excitement brewing in the rural sector, why solar roofs might take over from solar panels, how your first EV could be the last car you ever need, and how the best new car could be an old car.

Speaking from Fieldays, one of the country's biggest agricultural shindigs, Mike Casey speaks with RNZ's Charlotte Ryan about the excitement he's seeing from farmers about the benefits of electrification, the difference between solar on farms and solar farms, and the notoriety that comes from being on Country Calendar.

Rewiring Aotearoa's Mike Casey writes in Newsroom about the Commerce Commission's recent draft decision on how much the electricity distribution businesses can spend in the next few years. "This $1.3 billion saving is actually a win for consumers and a step in the right direction for the energy sector. While the bills are still going up by 74 percent over the next five years, they’re not going up by as much as they could have. And if the rules change, households, farms and businesses with solar and batteries can reduce their energy bills even further."

RNZ's Eloise Gibson has taken another look at the energy sector and found there are lessons to be learned from Australia, where around one third of homes have rooftop solar. In New Zealand, the number is a lot lower, but it's growing quickly and that's largely because it makes economic sense over the long term, especially if you've electrified your appliances and vehicles. Batteries and solar combos are also becoming more common and every home with a battery basically removes themselves from the peak period. "But Mike Casey of clean energy charity Rewiring Aotearoa said battery prices were falling quickly, and combined solar and battery systems were now the cheapest source of energy available to households - even including the upfront cost of buying the equipment ... Casey said if households had better access to low-cost loans, they could buy household batteries themselves and take pressure off electricity generators by using their own power in times of shortage. They could also sell their surplus to others, taking more pressure off the grid when supply is tight."

Drive Electric's board chair Kristen Corson outlines in Newsroom how new EVs and smart technology can do much more than just get us from A to B and could instead play a role in the energy system. As she says: "Next time you consider the potential of an EV in your garage, reframe it as a battery on wheels that can power your house and your business. This perspective reveals a whole new set of benefits beyond that of a car."

Rewiring Aotearoa's CEO Mike Casey explains the thinking behind a recent Commerce Commission decision, the gap it opens up for customer generation, storage and smart demand management technology, and the role the Electricity Authority needs to play to speed up adoption.

Welcome to the first instalment of our weekly trip down Electric Avenue, where the Rewiring Aotearoa team shares the good, the bad and the ugly (but mostly the good) from the world of electrification.

Rakiura / Stewart Island faces the highest electricity prices in New Zealand. Successive governments have funded report after report and numerous fly-in visits by Ministers have failed to change this situation for the local community. Rewiring Aotearoa believes the opportunity is to harness existing solar and battery technology to deliver significant cost-of-living savings and reduced emissions at scale via electrification on Stewart Island right now. With financed solar and batteries, electricity usage costs for residents could be halved without delay. Rewiring Aotearoa has been engaging with the local community, who have been sending us their power bills. On Saturday 27th April some of the Rewiring team visited Stewart Island (including Mike Rewi who has strong whakapapa to Stewart Island). What we are hearing from this community is many locals fear the proposals and the likely “preferred option” will be focused on replacing current diesel generators, not on reducing the cost of energy for consumers. Our proposal outlines Rewiring Aotearoa’s pitch for an alternative approach to develop a community-led energy solution for the Island.

RNZ's Eloise Gibson looked into the question of whether gas or electric appliances are cheaper and the evidence, as outlined in Rewiring Aotearoa's Electric Homes report, is pretty clear: even with the upfront costs of replacement and finance, running electric hot water, electric heating and electric cooking is much cheaper - and less toxic - than using fossil gas and it's cheaper still if you've got rooftop solar and batteries. It makes no economic sense for new homes to connect to gas in New Zealand and if your old gas appliance breaks down, it pays to make your next purchasing electric. "Compared with using piped gas heating, hot water, and cooking, a fully electric home could save almost $11,000 over 15 years for upfront costs and energy bills, the study found. Compared with using bottled LPG for heating, hot water, and cooking, a fully electric home could save almost $20,000 over the same period."

"Mike is probably the most public face for advocating for decarbonisation through electrification in New Zealand, and someone who is demonstrating outstanding leadership."

New Zealand farmers are renowned for their ability to produce things like lamb, beef and dairy, but there's a new product they're moving into: renewable electricity. A new report by energy transition charity Rewiring Aotearoa says the benefits to farmers of installing solar and battery systems include cheaper power, resilience to outages and being able to make money from selling electricity back to the grid. Maniatoto farmer Becks Smith said installing solar to power her irrigation systems is the logical next step for the farm business. "We're actually really good at producing off solar power, that's what we do with our grass every day," she told Newshub. Smith is planning to install solar to generate electricity on farm to run her irrigation pumps during summer, while in winter when the pump is turned off, she can still generate electricity and sell it back to the grid. She said it improves business and community resilience. "Farms have the opportunity to be local electricity hubs to supply into local networks. Should the infrastructure be damaged in a natural disaster, we have the ability to support our communities."

Queenstown Lakes’ commitment to a carbon-zero visitor economy will be brought to life for business owners and tourism operators at the region’s inaugural Electrifying Queenstown business summit next month. A collaboration between Destination Queenstown and Queenstown Business Chamber of Commerce, the initiative is powered by Aurora Energy, inviting local businesses to unlock the economic benefits of electrification, saving on costs and growing their business while decarbonising. "One of the most effective ways to decarbonise is by going electric. We’re excited to have experts joining Electrifying Queenstown to share knowledge and practical ideas to support the tourism and business community to shift to a sustainable future,” says Destination Queenstown Chief Executive Mat Woods.

What if you could arrange a half-day in the debating chamber when I could bring a group we’re calling the “Coalition of the Willing” to share constructive, economic solutions around the opportunities climate change and sustainability offer to Aotearoa New Zealand? Opportunities that could significantly lift our GDP, reduce billion-dollar infrastructure costs, create high-value jobs and maximise returns from our forestry and geothermal assets. 1. ReWiring Aotearoa (Mike Casey and team): Current strategy involves spending billions on infrastructure to move electricity from fast-tracked wind and solar farms, potentially doubling household costs. Casey’s fossil-fuel free, fully electric orchard in Central Otago shows how rooftop solar panels and batteries can deliver power directly to homes and businesses at a fraction of the cost, building energy resilience. The importance of this was highlighted this month. As we faced those potential power cuts, Casey’s farm actually delivered excess electricity back to the grid. While the farm uses 900 per cent more electricity than before it was electrified, most of that is self-generated or stored off the grid during off-peak times. Electricity is sold back during peak times. The annual saving on diesel is $40,000 a year. Imagine every farm in the country working like that.

Listen to Rewiring Aotearoa CEO Mike Casey speak about the Electric Farms paper from 4.38.

The New Zealand Green Building Council's new report 'Closing the Gap' shows that improving buildings could save New Zealand almost $40 billion and slash emissions. "Improving the standard of new buildings and electrification are no-brainers. The sooner we get started, the more emissions we’ll avoid and the more money Kiwis, businesses and farmers will save," says Rewiring Aotearoa CEO Mike Casey. Andrew Eagles, NZGBC chief executive says: "As New Zealand is bound by law and international trade agreements to reduce our emissions in line with the Paris Agreement, our buildings are a key lever." Actions explored in the report include: Staggered improvements to the building code, requiring new buildings to measuring operational and upfront carbon emissions at consenting stage from 2025, a 20% reduction in both upfront and operational emissions by 2028, 40% reduction in upfront carbon emissions and near zero energy in operation by 20230, and a 60% reduction in upfront carbon emissions and near zero energy in operation by 2034. Require all homes put up for sale or rent to have an Energy Performance Certificates by 2028, and all office buildings over 1,000sqm put up for sale or lease to have a NABERSNZ certificate from 2026. Phase out of fossil gas in homes and commercial buildings. Suggested actions include expand the Warmer Kiwi Homes programme to subsidise electrification of home heating from 2027, converting 25,000 homes a year. End new residential fossil gas connections from 2026. Implement a concerted programme, building on the successful replacement of coal boilers in schools and hospitals, to subsidise 10% of commercial buildings per year from 2026 to electrify.

[At 2 mins] Meanwhile plenty of Kiwis are taking energy security into their own hands, like retired chartered accountant Mike Campbell, who's moving into a retirement village where he's installed solar panels [and a battery]. "I'm producing more energy than I can actually use, even though I've got an electric car, and it goes off to the grid and it feeds somebody else." He would love to see the Government help young people install solar and battery systems. "They can help young people to reduce their power bills by a lot of money."
