Electric Avenue: 29 November

The electric bandwagon is speeding up, as EECA launches a clever cost-saving campaign showcasing the benefits of electric homes, Octopus opens the doors of New Zealand's first zero energy bills home this weekend, the silent solar revolution is spreading through the developed world, a glorious graph that shows energy economics winning over politics, Ford's new EV ute shows its towing prowess, and Mike Casey embraces his inner electric bogan.

Singing from the same songsheet

EECA has launched a clever new campaign with Grand Designs New Zealand host Tom Webster explaining why households should choose electric cooking, heating, hot water and driving when it's time to upgrade their machines - and how they can help bring their bills down with rooftop solar.

With more than half of all appliances in New Zealand homes over 10 years old, many of them will need to be replaced in the next few years, and the message in the campaign is not just to go for like-for-like (and not to wait for your ‘cold shower day’ and go with the first option an emergency tradie offers). 

The technology - from hot water heat pumps to electric vehicles and smart chargers - has developed quickly and come down in price considerably so it's worth making a plan for replacement and going electric. These machines last for decades so it's important to think ahead and, as this RNZ story detailed, dwindling gas supplies mean some suburbs could be cut off, which is why it's crucial we plan an orderly transition because, as we've said before, gas in homes is dumb.

Check out the campaign below and see what you could save with the calculator.

Down to zero

For a real life example of the rather endearing electric home in the EECA campaign, make sure you stop off for a visit at New Zealand’s first zero energy bills house in Auckland this weekend.

Built by Classic Builders, the home is “kitted out with solar panels and a battery [installed by Future Energy], where we can guarantee you’ll pay nothing for electricity* for five years. The best part is, it’s for sale!”

The open home is on Sunday 1 December from 11am - 1pm at 2/492 Richardson Road, Mt Roskill. And, as an added bonus, you’ll also have a zero coffee bill as they’re offering visitors a free cup. 

We showcased Octopus Energy’s zero energy bills scheme in the UK a while back, and it’s great to see New Zealand getting a turn. 

Octopus gets a few mentions in our weekly rundown, and for good reason. It’s pushing the electricity industry in the right direction with its own innovations and showing how customers will change their behaviour if the right incentives are in place. With this open home, it's proving that the right technologies employed in the right way can save money and create a more resilient energy system. More power to them.

Silent solar

Solar is often seen as a luxury good; something for the wealthy few to put on their fancy rooftops. In many cases, that’s true and those with the capital get to access the savings, which is why we are so vocal about the need for appropriate finance schemes so that everyone - no matter their income - can access the cost savings. But across the developing world, solar is becoming a necessity. 

As Bill McKibben writes in a piece called ‘Silent Solar’: “Solar panels have, over the last months, suddenly gotten so cheap that they’re now appearing in massive numbers across much of the developing world. Without waiting for what are often moribund utilities to do the job, business and home owners are getting on with electrifying their lives, and doing it cleanly.”

In Pakistan, electricity prices have risen dramatically as a result of the war in Ukraine and electricity consumption has dropped, but cheap solar panels have taken up the slack.

“In just six months, Pakistan imported solar capacity equivalent to 30% of its total electricity generation capacity - an absolutely staggering amount,” said researchers Azeem Azhar and Nathan Warren.  

Solar is also displacing noisy, dirty and expensive diesel generators that run wells and offering more certainty on prices. And those who can invest are able to pay off the panels quickly by selling back to the grid. 

“By the end of the year, Pakistan’s distributed solar system could be nearing half the capacity of its entire grid! This isn’t just growth; it’s a silent revolution in energy production."

Inevitable - and sensible

One of the beauties of solar, as the above story shows, is that it’s a modular technology. A few panels can go on a roof and feed into a home, or a few thousand panels can be set up as a solar farm and feed into the grid. Over in the US, Canary Media sent out a note to its readers suggesting there was still reason to be optimistic about the energy transition, despite ‘recent events’. 

“Renewable energy in the U.S. has grown steadily over the last 20 years. Look at this chart of wind and solar expansion — you’d be hard-pressed to pick out where a Democratic administration ends and a Republican administration begins.”

Solar and wind don’t need to be political. This is energy economics in action and economics tends to win out over politics in the end. 

Towing the line

One of the criticisms of EVs is that they can’t tow like their fossil fuel counterparts. Most EVs in New Zealand today are not designed for towing significant amounts, but a new breed of more powerful vehicles is starting to change this. 

Towing certainly does reduce the range of an EV, just as it decreases fuel efficiency, but by how much depends on the weight you’re towing and whether the car has been designed to tow. One test showed an Audi e-tron decreased its range by one third when towing a caravan, while a Tesla Model 3 towing a caravan reduced its range by 50%. 

Tesla showed just how powerful its Cybertruck was when it took on a Porsche 911 in a special drag race (although one YouTuber has questioned the results by going deep on the details). In Australia, the newly available Ford F-150 Lightning EV ute lined up against a Toyota Landcruiser 300 for a similar stunt. 

The new Lightning ute is definitely not cheap (although they’re not too far off what the petrol equivalent costs), but they are much cheaper to run. This is the thing we always need to drum home: electric machines typically cost more upfront but are so much better at using energy to do the same thing as fossil fuel machines. So if we can swap fuel for finance, we’ll all be better off. 

Electric bogan

When he’s not taking home trophies for transformational leadership or pushing for changes to the system that would help customers, Rewiring Aotearoa CEO Mike Casey loves being what’s referred to in the literature as an ‘electric bogan’. As this promo video for Forest Lodge Orchard’s cherry harvest shows, he’s pretty good at reverse burnouts in the Kona and the electric chainsaw (often known as a gateway drug to bigger electric machines) is still fun to rev up.  

If you want to see what EV reviewer Gavin Shoebridge thought of the orchard and the self-driving electric tractor, this is worth a watch. 

Casey is also close to getting his hands on a long-awaited electric Hilux. 

In typically generous Casey style, he signed off his post with: “Toyota New Zealand Limited happy to provide the plans if you want to scale up Electric Hilux conversions in NZ!”
