Electric Avenue: 24th January

Some big switch energy this week as solar panels go vertical on farms (and on fences), induction disappears in fancy kitchens and celebrity chefs move towards the magnets, Counties Energy pushes a vision of the future that we can get behind, Bunnings spots a trend and launches a new range of EV charging products, and a brilliant game created to annoy asset managers investing in fossil fuels.

Don’t fence me in

New Zealander Bill Gallagher invented the electric fence, but cheap solar panels mean our electric fences are now even more useful. 

There’s plenty of excitement about agrivoltaics at the moment, with studies looking at how panels work with animals grazing underneath or how they affect crop and grass growth. In horticulture, there might be excessive shading, but there might be a solution to that, as reported by the New Scientist. 

As the story says: “Rapid reductions in the price of solar panels mean they are starting to appear in unexpected places, from balconies to motorway embankments. Now, researchers say they could play the role of hedgerows in farm fields, with double-facing solar panels generating power while acting as windbreaks for crops and livestock.”

Last year, the FT reported on a global glut of panels leading to a rise of solar fences in residential areas. 

“Why put up a fence when you can just put up a load of solar panels, even if they’re not aligned exactly to the sun?” says Martin Brough, head of climate research at BNP Paribas Exane. “Where the panels themselves are just incredibly cheap, the constraints become the installation costs and the sites . . . you get a bit of a DIY mentality.”

The future is magnetic

Anyone who has an induction cooktop usually raves about it. But invisible induction takes it up a notch.

As British chef and show host Matt Tebbutt explains in this video for TPB Tech, recent advancements let you cook directly on your benchtop. 

Samin Nosrat, the author of acclaimed cookbook Salt, Fat, Acid, Heat, is also an induction fan because there’s no carbon monoxide and other noxious chemicals being pumped into the kitchen from the gas stove, and it’s also much easier to clean, more precise and ultra powerful. 

”Anybody who’s ready to replace their range at this point, for any reason, should really strongly consider induction.”

She uses a Copper range, which we wrote about last year and comes complete with a battery so that no expensive wiring upgrades are required to get you off the gas and onto the magnets. 

In New Zealand, Headwaters Ecolodge in Glenorchy is a great example of commercial induction being used to create some top-quality food.

Conducting conduction

New technologies require us to change our thinking, our behaviour and our rules. And Counties Energy appears to be onboard, writing about how it hopes to become the “conductor of an orchestra, coordinating the generation, storage, distribution, and consumption of energy from multiple sources in this new system”.

Rewiring’s belief is that customers need to be seen as energy infrastructure and becoming what they call a distribution system operator (DSO) is all about using the network’s capability more efficiently, “so it can better flex and stretch to accommodate the energy load, keeping costs down for everyone, and supporting modern, renewable electricity sources.”

The past was one-way and centralised, from big power stations, down poles and wires and into homes and businesses. The future is more two-way and decentralised, with lots of homes providing energy into the system or changing their usage when it’s most needed. 

Some of the regulations need to change to enable this to happen and level the playing field, but different distribution companies are pushing ahead into this future. Counties Energy, which has already caught our attention with a charging station that uses old Leaf batteries and its solar powered grand prix cars in schools scheme, has been working to create a system where homes can “participate in a more resilient and multi-directional energy market through assets like EV chargers, solar panels, hot water cylinders and air conditioning systems”. 

“Less waste, better control for consumers, and improved grid resilience and reliability, are all expected outcomes of Counties Energy’s new DSO/DNO combined model. It’s a connected neighbourhood that brings to life a more resilient and sustainable energy future.”

Aisle have what they’re having

As one of the region’s biggest retailers, Bunnings can pick a trend and has a good understanding of what the people want. So it’s good news for New Zealanders - and for the energy transition - that it has just launched a new range of EV charging products. 

As its ads say, lowest prices are just the beginning, but those low prices likely to speed up the adoption rates and make investing in an EV and charging set-up even more of an economic slam dunk.

There are already plenty of electric tools on offer at Bunnings and more people are now aware that there is no sacrifice in performance, no fumes and less noise. We’re looking forward to seeing the solar panel and battery aisle opening up soon (as well as more information showing people how much more expensive it is to install gas appliances).

Putting the ass in asset management

It’s hard to be a family-run oil business these days. And it’s also quite hard to be an asset manager. Fortunately, you can test your skills with the game Asset Manager Quest, a game created by Serious People to “annoy fossil fuel financers”.
