The case for energy loans: read our latest explainer
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 we have mentioned previously, New Zealand's electricity is much less renewable - and much more expensive - when there’s not enough water in our hydro lakes and we have to burn coal or gas in winter at times of high demand, like we did this year.
Rooftop solar is the cheapest form of electricity availlable to New Zealand households, because the price of the panels has declined so rapidly and the energy is generated where it is used. The price has declined rapidly, while grid electricity has risen and is expected to keep doing so (the red line is what customers are expected to pay for more expensive upgrades to the poles and wires).
Sunshine hours are, on average, 5% higher in a dry year compared to the average and 10% higher in April/May/June. More rooftop solar could help provide the electricity the country needs through winter, and also ensure we go into winter with higher lake levels.
Compared to most of our MPs, Scott Willis is a very early adopter. As the latest episode of our 'Political Power' series shows, the Green MP's home in Waitati has had solar panels on the roof since 2013 and he bought a Nissan Leaf in 2016. He runs a full suite of electric gardening gear - which can often be a powerful gateway drug after people see how well they perform - and recently upgraded to a BYD Atto3 with a 60kwH battery.

But Mike said the cherries were less about currying favour and more about opening a cross-party conversation on electrification. “I want it to not be a political hot potato, because I genuinely believe, no matter what side of politics you’re on, electrification is good for the country. From an energy sovereignty, an energy security, an economic and a climate perspective, everybody wins.”

We reckon a lot more of them should be electric - both for the benefit of those companies but also to seed the second-hand market - and that could be on the cards now because one of the major barriers to fleet EV uptake has been removed.
