'This car can...' Check out our new campaign
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.
A very cool 'floatovoltaics' project makes use of unproductive pond space and also helps those struggling with their energy bills; renewables push down the price of electricity to nothing (or less than nothing) in Scandinavia and South Australia and New Zealand has an opportunity to follow suit; France goes hard on electrification, while the UK builds better; Aussie truckies reckon electrification will take decades but much bigger electric machines are here now, including some from Volvo; hydrogen generators are an innovation we do not need; the Speight's brewery gets off the gas with a $7.2 million electric boiler; and a bit of 'solarcasm' demonstrates how going off-grid is now an option for some.

Now Business NZ has added its voice to the debate, suggesting that the $200 million set aside to help the oil and gas industry is instead used as loans to help businesses electrify. The rare call for support came after it released a report showing that the businesses reliant on gas were struggling with increasing prices and their closure would have a massive impact on jobs and the economy.
