RNZ reports on the changes announced by Ministers SImon Watts and Chris Penk that aim to increase the uptake of residential rooftop solar. Rewiring Aotearoa's Mike Casey said the changes to voltage limit would mean more generation, "which is exactly what New Zealand needs… for households in Australia, the average size for solar systems is about 10kWh. In New Zealand it's 5 or 6kWh because solar installations are being built to the size people are allowed to export. This allows for higher levels of solar panels to be on homes. It makes larger systems more economical. When you finance solar panels on your mortgage it probably costs you 13c per kWh - there are many retailers out there buying power off you at more than 13 per kWh. So every piece of power that you don't use in your home that goes back to the grid is actually still in the economic best interest of the household."
He said the more solar that was generated on the rooftops of New Zealand, the more it backed up the hydro system and meant it could be used more as a battery.
"It's a massive win for energy security."
How the sun led to higher salaries for teachers in the US and why this should be happening here, too; how "the once-rigid link between economic growth and carbon emissions is breaking across the vast majority of the world" as electrification gives more countries a productivity boost (and how that would allow New Zealand to keep embracing our long, languid summer break); solar continues to weather storms and provide 'free resilience'; Dunedin laundry company Preens goes electric and saves over 300 utes worth of emissions; the company that wants you to drink diesel exhaust; and a wonderful rundown of the Kill Bills tour - and the national electrification opportunity - from one of the tour sponsors.

Kirsty Johnston talks to Rainbow Nurseries about how it made the switch with help from a grant, and others who are unsure they will be able to keep getting gas. As one busines owner said: "We never considered the risk to the business of not actually having natural gas," one participant said. "We always expect that the price could fluctuate… But we never anticipated maybe having no gas coming from the pipeline." There are ways for the Government to help. And there is a huge amount of new renewable electricity coming on stream, so there won't be a shortage of electrons.

As he writes: "Gas in Auckland is formally past its peak in the latest forecasts from Vector, the city’s only gas distribution business, with new connections set to fall to zero in three years ... From 2029, there would be no new residential or commercial connections – with new industrial connections projected to have already ceased this year."
