The idea of sharing excess energy with your community has long been a dream of solar and battery enthusiasts and that idea is starting to blossom. Microgrids have been proven to work in remote Australian regions; some marae in New Zealand are helping to reduce bills for people in their communities; Kāinga Ora has successfully tested the concept of solar sharing in social housing; and Bright Spark Tama Toki is attempting to bring the idea to life on his home island of Aotea / Great Barrier.
Aotea has no power grid, but what it does have is a strong sense of community, a willingness to share resources and a need for self-sufficiency, so Toki has developed a small peer-to-peer network of homes with solar and batteries to test the concept. The cheapest electricity you can generate is on your own roof, and the second cheapest should be from your neighbour's roof. And when you add batteries into the equation, it makes that energy more useable when it's most needed.
Toki, who is also the founder of successful skincare brand Aotea, is showing how modern technology can improve energy security and reduce energy poverty. And just as New Zealand could be a demonstration project for the world to follow, Aotea could be a demonstration project for other off-grid islands to follow.
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."
