New Zealand is going to need a lot more electricity as homes and businesses swap out fossil fuel machines for much more efficient electric versions. MBIE has just released a report showing a range of different scenarios and under favourable economic conditions the demand for electricity could rise by 81 percent by 2050. Where we get all that extra electricity from is an important strategic question for New Zealand and the report says wind and solar will be the "least cost" way to meet this demand. At Rewiring Aotearoa, we believe a lot of the extra electricity we need could come from rooftop solar and because it is produced where it is used it is the cheapest form of delivered electricity New Zealanders can get. Batteries are also dropping in price and rooftop solar and battery combinations can reduce peak loads while saving on energy bills. This is vital context for how we choose to build out the energy system to be low cost and highly resilient.

With 60kW of solar, a Nissan Leaf as a 'farm quad', electric mowers, an electric ute that can run a water blaster, and even a chicken manure scraper made out of a wrecked Tesla that, as Rewiring's Matt Newman says, looks a bit like something out of Mad Max, "almost everything is electric". There aren't many others in New Zealand who have gone this far down the electric road. And, with his electric Stark Varg, the fastest off-road motorbike in the world, he's obviously having plenty of fun on that road, too.
