As part of the rebuild, install solar panels on every school - and batteries too. In Australia, they will generate power for export to the grid after school finishes - now the peak period in the day as the noon peak has been shaved by solar PV already. And, during peak demand during the summary, this capacity will be 100% for export as schools are out on holiday.
We were inspired by how Nelly Robinson has connected his suppliers (with no customers, as restaurants in Sydney are closed) with his customers (who were struggling to buy food) via his restaurant, helping to preserve employment for people who were falling between the cracks of government support. When he re-opens, pay him a visit - it's an extraordinary restaurant. In the meantime, Sydney-siders can order from www.nelrestaurant.com.au.
