I‘ll make the switch to working for a company in the solar energy space soon. Found it through climatebase.org, a huge job board for anything in the broad space. There are quite some companies in need of good software engineers. Are all of them doing „the right thing“™? Probably not. Is this huge problem with so many smaller things to solve worth taking a shot at? Sure. This needs all hands on deck, so begin the search, apply and learn on the way.
