The state of California is making a big push towards sustainable development and decarbonization. The state government hopes to produce all of its electricity with zero emissions by 2045. Local governments are pursuing similar goals on their own. The city of Berkeley recently banned new buildings from installing infrastructure that relies on natural gas. The University of California has adopted a similar policy and refuses to install new devices that rely on fossil fuels under most circumstances. It is likely that more and more areas will adopt similar policies over time. Of course, those places still need heating for their buildings. They simply need to find a way to get it while maintaining their decarbonization goals and cutting emissions.
