Tax the fucking rich. If you use or produce gas/oil/coal at an industrial scale, your taxes should be an incredible burden. Most citizens don't have an option to choose their fuel source, most of us don't even get a choice of god damned ISP.
Despite being just an conditioner with 2 extra valves, heatpumps are insanely expensive. And thanks to their high price and a 24/7 public slander campaign no one wants to buy an electric car. Fuck.
Before you even start, a modern heatpump will work with outside temps down below -20 and you don't need a car with a 700km range and 90 second charger, you need 200-300km and a 15amp outlet because all you do is drive your broke ass too and from work 250 days a year.
