energy credit

[Insignia]

Hello I recently sold a home and have capital gains on it I heard that there is an energy credit that just got approved is that true. Can I buy a energy approved car this year and get tax credit on it? Also if I buy a home before this year and do solar this year or if I am not fast enough and end up doing it next year before the tax season can I write of this year capital gains from my house sale from it? Or if I try to start a business like cutting grass this year can I write off the car that I get from my capital gains from it? Also is their other things that can help offset my capital gains I have this year?

If I use the capital gain to buy a car to work for door dash or uber am I able to write it off my capital gains with it?
