I am baffled by people who keep thinking the administration or the government can wave a wand and make something happen.
This is not a matter of government waving a wand-- it is a matter of government setting air quality and vehicle mileage standards, thus shifting the incentives.
We all need an atmosphere that will not heat up the earth to the point that floods our coastlines and causes massive societal disruption, especially for young people, their kids, their grandkids, etc. Right-wing boomers of today don't give a shit, because they will not experience the brunt during their brief and selfish lifetimes.

Having said that, a big mistake made by those who advocate for stricter controls on greenhouse gas emissions is constantly saying that it is an economic winner in the short term. It is not. Any major conversion of this scale will require sacrifices by the current generations.
GHG emissions-reduction activists should not promise a renewable energy economic boom in the short term. Don't make promises you can't keep. That will only lead to selfish assholes like Trump getting elected and goosing the stock market by dropping all regulations and flooding the market with as much fossil fuel as possible.
Any cheap politician can play that trick, but it is equivalent to having a person with a heart condition go on an extended cocaine or meth binge. Yes, you may feel better in the short term. So what?
Long term, it does make economic sense to reduce GHG emissions as quickly as possible. Short term, it will require sacrifice. Can we develop a new "greatest generation"?
