> Coal is 20% not most
You’re right ! US has shifted from coal ... to Natural Gas !
I don’t think that this is solving the problem , natural gas comes from fracking ... but it’s definitely a small win knowing how big is America and how much less natural gas produces CO2.
Natural gas is already a big step as it only emits 2/3rds of the CO2 per kWh compared to coal (high hydrogen content). Also, gas power plants can be regulated faster than coal power plants, so they work much better together with wind/solar power and make the transition easier.

It’s not an either or problem. It’s an also problem. Make power plants cleaner and make cars cleaner. Hit it from Both ends.
