Who said that we are abandoning AE?
Wind WITHOUT subsidies is cheaper than coal all over the nation. 
In addition, unsubidized wind in a few areas, is actually cheaper than nat gas (and that is at TODAY's PRICES). 
With wind turbines going higher into the stronger steadier wind, it will likely become a good % of our electricity (as in 20-25%) by 2025 if not sooner. 

Solar is interesting, but we are doing it wrong. The subsidies on it should be stopped on new homes/buildings. Instead, we should simply require that all new buildings below 6 stories to have enough on-site AE to equal or exceed the HVAC energy usage.
But who is pushing solar? In general, state, local gov and utilities.  

Trump can not push any more coal than he has done already. It WILL NOT happen. 
What is needed is for us to push development of nuclear SMRs, and do this QUICKLY. 
Oddly, state gov and utility are pushing this more than our fed gov.
