Solar energy cost per kWh drop about 90% in a decade. I is currently the cheapest way to produce a kWh of electric power. And it is getting continuously cheaper. Next grid batteries same story. Selling like hot cakes now, soon the extended life, lower initial cost etc will drop by 90% ( soon means a decade or so)
Of course wind has a place and is continuously improving.
What can slow this transition from fossil fuel for electric power? Well in the rest of the world nothing. In the US elect Trump-MAGA. Want to keep up the pace, elect Harris and dems down ballot.
Of course the production capacity can grow but the investment pace to replace natural gas and coal is limited. So decades to reach optimal installation of wind solar and grid batteries.
Heat pumps lowest energy in for home heating.
EV cheaper every year. Industrial production in steel and cement is making remarkable progress plus the new processes are cheaper.

I come from the microprocessor world where continuous improvement in performance and price is a 50+ year track record. The same is true for the technologies above, just a bit slower pace.
