Hybrids still run on liquid fuel all the way up. Battery electric farm combines or mining earth movers are feel good wishful thinking designs. Memes. That their meager run times can replace a liquid fueled heavy machine. They are not in widespread use anywhere. The best hope might be for corded farm machines running in a circle around numerous built out high power electric terminals. There is no battery or corded replacement for concrete trucks running back and forth to millions of wind turbine installs.

The point is that the free market is completely short sighted in the timeline of how long humans will strive to exist. We are totally blowing our one time fossil energy gift on cruise ships and football stadiums, ect.
.
The USA alone is forecast, including the most optimistic efficiency gains from electric conversion, heat pumps, ect, to require 1,000,000 2.5MW wind turbines and 5,000 500MW solar farms, in order to replace all energy (which still leaves a big question as to how to use this electricity to make and use Methane or Hydrogen to replace all liquid fuels). To get this done by 2050 we would need to manufacture and install 90 turbines per DAY. Every day. For 30 years. And manufacture and install a 500MW solar farm every 2 days. And before that is even done, we will have to rebuild all of it starting with the first ones again. Just for the USA. Multply this time 6X at least for the World. Not including another 30% population growth to 10-11 Billion. And improvements in standards of living. 3 Billion people still cook by burning sticks.

People have no understanding of the scale of our dilemma.
