What they don't mention are the subsidies that solar and wind energy receives, and that those energies NEED fossil fuel and nuke energy transmissions to sustain them.
The generation of electricity with coal and nuclear is becoming unprofitable.
Some big utilities actually want to get out of the generation business totally and only transmit/deliver electricity because the government guarantees that they will make a profit.
So, generation and transmission are ultimately being forced to become separate businesses. You will buy your electricity from one company and it will be delivered by someone else.
When coal and nuclear are gone prices will rise and the grid will become unstable. Rolling brown/black outs will be the norm for summer and people will die because they don’t have air conditioning during heat waves.
