'Green' energy right now doesn't even crack 20% of generation if I recall, despite windmills and solar panels going up everywhere.
Bottom line is, you can put a coal, nuke, or nat gas plant anywhere, and it will generate it's designed output evenly and continuously.
Alternative energy is completely dependent on siting. There must be wind, sun, water, or geothermal activity to tap to make it work. Which means you got limited areas where there will be any kind of production to meet demand, much less profitable.
Solar energy isn't practical in Seattle, nor wind in Florida, at all. Or hydro in the desert, or geothermal in farm country.
It simply cannot meet the current demand due to the physical limitations, and the green energy people will not deal with that hard truth.
