Just like with ethanol, show me where it works, economically, without government subsidies and we'll see.

Electrical and wind are supplemental power sources (as are hydro electric and geothermal) until they aren't. "They aren't" happens when they can produce enough for our commercial and industrial demands.

In 2018 - Wind+Solar accounted for 8.2% of our production (no one seriously suggests we have much of a power "surplus", although there is surplus capacity in some areas).

To even get to a majority of our demands, those 2 sources would have to increase 6 fold. For renewables (all sources, including hydro), they would still have to triple.

So, I stand by my 50 to 60 years - AT THE SOONEST.

Until then, evil, disgusting, dirty "fossil fuels" will still continue to produce 50 to 65 percent of our electrical power, as they do now.
