The way I see it, solar and wind on a small scale makes sense. The application where a house has panels or a wind generator and the power is stored locally in a battery bank. Like a Tesla Powerwall or Generac PWRcell. Not selling it back to the local utility.
The large scale solar and wind farms can provide power when the sun shines and the wind blows. But when it doesn't blow or shine there needs to be power generated with coal, natural gas, nuclear or other 24/7 method. So, why spend all this money on wind and solar if we have to have enough grid capacity to run everything anyway?
I was looking around the house and notice the things that end up running on DC. All the lights in the house are LED, the TV runs on DC, radios, security cameras, etc. Pretty much everything electronic runs on DC. But now each item converts 110 vac to low voltage DC. I would like to build a house made to run on DC. Power it with solar or wind or both and store power on site. Then buy DC appliances or convert existing appliances to run on DC. The problem would be staying warm in the winter and cool in the summer.
As far as the climate goes, it has been changing since earth was a baby. Trying to keep it from changing is a pipe dream. We should be applying our resources to accommodate mother nature rather than trying to change her.
Just my $.02 worth. I've been wrong before.
