Solar and wind generation is great for about 1/3 of our needs.
Beyond that and it doesnt work. Sun doesnt always shine, wind doesnt always blow. We need the old reliable coal, hydro, nuke to provide the 2/3. Natural gas could be a part of it (is a big part now) but if we are supposed to shut down all petro drilling and shut down all pipelines then it cant be any more.
Fruther to get to 1/3, we need many more power transmission lines crisis crossing the country, at substantial cost. If we did this, it will take time. Decades. Not the 12 years or less some fools propose.
Clearing the ground for windmills, solar especially, and power lines will take a lot of land out of food production. This is a concern that must be addressed. Placing the panels on city roofs would be a good start, but there doesnt seem to be enough effort in that, and maybe not enough roofs. I dont think people understand the scope of acres needed to accomplish replacing 1/3 of our energy production.
Solar panel and battery technologies have advanced a lot in the past 50 years. We are down to the small half a percent advances any more. Someone would need to stumble upon a real game changing breakthrough out of left field to really make a difference any more on batteries and panels.
Mining the exotic rate materials used for panels and the better batteries is neither clean nor efficient, so the actual real gains over present energy is pretty negligible. Seems the goal of change is more important than seeing an actual improvement.

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
