Nuclear power is the only way to stop making CO2 that actually works. To stop Global Warming, we must replace all large fossil fueled power plants with nuclear.
Renewable Energy mandates cause more CO2 to be produced, not less, and renewable energy doubles or quadruples your electric bill. The reasons are as follows:
Since solar works 15% of the time and wind works 20% of the time, we need either energy storage technology we dont have or ambient temperature superconductors and we dont have them either. Wind and solar are so intermittent that electric companies are forced to build new generator capacity that can load-follow very fast, and that means natural gas fired gas turbines. The gas turbines have to be kept spinning at full speed all the time to ramp up quickly enough. The result is that wind and solar not only double your electric bill, wind and solar also cause MORE CO2 to be produced.
We do not have battery or energy storage technology that could smooth out wind and solar at a price that would be possible to do. The energy storage would "cost" in the neighborhood of a QUADRILLION dollars for the US. That is an imaginary price because we could not get the materials to do it if we had that much money.
The only real way to reduce CO2 production from electricity generation is to replace all fossil fueled power plants with the newest available generation of nuclear. Nuclear can load-follow fast enough as long as wind and solar power are not connected to the grid. Generation 4 nuclear can ramp fast enough to make up for the intermittency of wind and solar, but there is no reason to waste time and money on wind and solar.
