Let's be honest. Democrats are not fans of nuclear:
https://www.sierraclub.org/nuclear-freeThey routinely oppose hydro and pump back hydro projects. They want a 100% renewable energy future based upon wind and solar power. Two technologies, that although cheap are not viable for full time power production (because they are intermittent). The expansion of solar and wind energy on the electric grid has been coupled with an expansion in natural gas fired turbine plants, which is one of the only current technologies that can adapt to sudden drops in solar or wind power production (other than pump back and traditional hydro plants that are not always viable and are routinely opposed by Democrats).
Their position sounds good for small scale nuclear plants, but the reality is they oppose the construction of the facilities, the facilities take on average 7.5 years to build and they oppose the mining of Uranium, the transporting and processing of the ore and the storage of the biproducts in stable rock formations in the middle of the desert. So Biden's rapid orders on climate change (shutting down the pipeline, moratoriums on drilling permits, etc.) create an immediate constraint in the supply of oil and gas, with no viable alternative to take their immediate place (most of the eco-friendly alternatives will take ten years to come on line).
What this will cause is a rise in gas and oil prices, which will translate into higher electric and gasoline prices in the near term, which will affect everything you buy and the cost of electricity that you pay. It will kill jobs and cause inflation, a hallmark of the Jimmy Carter era.
The reason I know this so well is due to first hand experience. When the democrat controlled PUC in my state mandated the end of coal power in our town and replaced it with a gas fired turbine, some solar and wind power, it doubled the cost of our electricity and caused 7% of our town to have their power cut in the first twelve months (primarily poor and elderly individuals). It killed jobs, had an extremely adverse effect on the poor and hardly had any impact on global warming (any improvements we made were more than offset by the expansion of coal power in China and India and the jobs that went with it).
