2. None of the proposed liberal alternative energy sources- solar, wind, water- pay for themselves. Maybe they will someday but they don’t.
I have no idea where you get your information from, but whatever is implied here is simply false.
Newly developed renewables (wind/solar) are the cheapest form of electricity on the planet on a $/kWh basis (Lazard, 2020) and getting cheaper by the day due to technology/learning curves.
The primary issues with renewables is not cost, but a) intermittency (i.e. not predictable, and don't provide energy 24/7 unless have storage) and b) lack of transmission line infrastructure to get electricity from optimal generation geographies (e.g. desert Southwest, windy North Dakota) to population centers.
Nuclear and fossil fuels are more expensive, but are highly predictable generation sources, run 24/7 and thus fit best with the way the electric grid was constructed.
The notion of achieving a zero carbon future by simply ditching renewables and 100% swapping nuclear for fossil fuels is highly misguided and misinformed.
