A decent size nuclear plant is 2 gigawatts. If it runs 8000 hours per year out of 9000, it's producing 16 billion kilowatt hours of electricity in a year. That's a nice sized chunk - probably roughly what Niagara Falls produces for NY. But NY needs 300 billion or so kwhr in a year, so we need a lot of those.Meanwhile, a square foot of solar panel produces about 20 watts, but only for about 1200 hours per year (in NY), so only producing a measly 24 kwhr per year. Sounds like I'm making a case for nuclear, eh? But wait, a square mile is 27 million square feet, and so produces 650 million kwhr per year. Ratchet that up to 25 square miles and you've got the same output as the nuclear plant. So which do you think is simpler, cheaper, and easier to install? One decent sized nuclear plant or 25 square miles of solar panels. The record shows it's the solar panels. |
