A typical nuclear power plant produces 1,000 megwatts of electricity per hour.
At 25 megawatts to 1500 acres for a nice wind farm of 60 to 70 turbines, you would need 60,000 acres and 2400 to 2800 wind turbines to equal 1,000 megawatts. Of course, these wind turbines only produce that much power when the wind is blowing just right. That only happens about 25% of the time, so you really need four times as many wind turbines and four times as much space to produce, on average, 1,000 megawatts of electricity per hour. So that's, 240,000 acres and 9,600 to 11,200 turbines. 240,000 acres is 375 square miles.
At 5 acres of solar panels per megawatt, you need 5,000 acres of solar panels to equal 1,000 megawatts of electricity. Those solar panels only work at peak power levels during the sunny times, so, on average, they only put out about 25% of their rated capacity. That means you really need 20,000 acres of solar panels to generate 1,000 megwatts of electricity per hour, on average. 20,000 acres is 31.25 square miles.
We aren't going to put them anywhere. They are way too expensive and they don't provide a stable enough power supply to rely on. Anyplace with enough open spaces, enough wind or sun shine to be a good candidate is too far away from the east and west coasts where that power is needed most.
By comparison, the Fermi nuclear power plant near Monroe, Michigan sits on a site of about 2 square miles and produces 1,150 megawatts of electricity 24 hours a day for 18 months straight. Then it needs to be shut down for a month for maintenance and refueling and it can go right back to making power 24 hours a day, rain or shine. They are even thinking about adding another reactor that will double the output of the plant on the same amount of land.
