A typical solar farm generates between 0.15 and 0.2 megawatts of electricity per acre. This can vary based on factors like panel efficiency, location, and available sunlight.
So to round that out, that works out to about 100 megawatts per 640 acres which is 1 square mile. So 100 megawatts per square mile.
A typical large coal burning power plant can like Plant Bowen between Rome and Cartersville, Georgia produces 3,450 megawatts.
So it would take 340 square miles to produce as much solar power as a large coal power plant.
That would be most of Etowah County, Alabama completely covered in solar panels.
The solar projects I have mitigated are basically a full section or a half section. so thats 640 acres or 320.
The reason these data centers are going for solar is speed, not for being green and anti-coal or anti-nuclear. A solar farm can be planned and be generating power within a year. They dont generate power like a burner plant does but they get built much faster. Any kind of burner plant (coal, gas, nuclear) takes much longer. Even if the regulations that slow them down were tossed, they still have to be built. A solar farm can be built damn near overnight and they can start generating power as soon as the first panel is set in place.
I'm not anti-solar, just being a realist. Solar and wind have their place, but we have to use all the arrows in the quiver to supply the power the world will need.
I designed air pollution control for power plants. I doubt we will ever see a new coal fired power plant being built, that's just not going to happen, that time has passed, however natural gas fired combined cycle plants are very common and fairly easy and relatively quick to build using a common architecture.
Southern Company has probably built the last large scale nuclear units over at Plant Vogtle. Those were the first new ones in 30 years and will probably be the last.
The future of nuclear will be in small modular reactors used in a distributed power production model.
