I'm not saying this plan is good, but I wanted to add some perspective. So there is an 850 MW solar farm in China. It's one of the largest in the world. It covers 8.9 square miles. One tenth the land usage. The reservoir would be 0.9 square miles. An average on shore wind turbine produces about 2.75 MW so you'd need about 310 of them. That works out to 20-40 square miles. Of course in the case of wind you can use that land for other things, which is good. But York County isn't exactly great place to build wind turbines. I'm not even going to bother to do math on geothermal.

I'm just talking about land usage so far. You also have to consider how you will transmit and distribute that power. You need substations to increase voltage and lower current. You need more lines whether underground or on poles. Distributed generation like on-site solar or small wind turbines with battery banks can work great for lower loads in densely populated areas like homes in cities. It is definitely something we should be doing a whole lot more of. But managing a grid is just insanely complex.
