Wind and solar power aren't cheap because their fuel is free. They require ten times more steel and concrete than natural gas plants to produce the same electricity, plus expensive transmission lines to reach distant demand centers. Material and infrastructure costs, not fuel, drive the real expense.

People mistake about energy. Like everyone says, well, you know, wind and solar, they're ultimately going to be cheapest because the fuel is free. The fuel is just one component. In a natural gas power plant, the price of natural gas, it's only like a third of the cost of the electricity. Really, the more important cost is the cost of the machine that harnesses the energy and then the grid and the facilities to deliver the energy. The problem of wind and solar has been the machines are huge. They're 10 times more steel and concrete and expensive materials than a natural gas power plant to harness the same amount of energy and way more land. And then additional transmission facilities, 'cause they take a lot of land to build these in. And then you gotta build them away from the cities and then you gotta transport the energy to where people want it.
