There is another problem: These forms of generation are unsuitable for power grid use because they vary their output faster than the traditional power plants can and they don’t generate 24/7. As a result, the traditional plants still have to run at full capacity anyway to back them up. This can also cause overcapacity surges that damage equipment.
How is any of this desirable?
