What does it help to build solar power plants only to use up all of that capacity on useless computations?
All else being equal, building solar panels is a negative; producing and transporting solar panels consumes materials and produces CO2. The reason building solar power plants is usually good is that they reduce the need for even worse forms of energy production. If you build a solar farm, just to waste all or most of the energy it generates, what you have done is a net negative for the environment.
This is in addition to the fact that a whole lot of mining uses existing infrastructure, which negates the gains from building out clean energy and keeps demand high enough to require dirty energy, as /u/oofbey covered.
