Well. It isn't being drawn from renewable resources, nor will it be in the near future. Renewables are great, but there are a lot of hurdles to overcome if we want to use renewables for all of our energy. In the US, all of the industry, manufacturing, etc. alone will need coal/natural gas plants for some time. We just simply cannot get enough renewable energy out of our available methods. That doesn't mean we shouldn't push towards that of course, but this is a whole different topic.

It is weird to burn a bunch of natural gas and coal to produce a gallon of water in the middle of a desert. And only rich folk can afford to do so.

We all share the energy infrastructure in the US. It is regional, but it is a shared UTILITY. Huge draws of power increase the cost of electricity for everyone, not just the consumer of said power (to some extent, some power companies will charge you more if you have large surges). If you ever work with a power company commercially, you would understand that unnecessary power consumption raises the costs for everyone.

There is simply not enough solar power available to meet our energy needs (nor will there ever be unless we CONSUME LESS POWER) and because your argument hinges on this, I don't know what to tell you..
