Bill Gates has harsh words for solar substantially supplying the grid.
Watched a couple of his youtube videos. Interesting that he stated that it is the installation costs of solar power than makes it non-competitive in spite of cheap panels.
Is there a realistic way to affordably install commercial solar?
Gates feels that nuclear offers the best option. I happen to agree, especially now that we can turn uranium 238 (depleted uranium) into viable nuclear fuel. We have enough depleted uranium to supply our energy needs for years. We also have better cooling technology which makes nuclear much, much safer.
As an aside, it is somewhat interesting that an ~100 billion dollar man spends his time watching youtube videos - or other informational videos. He is definitely a knowledge geek.
