Andy Singer breaks down why switching to all renewable energy would be environmentally destructive. Conventional energy sources provide large amounts of energy with minimal land use. Renewable sources like wind and solar take more space to generate the same amount of energy, requiring the destruction of nature.
In terms of power generation related to renewable and safe power, you should check out Thorium nuclear reactors. This type of reactor solves every problem you can think of about nuclear power. It can’t blow up, like Chernobyl. It can’t melt down like Fukushima in Japan. Check out thurium reactors. I think you will be impressed with how many problems it solves.
