Non-renewable? All that salt in the ocean isn't going anywhere and we'll have fresh water as long as the water cycle continues. You could even use grey water waste from fresh water that was originally desalinized for human use.
I mean, you could say solar is non-renewable because the sun die one day. After all, there is a finite supply of solar energy.
- tathougies 7y agoThis is actually a form of solar energy anyway because it is the sun that provides the initial energy to separate the water, and move the water into the atmosphere against gravity.
- nkrisc 7y agoHah, great point. I guess you could take the unnecessarily further and state that all energy potential on Earth ultimately derives from the sun. We're 100% solar already!
- ouaiueoaieaeoiu 7y agoI'd say most of the chemical energy on the surface of the planet is derived from solar power, in contrast to nuclear (fusion or fission) power. Of course, solar is nuclear too. So we're actually 100% nuclear powered.
- benibela 7y agoNot nuclear or geothermal power
- quasimodem 7y agoWe could have never developed nuclear without the sun getting us started though...
- tathougies 7y agoWell, no not all. Batteries (non-rechargeable) and nuclear are given energy by previous supernovae, I would assume.
