Solar isn't something that can ever be replenished. There's a fixed quantity of fuel in the sun. Once it burns out, it's gone. That provides the input energy into the process for solar, wind and wood.
With breeder reactors the uranium in seawater would last us 15 million years at current nuclear power consumption levels. If that's not renewable...
There's no such thing as infinitely renewable.
- otherme123 5y agoI though it was already clear that we were talking human scale. And you still talk about 4,500 million years as non-renewable, but 15 million years (plus 100% magic ocean harvesting) as renewable. At no point anybody said "infinitely renewable", and you arguing it makes that a strawman argument. Renewable is defined, like it or not, as a source that replenishes in a finite human scale (roughly, 50-100 years). Sun, waves, hydraulics and wind "replenish" everyday. Wood takes about 30 years. If you find yourself saying things like "15 millions years" or "60,000" years, it's not renewable.
