There's 5.5 million tons of known uranium reserves. If you took our current reactor fleet and replaced it with fast breeders, this would supply it for 30,000 years. There's also 4.5 billion tons of uranium dissolved in seawater. Then there's thorium.
You're missing that.
Technically not renewable, but in the long run, neither is the Sun.

- cm2187 5y agoAt the current pace, 30,000 years sounds about right,
- AstralStorm 5y agoIt's not that bad, currently at breakeven point for laser fusion and close to that for magnetic containment fusion. Half a century should be enough, but we lack the time.
