- corysama 15y agoAccording to Gates in his TED talk (reference elsewhere in these comments) the US has enough nuclear waste stockpiled to power the country for 200 years. After that, we can get enough thorium(?was that it?) from ocean filtration to continue for the imaginable future. Hopefully, before then we'll have switched to 100% solar.
- pjscott 15y agoFar in the future, the sun will expand, turning into a red giant, engulfing the earth and boiling the oceans away. Ultimately, it will turn into a white dwarf. This hardly counts as renewable energy; it's just really vast energy. Nuclear energy is far less vast, but still huge compared to what we're using today. If you think of easy energy sources as civilization's starting capital, nuclear can give us a very long runway.
