David MacKay's TEDxWarwick talk uses basic arithmetic to show how much land and energy renewables would need to power a country like the UK. It explains the limits of sustainable options and why they should still be pursued.
HN 推荐的原因： Cited in energy debates for its back-of-envelope scale of the transition and the land and storage limits of wind and solar.
