Jesse Ausubel explains how wind power, hydroelectric and solar may be renewable, but are not green. Nuclear power is the only way to satisfy the world's appetite for energy, which will not and should not decrease, in an environmentally friendly manner.
Nuclear has lots more potential than we're using. The only major problem it has is public prejudice. Absent that, the sustainability, safety and security problems can all be solved.
