I just watched a great TED talk by Bill Gates. He cogently explains the real threat of climate change, particularly to the world’s poorest 2 billion people. He goes on to describe the urgent demand for an energy breakthrough that can radically reduce the planet’s carbon emissions. He also discusses exciting innovations in nuclear power which, on the face of them, sound pretty convincing:

UPDATE: Thomas Friedman also wrote with clarity about climate change in the New York Times this week.

The technologies are to be used, if valid.
We have presented in Korea, to teachers/professors responsible for the appraisal of these technologies to produce energy from renewable sources, the best and newest technology from renewable sources.
Not only produces three times more wind energy, but the technology at sea currently proposed, no system can compete in the production of energy.
Being the best and highest performance does not mean anything, because even in renewables as in other areas, there are lobbyists who manage these technologies and their presentation, then, after the good word and advanced technologies, and their list, we have the NOTHING.
I hope Hollywood might be interested in our technology, because they alone in the Neverending Story (Die Geschichte Unendliche), managed to defeat NOTHING.
