Can we meet global energy demands with nuclear power?

An international team of scientists suggests that we must ramp up energy production by nuclear power if we are to succeed in warding off the worst effects of greenhouse gas emissions on climate change. The team suggests that beginning in 2020 we could achieve an annual electricity output of 20 terawatts without needing to develop carbon dioxide trapping and storage technology for the tens of billions of tons of emissions that would otherwise drive global warming to catastrophic levels.
