For years we have relied on fossil fuels to produce the light, heat and energy we need to live and work. But these supplies are diminishing, and polluting our environment. So can renewable resources step into the breach annd produce enough energy to power the world? In this special Naked Scientists show, live from the Cambridge Science Centre, we talk to some of the researchers trying to do just that, as well as conducting some energy-related experiments of our own...

Nuclear fusion would seem to me to be the answer. As I understand this technology should be available in 20-30 years time if not sooner. Am I correct here?

In reply to the podcast:

The general view now is that wind power, on land is the cheapest form of [electricity] generation.
- Not true at all. That's the view of  greens.  It's not a scientific view but a political one.

Roger:
Nuclear fusion has never been demonstrated for energy creation. It's only been done for tiny periods of time. We must put far more energy into fusion than we get back. I'd be shocked if we get fusion working within this century, as a source of usable energy.

Compared to fusion, nuclear fission is easy, cheap and safe. Many new fission reactor designs are planned such as molten salt reactors [nofollow] [MSR]. These can easily close the fuel cycle, so producing the least possible waste. Because MSRs run at normal pressure they are intrinsically safer than current reactors using a pressurized reactor cooled by water. MSRs can also be designed to be passively safe by manipulating reactor physics. These improvements offer orders-of-magnitude safety improvements over current fission reactors, and current fission is already the safest form of energy [and electricity] generation.  [safety is specified here in terms of the number of accidents and fatalities per unit of energy created. E.g. For accidents, working at a nuclear power plant is 4 times safer than working in an average office.]
