Most of physics is about energy, and physicists understand inefficiencies. I wanted to write a book about our energy options in a neutral, human-accessible form.

The discussion about energy options tends to be an intensely emotional, polarised, mistrustful, and destructive one. Every option is strongly opposed: the public seem to be anti-wind, anti-coal, anti-waste-to-energy, anti-tidal-barrages, anti-carbon-tax, and anti-nuclear.

We must not let ourselves be swept off our feet in horror at the danger of nuclear power. Nuclear power is not infinitely dangerous. It's just dangerous, much as coal mines, petrol repositories, fossil-fuel burning and wind turbines are dangerous.

I would like to help people have honest and constructive conversations about energy. We need to understand how much energy our modern lifestyles use, decide how much energy we would like to use in the future, and choose where we will get that energy from.

I was distressed by the poor quality of the debate surrounding energy. I was also noticing so much green wash from politicians and big business. I was tired of the debate - the extremism, the nimbyism, the hair shirt. We need a constructive conversation about energy, not a Punch and Judy show. I just wanted to try to reboot the whole debate.

Fridges can be modified to nudge their internal thermostats up and down just a little in response to the main's frequency in such a way that, without ever jeopardising the temperature of your butter, they tend to take power at times that help the grid.

We can't be anti-everything - we need an energy plan that adds up. But there's a lack of numeracy in the public discussion of energy. Where people do use numbers, they select them to sound big and score points in arguments, rather than to aid thoughtful discussion.

When the Industrial Revolution started, the amount of carbon sitting underneath Britain in the form of coal was as big as the amount of carbon sitting under Saudi Arabia in the form of oil, and this carbon powered the Industrial Revolution, it put the 'Great' in Great Britain, and led to Britain's temporary world domination.

All renewables, much as I love them, are diffuse. They all have a small power per unit area, and we have to live with that fact.

I was writing a book about sustainable energy, and a friend asked me, 'Well, how much energy do you use at home?' And I was embarrassed. I didn't actually know.

Fusion power is speculative and experimental. I think it is reckless to assume that the fusion problem will be cracked, but I'm happy to estimate how much power fusion could deliver, if the problems are cracked.

The bottom line in 2007 is that enrollment costs are going up substantially, drug coverage is declining and the brand name coverage in the doughnut hole is being eliminated... Medicare D is an insurance program, not a benefit. As consumption increases, so too will cost. The changes in 2007 clearly demonstrate the limitations of the program.
