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. David J. C. MacKay accessiblebookenergy Change image and share on social
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. David J. C. MacKay burncoaldanger share on social
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. David J. C. MacKay addaidanti share on social
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.

The United States consumes power per land-area at a rate three times the average. Even though they are more energy efficient, densely populated industrial countries like Germany, Britain and Japan have even bigger power consumption per area. David J. C. MacKay areaaveragebig share on social
Solving climate change is a complex topic, but in a single crude brush-stroke, here is the solution: the price of carbon dioxide must be such that people stop burning coal without capture. David J. C. MacKay brushburncapture Change image and share on social
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. David J. C. MacKay areadiffusefact Change image and share on social
The only thing that really scales up apart from nuclear is solar power from other people's deserts. David J. C. MacKay desertnuclearpeople Change image and share on social
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. David J. C.

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. David J. C.
