UNLIMITED CHEEP ENERGY WOULD TRANSFORM SOCIETY

My Times column on Britain’s energy options:

Until 2004 Britain was a net energy exporter. Today, it imports about half its energy. Some of that, in the form of coal and liquefied natural gas, comes directly from Russia, which also supplies a third of Europe’s gas through pipelines. The unprecedented „gas deficit warning“ of March 2 was a sharp reminder of our dependence on imports.

Yet Britain is swimming in energy. Enough sunlight falls on the country to power the economy many times over. Wind, wave, water and tidal power cascade over us. There is wood in our forests. There are hot rocks beneath Cornwall and Durham, gas under Lancashire and enough coal under the North Sea to last centuries. We could easily buy sufficient uranium to keep us going indefinitely. And if we were to crack nuclear fusion, all we would need is a little bit of water and some Cornish lithium.

So what’s the problem?
