Chris Rhodes has drawn my attention to his blog, linked above.
I would be extremely grateful if other bloggers who cover the question of the realities underlying our future energy supplies would do the same.
If we politicians are going to make sensible decisions, we need to have a grip on the total implications of the energy policies which are being touted around, and not allow ourselves to be seduced by the latest rabbit out of a hat. I find it very difficult to locate information sources which even approximate the truth: so much of industry, and so many pressure groups, seem addicted to lies and distortions.
Claims are made about the energy efficiency of different models of cars, based only on their fuel consumption rather than on their lifetime energy cost. Wind turbines are hymned as the solution to our problems, on the basis of a 15 year payback! Fuel cells (with which I was commercially involved for a while) are promoted as 60% efficient without taking into account the inefficiencies that flow from creating and storing and transporting their fuel.
Chris Rhodes's latest posts address the mathematics of biofuels. Good Stuff.
