Vast onshore wind farms are not a viable option for the UK

Barring a last minute intervention by the Treasury, the UK government will publish its new energy bill within the next few days. As it stands, the bill is a triumph of politics over economics and common sense – a symbolic victory for the Liberal Democrats designed to keep the coalition’s unhappy marriage together.

The problem is that serious investors will not believe a bill that reinforces subsidies to onshore wind, puts no hard numbers on the subsidies necessary for nuclear new build, sidelines the potential of energy efficiency and further technological advances, and completely ignores the issue of energy costs and competitiveness. Read more

Thanks to those who have commented on the post on adaptation to climate change – or at least thanks to most of them.

Just to be clear, I don’t see adaptation as an alternative to emissions reductions but as an essential part of a twin track strategy.  We need both.  As I said, I can’t see emissions being kept low enough to avoid the risk of an increase of around 2 degree C.  That isn’t a statement of what is desirable, but a judgment of the current political reality.  I hope I’m wrong, but watching what is happening in the US in particular, I am not optimistic.  I will write more on the US situation in the run up to the election. Given my lack of optimism I feel that adaptation is an imperative.  But the other track should be pursued as well.  If we don’t limit emissions at all, the risk is that the average temperature change could go well beyond 2 degrees.  Then we really will be in trouble, especially in terms of food production and the fate of low lying territories and their inhabitants. Read more

Evidence from the American space agency NASA published at the end of July shows the remarkable and disturbing degree to which Greenland’s ice cap has melted.  Taken in combination with extreme weather conditions in the US and Asia over the last few months, what is happening in Greenland raises again the unresolved issue of climate change and what should be done to mitigate the associated risks.  But the traditional approach of gradually reducing emissions by changing the energy mix may no longer be a viable option. Read more
