The anti-renewables bandwagon is rolling ever faster. This started some time ago, but has now started to bite on policy, as seen in the EU’s 2030 proposals which contain no binding renewables target. There is an emerging view, to be found especially amongst economists (including The Economist) and on the centre-right (as opposed to the hard right anti-all climate policy view) that the focus should shift away from renewables support and back towards carbon pricing. Carbon pricing, the argument goes, will deliver emissions reduction at least cost. The implication is that, because it will be much cheaper than renewables, it will be politically a lot more popular, or at least easier.
I see two reasons for thinking that it’s not as simple as it seems, and that putting all hope in carbon pricing and backing off from renewables policy may run into trouble. Continue reading
At the conference of the British Institute of Energy Economists yesterday, one of the speakers (the conference was held under Chatham House Rules) poured scorn on German energy policy, pointing to the €200 billion that will be paid out in subsidies over the next 10 years to renewables, the offshore wind turbines kept going by diesel and the socialisation of costs incurred where developers face delays. Economic efficiency, he said, should be at the heart of energy policy, Germans have ignored this and have paid the price. By contrast, Continue reading
I have been looking at long-term trends in grid electricity carbon coefficients (i.e. how much CO2 is generated across the whole electricity system to produce a given amount of power). This is a good overall indicator of the sustainability of the electricity system in a country from a climate point of view, and is determined by the fuel mix.
The climate book of the moment is The Burning Question, by Mike Berners-Lee and Duncan Clark. It comes adorned with glowing recommendations from an amazing array of big figures, from Al Gore and Jim Hansen to Mike Barry of M&S and Sam Fankhauser at the LSE. Of recent books on climate change, it is the one that seems to have touched a nerve, making it high up on the bestsellers list at the Guardian.
And this is indeed the best three-quarters of a book I have read on climate change Continue reading

The idea that the best way to provide energy is simply to avoid unnecessary use in the first place has been around for some time. Back in 1989, Amory Lovins coined the term “negawatts” (energy saved by cutting out waste) to emphasise the contrast with megawatts of power or heat that needs to be generated if that waste is not eradicated.
