Bill McKibben gets the math wrong on fracking

Posted on Updated on

Gas is leaking from pipes beneath New York City and Bill McKibben has confidently informed us that this is simply more evidence that the climate benefits of shale gas are much worse than many claim. Unfortunately the only real message from the article is that Bill McKibben is rather selective about evidence when it comes to fracking and that his apparent willingness to “do the math” on climate change does not transfer over very well to the rather important question of where we get our energy from.

Picking apart the CCC’s electricity cost projections

Posted on Updated on

This morning the Guardian reported that relying on gas would push up UK energy bills by £600 by 2020, whereas renewables would only increase them by £100. The basis of the article is a report by the Committee on Climate Change. A quick glance at the executive summary of the report makes clear that the Guardian reporter mixed up 2020 and 2050.

How many gas plants does Greenpeace want?

Posted on Updated on

The UK Chancellor George Osborne recently succeeded in getting a scenario into the UK government’s gas strategy. This involved having up to 48 GW of gas capacity in the UK by 2030. It is my view that this amount of gas capacity is, under any realistic scenario, more gas capacity than is consistent with decarbonising electricity by 2030. This view, it would appear, is also held by Greenpeace.

However, let’s consider how much gas capacity Greenpeace wants. Or, more importantly, how much gas capacity we would need if Greenpeace got what they wanted in terms of renewable energy. Read the rest of this entry »

Is London going to be fracked?

‘Fracking’ exploration could affect 60 per cent of UK

A rather frightening headline in today’s Independent. John Sauven, Greenpeace executive director, makes it clear that this claim is not simply a piece of idiocy from a sub editor at the Independent:

Two thirds of England, including large swathes of countryside, is now under active consideration for a risky, polluting, expensive form of fossil fuel extraction. Read the rest of this entry »
