This week saw the release of a government report into gas fracking in Britain. So far there have only been a couple of test wells drilled in the UK, and drilling was suspended when it was suspected that it had caused a couple of minor earthquakes near Blackpool. The government commissioned an investigation to make sure it was safe, and that was delivered this week. The conclusion is that yes, the, but they weren’t sufficiently severe to stop drilling altogether.
The report has had mixed reactions. Enthusiasts say shale gas is a vital part of Britain’s future energy mix and we should frack on with it. Opponents say it’s dangerous and polluting, a recipe for earthquakes and flaming tapwater. As we decide whether or not to pursue fracking in Britain, it’s really important that we ask the right questions. We have a decision to make, and we mustn’t let the debate be dominated either by environmental paranoia or energy security optimism.
What do we know about fracking so far? Not much, really. It’s been a fairly niche technology until quite recently, and the evidence is still coming in. We know it does cause minor earthquakes – the same as coal mining. We know that ground water can be polluted, but only if something goes wrong. In theory, fracking takes place well below the water table and the pipe is steel lined, so no waste water should leak into drinking water. In reality, that does occasionally happen. It doesn’t occur as often as some opponents seem to imply, but that’s little comfort to those who do experience it. When it happens, there’s absolutely nothing you can do to fix it. So what standards we are going to put in place to make it as safe as possible? If it does go wrong, how are people going to be compensated? And is it a risk we’re prepared to take?
One of the biggest dangers of fracking is actually rarely discussed – land speculation. For all the talk of the gas boom in the US, the biggest fracking company in America makes . They buy the rights, put in a couple of test drills, hype the results and sell on the land for many times the original price. It’s creating something of a bubble that threatens to undo the whole US gas resurgence. As the citizens of Sussex and Lancashire come to terms with local fracking, they should be aware of the potential impact on land prices. How are we going to ensure that farmers and other rural land users aren’t priced out of the market? How is Lancashire going to balance the needs of its dairy farmers and market gardeners with those of the fracking industry?
Another reason for concern is that fracking is a thirsty activity: each well requires millions of litres of water. One of the big areas of exploration in Britain at the moment is Sussex, which the Environment Agency . We should be asking where the drilling companies intend to get their water from.
Ultimately, the main reason to oppose fracking is that it is a fossil fuel. A fracking boom in Britain is incompatible with our carbon targets, and shale gas won’t do anything to fix the long term sustainability of our energy systems. We need ask how seriously we take climate change.
Finally, one thing is for certain: shale gas is not a genuine solution to Britain’s energy problem. As the below shows, it cannot possibly compensate for the decline in North Sea production. Whether we pursue fracking or not, we’ll still have increasing gas imports. Even a gas boom (green sector below) would scarcely make a dent in our rising gas bills. With or without shale gas, Britain’s era of cheap energy is over. Which implies the question: it fracking even worth it in the first place?
I suspect that fracking will get a cautious green light from the government, but I doubt they’ll want to be seen encouraging it too loudly. I also suspect that the drilling companies will face such a massive PR battle with local communities that fracking will face a similar fate to wind power in the UK: lots of potential, held back by nimbyism and scaremongering. The big difference between the two is that wind is a free and renewable resource and harnessing it is a harmless process, while shale gas is non-renewable and climate-altering and drilling for it is potentially dangerous. I know which one I’d rather invest in.
