Compared to coal and oil, shale gas offers the prospect of greater energy independence and lower emissions of carbon dioxide and other pollutants. However, fracking is controversial due to the local externalities it creates – particularly because of the potential for groundwater contamination. This column presents evidence on the size of these externalities from a recent study of house prices. The effect attributable to groundwater contamination risk varies from 10% to 22% of the value of the house, depending on its distance from the shale gas well.

Natural gas is seen as an attractive source of energy – it is cleaner than coal and often more reliable. But there are potential risks from the drilling and hydraulic fracturing process. This column shows how shale gas extraction could reduce property prices, and argues that policymakers need to bear this in mind when thinking about the costs and benefits.
