A wind farm requires 700 times more land to produce the same amount of energy as a fracking site. An analysis by Prof David MacKay, the British energy department’s recently-departed chief scientific advisor, shows that in order to produce the same amount of energy over 25 years (0.9 billion cubic metres of gas and 9.5 TWh of electricity respectively), a shale gas site requires just 2 hectares of land, whereas a wind farm capable of producing the same energy would span an area of 1,450 hectares, requiring 87 turbines each 328-foot tall. A solar farm generating equivalent energy would span a 924 hectare area, directly building on 208 hectares of it. Fracking would therefore be far less intrusive on the landscape (not to mention the public budget: theguardian/business/economics-blog/2013/jul/16/bowland-shale-fracking-uk-economy-co2-emissions) than wind or solar energy.
