Wind turbines are friendlier to birds than oil-and-gas drilling
boomed in America over the past couple of decades, with the rise of shale gas produced by hydraulic fracturing, or fracking, of rocks. Production rose from 37m cubic metres in 2007 to 740m cubic metres in 2020. Comparing bird populations to the locations of new gas wells revealed an average 15% drop in bird numbers when new wells were drilled, probably due to a combination of noise, air pollution and the disturbance of rivers and ponds that many birds rely upon.
When drilling happened in places designated by the National Audubon Society as “important bird areas", bird numbers instead dropped by 25%. Such places are typically migration hubs, feeding grounds or breeding locations. Wind power, in other words, not only produces far less planet-heating carbon dioxide and methane than do fossil fuels.
It appears to be significantly less damaging to wildlife, too. Yet that is not the impression you would get from reading the news. Dr Katovich found 173 stories in major American news outlets reporting the supposed negative effects that wind turbines had on birds in 2020, compared with only 46 stories discussing the effects of oil-and-gas wells.
Wind turbines might look dramatic. But their effect on birds is not. © 2023, The Economist Newspaper Limited. All rights reserved. From The Economist, published under licence. The original content can be found on www.economist.comMilestone Alert!
