People opposed to a clean economy argue that birds get killed by Wind turbines so therefore we shouldn’t build wind farms. Of course, those same people would argue that we should stick to planet-killing fossil fuels instead; somehow, in their minds using fossil fuels is better than renewables when it comes to protecting nature. To hopefully put this ridiculous debate to bed The Economist has stepped in. The magazine that is trapped in the last century agrees that when it comes to power generation and protecting nature that renewable energy is best.

But Dr Katovich did not confine his analysis to wind power alone. He also examined oil-and-gas extraction. Like wind power, this has 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.
