While there seems to be a neverending deluge of pessimism surrounding the climate change debate these days, there is plenty of cause for optimism as well. One of the biggest examples is how quickly renewable energy is growing as a power source in a vast number of countries. The International Energy Agency last year reported that by the end of 2021, renewable energy will account for almost 30% of global electricity output. In most countries, renewable energy is now cheaper than energy generated by fossil fuels.

Can Wind Farms Slow the Growth of Shorebird Populations?

Vulnerability of northern gannets to offshore wind farms; seasonal and sex-specific collision risk and demographic consequences (2020) Lane et al., Marine Environmental Research, https://doi.org/10.1016/j.marenvres.2020.105196

The Crux

A green on green conflict is what occurs when forms of renewable energy can have a potentially negative effect on the local environment. We see it in hydropower disrupting freshwater fish populations, or in the case of today’s paper, wind farms causing bird deaths. Marine shorebirds are often killed by wind turbines, yet it’s not totally clear to what extent population numbers are impacted by these deaths.

Additionally, whether wind farms are more dangerous to male or female, old or young birds could have a big impact on whether these bird deaths affect population numbers in the future. Today’s authors wanted to investigate this question, using a population of northern gannets off the coast of Scotland.
