Last year, Europe experienced a significant decrease in wind speeds, leading to what is known as a “wind drought.” Wind speeds in many places dropped about 15 percent below the annual average, with some areas experiencing an even more pronounced decline. The United Kingdom, in particular, saw one of the least windy periods in the past 60 years, resulting in a dramatic impact on power generation. Wind farms in the UK produced only 2 percent of the country’s power in September 2021, compared to 18 percent in September 2020. To compensate for the energy gap, the UK had to restart two mothballed coal plants.

The decline in surface winds in Europe has raised concerns about a potential “global terrestrial stilling” linked to climate change. Research from 1978 to 2010 showed a worldwide stilling of winds, with speeds decreasing by 2.3 percent per decade. However, a study in 2019 found that global average wind speeds had actually increased after 2010. Despite conflicting data, the Intergovernmental Panel on Climate Change predicts a slowdown in winds in the coming decades, with average annual wind speeds potentially dropping by up to 10 percent by 2100.

The weakening temperature difference between the poles and the tropics, driven by the faster warming of the Arctic compared to the tropics, is cited as a key factor in the slowing of winds. Additionally, an increase in “surface roughness” due to urban development has been identified as a contributing factor to the stilling of winds.

Studies have shown that the Arctic has been warming four times faster than the rest of the world since 1979, indicating a potential acceleration in the decline of wind speeds. The impact of wind stilling extends beyond energy generation, affecting plant growth, ocean currents like the Gulf Stream, and even air quality in urban areas.

The uncertainty surrounding wind trends poses challenges for energy production and climate adaptation efforts. While wind energy is a key component of transitioning to renewable sources, the variability of wind speeds necessitates new strategies for energy storage and reliable alternatives. The potential consequences of a significant drop in wind speeds include disruptions to energy markets, increased volatility in prices, and challenges for industries reliant on consistent wind patterns.

As researchers continue to study the complex dynamics of wind patterns and their relationship to climate change, the need for innovative solutions to mitigate the impacts of wind stilling becomes increasingly urgent. The future of wind energy production and its role in the transition to a sustainable energy system will depend on our ability to adapt to changing wind patterns and develop resilient energy infrastructure.
