Our planet is warming up - it is, alas, a fait accompli. Burning fossil fuels floods the atmosphere with carbon dioxide, which creates a greenhouse effect that traps heat near the earth's surface.
To combat it, countries and energy companies have recently been actively investing in clean sources of wind and solar energy. However, as the Washington Post reported, two recent studies have found that wind power is weakening as a result of climate change.
As it turned out, with global warming, wind flows change. Thus, in the course of the first study, it became obvious that the wind speed was decreasing in most of the Northern Hemisphere, as a result of which wind farms in the USA, Europe and China will decrease their efficiency over the next decade.
The second study showed a decrease in energy production from wind farms in China over the past few decades. For example, the intensity of winds feeding power plants in Inner Mongolia and Gansu province has decreased by 15% since 1980.
The wind is a consequence of the fact that the Sun "supplies" different amounts of thermal energy to different parts of our planet. Air currents from areas with excess heat move to where it is colder, creating wind. Climate change is upsetting the natural balance, reducing the speed of air flows.
But even despite these negative processes, wind energy will not lose its importance in the near future, remaining one of the most efficient and cheapest renewable sources. Now, humankind has to work even harder to reduce its dependence on fossil fuels.
