Renewable Energy: Climate Crisis 'May Cause Faster Wind Speeds' | Life environment

According to global research, the global climate crisis could lead to the production of more renewable electricity by encouraging faster wind speeds for the growing world of windmills.

Scientists have discovered that the changing patterns of ocean circulation in the world can cause a rapid increase in wind speeds in the last 10 years.

An international research team has analyzed data from 9,000 international meteorological stations since the late 1970s and found that wind speeds had increased unexpectedly after a slowdown in three decades.

Dr. Henzhong Zeng, a professor at Princeton University and lead author of the report, said the research team was surprised by the findings as it began to study the slowdown in global wind speed.

Faster than expected wind speeds could help increase the amount of renewable electricity produced by winds by more than a third to 3.3 million kWh by 2024.

Zeng said the unexpected acceleration would probably play a greater role in improving wind efficiency in the United States than technological innovation.

The research paper, published in the peer-reviewed journal Nature of Climate Change, suggests that faster global speeds could continue for at least another decade, which would be a big boost for wind owners.

Dr Adrian Chappell, a professor at Cardiff University and co-author of the report, said the rapid increase in global wind speed contributes to the expansion of renewable energy that will be critical to maintaining global warming below 2C.

The findings mark a major reversal in the trend of declining wind speeds in the last three decades – known as global land longing – that threatened to halve the world's wind power potential by the end of the century.

We believe that the escalating climate crisis is the defining issue of our lives and that the planet is in danger of emergencies. We know that our readers and supporters around the world are passionate about this, as many of you have said.

We want the Guardian to play a leading role in environmental disaster reporting. So at The Guardian we commit to the following:

  • We will continue our long-standing record of powerful environmental reporting, known worldwide for its quality and independence.
  • We will report on how environmental collapse is already affecting people around the world, including during natural disasters and extreme weather events.
  • We will use language that recognizes the seriousness of the crisis we are in.
  • The Guardian will achieve net zero emission by 2030.
  • We will be transparent with our progress.

Previous studies have found that the increasing "roughness" of the earth's surface, from new buildings and urbanization, has acted as a buffer by slowing wind speeds to 2.3% each decade since the late 1970s. But recent research has shown that large volumes of ocean and atmospheric circulation can increase wind speed again.

The study showed that the main drivers of the world's wind speeds that accelerate world light were the Decadal Oscillation of the Pacific, the North Atlantic Oscillation and the Tropical North Atlantic Index.

Zeng said the effect of global warming on wind speeds remains largely uncertain because rising temperatures would have a diverse range of impacts that are not fully understood.

“We believe that our achievements in the study [the] an understanding of how climate change affects the wind, and we urge more scientists to focus on this important climate variable, "he said. "The study of wind can also shed light on the dynamic mechanisms of climate change."
