A discussion on renewable energy, focusing on the effects of global warming, has just released a feverish news.
By now, clean energy like wind farms is the key to tackling climate change. But recent studies show something very different. Global warming will significantly reduce the power of wind through the northern central latitude, including the United States, the United Kingdom and the Mediterranean. However, some places, including eastern Australia, will see strong winds. This is the first global study, talking about the effect of temperature increase on wind energy.
Research has found that there will be major changes by the end of this century in many places where a large number of turbines produce electricity. According to a new study published in the journal Nature Geoscience, future climate change could cause wind resources to drop across the Northern Hemisphere.
For example, in Central America, the power of wind can be reduced by almost one fifth. Although these findings do not exclude wind as a source of competition for renewable energy, the researchers suggest that energy planners take into account future climate when making long-term strategies for recycled energy. Wind power accounts for only about 3.7% of global energy consumption today, but global wind energy is increasing rapidly. It is increasing by about 20% a year.
In the most recent study, the researchers used a set of international climate modeling results to assess changes in wind energy resources around the globe. The team then used an energy curve model from the wind power industry to change wind, atmospheric density and global temperature projections to estimate wind energy production potential. .
Wind energy will take long from the center of the United States to Britain, Russia and Japan including countries with medium and high emissions. If carbon dioxide emissions continue at high levels, wind power could decrease in the latitudes of the center of the Northern Hemisphere and increase in the Southern Hemisphere and the tropics by 2100. Thus, climate change could affect global wind patterns. One reason is that the wind on the planet also receives varying degrees of solar radiation. The result is different levels of atmospheric pressure around the planet, affecting how air flows from place to place in the world. Therefore, scientists are well aware that global temperature changes can affect the airflow around the planet. This could have a big impact on the number of wind turbines that produce electricity. For example, the US Midwest has hundreds of wind farms with tens of thousands of wind turbines. New research shows that wind power production in the region for the next 20 years will be at the same level as it is today, but by the end of the century it will drop.
In contrast, the potential source of wind energy in northeastern Australia can increase significantly due to changes in temperature. However, the reasons for this decline and increase are not the same. Hotter temperatures in the Northern Hemisphere may also be due to the difference in temperature between the Northern cold region and the heat chain, and the lower temperature zone means that the wind is slower to operate in the central mid-latitude region. North. Similar reduced wind resources may occur in Japan, Mongolia and the Mediterranean by the end of this century. The reason coastal areas will see the increase in wind energy is that the world’s land is heating up faster than the ocean and the difference is that the energy for those winds to form exists. The warmer the soil, the greater the wind in that area.
The new research results will help policymakers around the world make informed decisions about where to invest in this clean energy technology.
