    Wind: the wind could satisfy the world energy demand

    The energy produced by the wind could satisfy the needs of the entire planet, but on one condition

    Wind power, the energy produced by the wind it could meet the needs of the entire planet. The researcher is sure of it Kate The Marvel movies of Lawrence Livermore National Laboratory, in California, but on one condition: the turbines will have to be placed at a high altitude.





    The wind could potentially have the power to power the earth and its need for energy, but it is unlikely that it will really have a substantial impact on the climate. Calculations in hand, even considering the maximum levels of energy production, there would be no substantial effects on the planet's climate as long as the turbines they will arise at low altitudes and in a number of limited areas of the Earth. As things stand, wind could affect surface temperatures by about 0,2 degrees Fahrenheit and affect rainfall by about 1 percent. Overall, the environmental impact would not be substantial.

    This is the opinion of the experts of the Lawrence Laboratory. But the wind can become one primary source of electricity almost zero emissions all over the world. How? Wind turbines will need to be installed at high altitude. Today, according to experts, wind power cannot change the fate of energy but it would be enough to introduce this novelty. Using a climate model, Kate Marvel, lead author of the study, along with colleagues Ben Kravitz and Ken Caldeira of the Carnegie Institution Department of Global Ecology, estimated the amount of energy that can be produced by winds near high altitudes. The team found that wind turbines on the surface could extract kinetic energy at speeds of at least 400 terawatts, while at high altitudes wind power could extract more than 1.800 terawatts.

    Because? Above, jet streams are typically more stable and faster. "We have shown that equivalent amounts of extracted energy have different consequences for the Earth's climate and circulation in general whether obtained on the surface alone or throughout the atmosphere," Marvel said. Solved the 'technical' limit, according to experts, theAeolian however, it will not have an easy time given that "it will probably be determined by economic, political and technical constraints rather than by geophysical limits".



    The study was published in Nature Climate Change.
