4 Million Wind Turbines Could Support About Half of 2030 Energy Demand

 1st Nov 2012

Wind energy could provide up to half the world's power supply with
little environmental impact, according to a new study by researchers
at the University of Delaware and Stanford University.

A feasible way has always been sought to power the world’s energy without harming the environment, studies show according to the University of Delaware, about 4 million turbines could provide the world with 7.5 terawatts of energy annually, about half of the estimated power necessary to run earth's power grids in 2030.

We've seen some papers out there that have been somewhat annoying or confusing because they had very low estimates of the total potential of wind energy. Science models have shown wind is very abundant, we feel very strong these previous studies were incorrect.

Sophisticated models, including one in which virtually the entire earth was covered in turbines, show whether or not Earth could support enough turbines to satisfy about half of the global power demand. The results say - yes it could.

About 4 million turbines would be an optimal number. The only problem being ­ the more turbines, the less energy the turbines could capture. Previous studies suggested that adding more turbines would create diminishing returns to a point where wind power wasn't worth utilizing.

Four million turbines is a lot, but it's not impossible. The benefits are immense, we'd have a clean economy and we'd be getting rid of pollution. If society wants to do it, the technology is there.

3% of all energy is generated with wind turbines in the United States, but the Department of Energy released a report in 2008 suggesting that by 2030, about 20% of America's energy could be generated by wind.

China has planned to order its electrical companies to source up to 15% of all of its power using wind turbines - a great effort for the environmental cause.

Unfortunately, Wind energy is a difficult nut to crack. With all of its draw backs in tow, it is difficult to see that the world could one day survive solely on energy generated by wind turbines.

Wind is not constant, sometimes it blows, sometimes it doesn't, there are reasonable concerns about wind power, and we're not saying it should be the only energy source.

With the world turning around a corner and walking into the unknown, Wind energy is a powerful resource that is there to be captured. All we need to do now -­ is harness it.
