Wind energy's swift growth, explained (Update)
The wind industry is growing quickly around the world, and , where the total amount of electricity generated by wind turbines between 2011 and 2017.
All told, about now comes from renewable sources like hydropower, wind and solar energy.
As a , I realize it will be . Yet supports widespread predictions that the volume of wind energy will continue to grow quickly – here and abroad, on land and offshore – for reasons that most electricity consumers can support.
Rapid growth
Wind turbines, which convert moving air into electrical power, currently produce . in terms of the amount of power it gets from wind. of its electricity from wind turbines than any other state – 37 percent.
The U.S. still lags other nations, particularly those in Europe, with offshore wind production. But even on that front, the U.S. has seen growth. The , located off the coast of Rhode Island, began operating in 2016. plans to build a much larger offshore farm. And California may soon establish .
Some challenges
Wind is abundant, ubiquitous and free, but sometimes it dies down. Consequently, the energy from wind turbines can't provide power around the clock.
Recent improvements in energy storage technology and turbine efficiency, however, are and may potentially reduce the downside of wind's intermittent nature.
Today, wind power faces another challenge: politics. The Trump administration is sending mixed signals regarding the industry. It exited the Paris climate deal yet supports wind power growth as part of its "" policy.
Its advantages
Meanwhile, market forces coupled with widespread concerns over , continue to propel the wind industry. So is the enthusiasm from tech giants, such as and , which are proactively seeking to rely on wind energy, rather than fossil fuels.
And this wind rush is in manufacturing, services and science. With total generating capacity projected to increase from about 89 gigawatts to more than 400 gigawatts over the next 30 years, the Energy Department says the industry may eventually employ .
