The number of patents for renewable energy technology has been on the rise, showing there is a lot of momentum in wind and other clean energy development, according to a new study.
The number of wind patents grew 19 percent annually between 2004 and 2009, the study showed. Wind, solar and other renewable power patents were exceeding 1,000 annually by 2009. Between 1975 and 2000, there were fewer than 200 patients for this technology, according to the report.
Jessika Trancik, an engineering professor at the Massachusetts Institute of Technology and co-author of the new study, said the uptick in renewable energy patents in the United States started taking off in 2000, USA Today reported. However, she said the Recovery Act initiated by President Barack Obama significantly helped spur research and development of renewable energy sources like wind in the U.S.
Renewable energy technology continues to expand, the source said.
“There's almost an unlimited amount of innovation, and we're seeing that through patents,” said Joel Makower, executive editor of GreenBiz.com
Innovation is being driven by demand, he said. Major businesses are investing in wind and solar to provide reliable power to data centers.
“This is not a warm fuzzy thing to do,” Makower said, according to USA Today. “This has become a business imperative.”
Google is one example of a company that has invested in wind and solar projects. The tech giant invested more than $1 billion in renewable energy projects that together are generating over 2 gigawatts of power, Forbes reported.
A large portion of a wind farm owner's operating and management costs comes from unplanned maintenance work on wind turbines. Broadwind Energy provides a comprehensive suite of uptower gearbox repair services, so wind farm owners can maintain turbine uptime to maximize profitability.
