Wind Turbines Study
Among renewable energy types, wind is certainly becoming one of the most popular. While Germany pioneered the mass installation of solar energy, the UK has reached nearly 3 million megawatt hours, accounting for 13% of Britain’s totally electricity demand. This makes the UK the largest consumers of wind. However, wind power is not void of criticism. Some claim that wind turbines are noisy, costly, and have a low shelf life.
However, a new study by the Imperial College Business School claims that winder energy is far more productive than previously thought. After conducting a comprehensive analysis of the UK’s extensive turbine fleet and using local wind speed data from NASA, researchers concluded that the “UK’s earliest turbines, built in the 1990s, are still producing three-quarters of their original output after 19 years of operation, nearly twice the amount previously claimed, and will operate effectively up to 25 years.”
Better yet, wind turbines with newer technology seem to be out performing turbines with earlier technology. Now, turbines have 50% fewer moving parts and are constantly receiving hardware and software upgrades.
“There have been concerns about the costs of maintaining aging wind farms and whether they are worth investing in,” Professor Richard Green, co-author of the study, says, “This study gives a ‘thumbs up’ to the technology and shows that renewable energy is an asset for the long term.”
