Kevin Hand of The Wall Street Journal outlines how wind turbines have become more efficient.
- Technological innovations have made wind turbines more efficient.
- Wind turbine blades for instance have grown from 26 feet in length to an average of 351 feet in length.
- In 1980 a majority of turbines were made with fiberglass- today they are made with carbon fiber which has made them lighter and more efficient.
“A key improvement has been modern blades that are far more sophisticated in design, from aerodynamic properties to materials. This has enabled a variety of other improvements to the turbine, including greater size and more height (which means the turbine can tap higher wind speeds), with less noise.”
