The World’s Largest Floating Wind Farm Is Already On Its Way

Share

For nearly 30 years, the world has been collecting renewable wind energy by installing giant wind turbines off shorelines, anchored to the sea floor. That surplus of wind power helps turn wind turbines. Converting wind’s kinetic energy into a renewable source of electrical energy for homes and business. Now, a new kind of floating wind farmRead More
