Those windmills spinning away in the hills and mountain passes provide clean and renewable energy to our power grids. Lawrence Livermore National Lab’s Julie Lundquist explains how wind turbines convert the forces of the atmosphere into electricity for our homes, businesses, and even cars. Explore how much power could be collected from the wind, how that amount compares to our demands, and how weather forecasts help wind turbines provide even more clean, renewable, and reliable energy.
