When it comes to wind energy, there’s a lot of hot air blowing around. Proponents and opponents alike are guilty of forming opinions without evidence, and energy analysis can often be more mystery than methodology. To help you weave your way through wind’s worth, here are 10 fascinating facts about wind energy.
