Wind energy is a clean energy. It is powered by wind turbines. Wind energy does not pollute the environment. If wind energy is powered its power gets stronger every second. A thick cable in the wind turbines collects wind energy and produces it into electricity. There’s also a general electric 1.5 megawatt machine that powers wind energy .big wind turbines are slow and small wind turbines are fast but big wind turbines are stronger because of the winds pressure so that’s why big wind turbines are stronger it can be as strong as 90 or 100 miles per hour.
