Wind is technically a form of solar energy. When the sun's radiation heats Earth's uneven surface, hot air rises and cool air settles. This difference in atmospheric pressure creates wind, a kinetic (motion-based) form of energy. Wind turbines capture that kinetic energy. When wind. Solar energy is the sun's radiation that reaches Earth. When sunlight hits the photovoltaic (PV) cells inside solar panels, these cells transform. Which sustainable power source makes more sense for local and state economies? Check out this infographic that compares the good and bad of wind and solar energy.
