Solar Energy vs Other Sources (Comparison) | Explained!

Solar energy comes from our nearest star, the sun, which sends us enough power in an hour to power our world for a year. Humanity uses this energy to heat homes, heat water, cook, and power home appliances, but will often require the solar power to be converted into a usable form first. This conversion is usually done using a solar panel system. Solar
