Not only in obvious ways, like the heating of the earth and water, but also in less direct or obvious ways. When the sun heats air masses they begin to move, which creates wind power. When the sun heats the oceans, water evaporates, enters the water cycle, and falls to Earth, feeding rivers and streams that can then generate energy. The sun's energy from millions of years ago is helping us today, too, in the form of fossil fuels. Long ago, the energy passed from the sun to plants and animals, and stayed in the plants and animals throughout their lifetimes.
