Solar thermal (heat) energy is a carbon-free, renewable alternative to the power we generate with fossil fuels like coal and gas. This isn't a thing of the future, either.
Solar energy is the cleanest, most abundant renewable energy source available. The U.S. has some of the worldâs richest solar resources. Today's technology allows us to harness this resource in several ways, giving the public and commercial entities flexible ways to employ both the light and heat of the sun.olar energy is the cleanest, most abundant renewable energy source available.
