Solar energy power from the sun is a vast and inexhaustible resource. Once a system is in place to convert it into useful energy, the fuel is free and will never be subject to the ups and downs of energy markets. Furthermore, it represents a clean alternative to the fossil fuels that currently pollute our air and water and threaten our public health. Given the abundance and the appeal of solar energy, this resource is poised to play a prominent role in our energy future.
In the broadest sense, solar energy supports all life on Earth and is the basis for almost every form of energy we use. The sun makes plants grow, which can be burned as “biomass” fuel or, if left to rot in swamps and compressed underground, in the form of coal and oil. Heat from the sun causes temperature differences between areas, producing wind that can power turbines. Water evaporates because of the sun, falls on high elevations, and rushes down to the sea, spinning hydroelectric turbines as it passes. But solar energy usually refers to ways the sun’s energy can be used to directly generate heat, lighting, and electricity.
