Tying Hydropower to Other Energy Forms
When we hear the term Asolar energy,” we usually think of heat from the sun=s rays which can be
put to work. But there are other forms of solar energy. Just as hydropower is a form of solar
energy, so too is windpower. In effect, the sun causes the wind to blow by heating air masses
that rise, cool, and sink to earth again. Solar energy in some form is always at work -- in rays of
sunlight, in air currents, and in the water cycle.
