to heat systems directly. Wind energy can be captured using wind turbines, which turn
generators to produce electricity. Hydroelectric energy can be produced by using the
energy of running water to turn generators.
Although all types of alternative energy resources have various advantages and
disadvantages, these three all share the advantage of not producing air pollution
Hope this helped. :)
