Excerpt from Solar Energy and Its Use for Heating Water in CaliforniaPractically all the energy on the earth's surface has sunshine as its primary source. Hydroelectric energy is obtainable because sunshine promotes evaporation of moisture, great masses of air containing this water vapor circulate so that water from low levels is carried back to higher levels, constantly replenishing the lakes and rivers. Wood and agricultural products used for fuel cannot grow without sunshine, and coal and petroleum are the concentrated carbon products of age-old plant and marine life that used the sunshine of past geologic time.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
