Show It is interesting to 'note that the United States has Today, by mechanical means we produce materials and goods with relatively small: expenditure of human energy. Today's farmer, for example, can now cultivate more land and produce g hand labor than before. more food with far less If all the machine power we now use in the United States had to be replaced by human energy, we would need 10.0 helpers for each man, woman, and child in the country.

The answer: our development of mineral pered at almost exactly the same rate as that at which its use of energy has increased. More than of the energy consumed in this country is provided by natural gas and petroleum. In the relatively short period of time since the steam engine was jterfected and since oil and natural gas were found in commercial quantities, the human race has made more material progress than during all the rest of its history. Machines driven by mineral energy have permitted greatly increased production of goods. These are not only the basic necessities, such as food, clothing,:and shelter, but the luxuries which our country en joys to a greater extent than any other. Because of mineral enerr, we are able to go from place to place by auto, ship, train, or plane in a tiny fraction of the time required by our grandfathers. All of this has resulted in steadily rising standard of living and know how to use' plentiful for the people that possess sources of mineral energy. two-thir- per-capi- ta back-breakin- great-grandfathe- rs ' " ' ! energy.
