Text I.
New Energy from Old Sources
The resources of fossil fuel formed over a period of 600 million years
made the industrial revolution possible and have added to the comfort and
convenience of modern life. We will consume them in a few hundred years at
current rates.
The current energy problem is the result of many complex and
interrelated factors, including a world-wide demand for energy, inadequate
efforts during the recent past to develop new energy resources, delays in the
construction of nuclear power plants, automobile changes that increase gasoline
consumption.
Demand must, of necessity, be moderated, and intensive efforts must be
made to expand the overall energy supply.
But energy is available to use in practically unlimited quantities from
other sources. Large amount of energy can be received from ocean tides and
currents, form huge underground steam deposits, from the power of the wind
and from the heat of the Sun.
The idea of heating houses with the warmth of the Sun has become
popular in the last few years. Since the U.S. News and World Report first told
about solar heated homes near Washington, many similar projects appeared
around the country. In many places schools are using solar units to provide
classroom heat.
Most solar-heating systems coming on the market use a black surface to
absorb the Sun’s heat. Engineers cover the surface with glass which lets in the
rays, but holds heat. The heat transferred to water runs through small pipes. The
hot water is then circulated through the house.
The solar cell is another way of producing power from the Sun. It
converts sunlight directly into electricity. These cells are used with great success
in the space program, but remain far too expensive for widespread application.
In the meantime, solar homes are being built and lived in. The next step
is mass production of homes, office buildings and schools – all heated by the
Sun.
Putting the wind to work researchers are showing great interest in the
age-old windmills. Several big companies are now studying windmills. These
companies are to analyse windmills ranging from 100 to 2000 kilowatts. The
smallest would provide sufficient electricity to power several homes, the largest
could provide electricity to a small village
