can meet all human needs. Solar energy has been used for generating electricity since
1954, Solar panels on the houses turn the energy of the Sun into electricity.
Another energy resource is the heat from inside the Earth: from volcanoes, gey-
sers, boiling pools. Several applications have been developed for this geothennal en-
ergy. For example, buildings and greenhouses can be heated by it. Hot water from
such sources is also used for heating soil to increase agricultural production. The
most important application of geothennal energy, however, is the generation of elec-
tricity. The first geothermal power station was built in Italy in the early 1900s. Since
then similar stations have been built in different countries. For example, San Fran-
cisco gets half of the energy from geothennal sources.
A great amount of electrical energy can be created by wind-powered generators.
It's only possible in windy areas. But, unfortunately, when there's no wind, no energy
is produced. In California, over 13,000 of these generators have been built.
The power of ocean waves can also be used to make electricity. And there might
be some other forms of energy we don't know anything about yet.

Unidentified Flying Object (UFO) is an object or optical phenomenon not ex-
plainable to the observer. UFOs became a subject of great interest with the develop-
ments in aeronautics and astronautics following World War II.
In 1948 the U.S. Air Force began collecting reports on UFO which started the
work called Project Blue Book. A number of radar discoveries together with what
people saw near the National Airport in Washington, D.C,, in July 1952, came to
forming a committee of scientists headed by H.P. Robertson, a physicist of the Cali-
fornia Institute of Technology (Pasadena), and including engineers, meteorologists,
physicists, and an astronomer. The Committee was organized by the Central Intelli-
gence Agency (CIA) and was concentrated on U.S. military activities and intelli-
gence. Its report was originally classified Secret. Later declassified, the report showed
that 90 percent of what was taken for UFO by the people who saw them could be
readily identified with astronomical and meteorologic phenomena, such as bright
planets, meteors, or with airplanes, birds, balloons, hot gases, and other phenomena.
The interest to the phenomenon grew in many countries and as a result a second
committee was organized in February 1966 which came to the similar conclusions.
This left a number of phenomena unexplained, and in the mid-1960s a few scientists
and engineers concluded that small percent of the most reliable UFO reports spoke of
the presence of the visitors from other planets.
This was a sensational hypothesis, which met opposition from other scientists. A
conference on this problem was organized in 1968 at the University of Colorado.
About 37 scientists wrote reports for the conference, speculating on the investigations
of 59 UFO phenomena in detail. Though at last it was declared that no more investi-
gation was necessary, the conference left a wide variety of opinions on UFOs.
In 1973 a group of American scientists organized the Center for UFO Studies in
Northfield, 111., to carry out additional work on these phenomena. However, there
