Nuclear Energy
Nuclear energy is an efficient and convenient substitute for conventional forms of energy which were found in special geographical locations. Large amounts of
(51) and effort are required to
(52) these locations. Once the sites are found, men and equipment must be brought to tap and use these sources of energy. However, a large proportion of such sites are found only in far and
(53) places. This increases the difficulties of
(54) these forms of energy. With nuclear energy, such difficulties are not present. Nuclear reactors can easily be built anywhere, and man does not have to compete with the
(55) of nature in order to obtain the energy. For equal amounts of energy, nuclear energy is much more convenient and inexpensive to obtain than conventional sources of energy.
With nuclear energy, the amount of pollution is greatly reduced.
