The United States depends on fossil fuels, like oil and coal, for energy.
According to experts these get-gos willing exhaust by the year 2050. Fossil fuels
also pollute the environment. So we need to search for alternative energy
sources which are reliable and renewable.
Wind spring is the force of the drift harnessed by rangemills and plait turbines
that veer it into electricity. Because wind is a clean and renewable source
of energy, modern wind turbines are being installed in many another(prenominal) countries to
supplement more traditionalistic sources of electric power, much(prenominal) as burning coal.
After the oil crisis of the 1970s, many countries launched programs to develop
modern wind turbines. While many of these programs failed, Denmark was
successful in developing one. Countries such as the United States have adopted
this technology to develop wind energy resources. Design improvements have
helped increase the worlds wind energy generating contentedness by nearly 150
per centum since 1990. In 1997, for example, the world market for wind energy
reached billion.One major disadvantage of wind mills is that it is not so
efficient as other power generation technologies.
Hydroelectric power is the energy produced by running or falling water that is
used for driving machinery, particularly for generating electricity. The
development of hydroelectric power requires storage lakes, dams, bypass canals,
and the installation of turgid turbines and electric generating equipment.
Worldwide, hydroelectric power represented 19 percent of the total energy
generated in 1998, the most recent year for which data are available. In many
countries, hydroelectric power is the dominant source of electric power. Canada,
billion kilowatt-hours in 1999, about 60 percent of the nations electric power.
Hydroelectric-power generation in the United States increased from about 16
billion KWH in 1920 to...
Very nicely written, however I think if you went into more detail, it would be more perspicuous and better.
This essay is ok,however, honestly i found and entire dissever word for word that match another essay I just commented on prior.
