Advantages and Disadvantages of Wind Power
By: James Nash | Posted: Aug 25th, 2008
Wind power, or wind energy, is a renewable resource; it is from the sun. The advantages of wind power are
many, including practical, environmental as well as economic. There are also disadvantages to using
windpower, such as the natural variability of wind, the competition for other land uses, and bird deaths.
Wind power, or wind energy, is a renewable resource; it is from the sun. The intensity of solar radiation
differs across the globe. Some areas receive intense amounts of sunlight, while others receive much less. The
result is a temperature gradient; a gradient which is mediated by the flow of air to and from areas of dissimilar
temperatures and pressure systems in our atmosphere. Uneven heating of the earth's atmosphere,
in addition to irregularities on the earth's surface and the rotation of the earth create wind. Terrain, water
bodies, and vegetation then shape flow patterns.
The recent history of wind power in the United States has a similar impetus to that of alternative fuel sources
in general - it was an idea borne from the 1970's Oil Crisis. It does, however, have a more extensive history
reaching back into to late 19th century in the colonization of the American West; millions of windmills were
erected for irrigation and cattle purposes to facilitate the growing number of farms and ranches. Many soon
feel into disrepair as inexpensive energy sources became more widespread and grid power extended its reach
into rural areas used small electric wind systems.
Outside of the US, however, wind power has a broader history. In fact, there was evidence that boats were
propelled along the Nile as early as 5000BC via wind energy. China used wind for pumping water several
Wind is harnessed to make mechanical power or electricity. The kinetic energy from the wind is converted
through various different processes to create mechanical energy that can be used in lieu of fossil fuels. There
are two types of modern turbi
