Wind farms generate electricity using windmills or turbines and are popular in countries focusing on alternative energy. They are considered a “green” form of energy, although resources are required for setup. Wind farms can take up space and pose a threat to migratory birds, but are generally environmentally sound and fiscally viable.
A wind farm is a set of windmills or turbines that are used to generate electricity through their mechanical movements while being propelled by the wind. Both Europe and the US have large numbers of wind farms, and the technology is found on other continents as well. In Asia, India in particular has devoted a large amount of funds to the establishment of such farms. The energy generated by these farms can be fed directly into the general energy grid after passing through the transformers.
As a potentially large source of renewable energy, wind farms are especially popular in nations that are focusing on alternative energy. Other types of renewable energy include wave energy and solar arrays. All of these technologies take advantage of the energy that already exists, converting it into a usable form. Because a wind farm does not actively deplete resources while generating power, it is considered a “green” form of energy.
Of course, some resources have to be spent on setting up a wind farm. The turbines, transformers and grid system on a farm are often made from non-ideal substances, such as uncleanly mined metals. However, once installed, the company requires no additional energy production beyond that required for basic maintenance. This is a stark contrast to a power plant that relies on coal or petroleum products.
Naturally, the best location for a wind farm is a windy location. In some cases, a windy place can also be generally unusable or uninhabitable. In other cases, a wind farm may occupy useful real estate that could be used for agriculture. This has led to some criticism of these farms, as they take up much more space than a comparable non-renewable energy production plant. Furthermore, these farms pose a serious threat to migratory birds, as has been clearly documented by several scientific organizations.
Aside from these issues, the technology is generally believed to be environmentally sound and fiscally viable. Especially if farms are combined with other renewable energy sources, green energy could make up the majority of the electricity grid. This could have a huge impact on the environment and society in general. Especially in the late 20th century, when growing numbers of citizens began demanding energy reforms, wind farms held great promise.
