Wind Energy Benefits and Disadvantages

Cheap-ElectricityOne of the fastest growing sectors of renewable energy is wind power. Wind energy has been harnessed for many centuries. It has been used to mash grain to make flour, pump water, and more recently, generate electricity. When wind spins the blades of a wind turbine, a large magnet inside the top part of the tower spins inside of a cylinder of copper coils. The magnet passing by these coils generates an electric charge which is transmitted over power lines to the local energy grid. The primary benefit of wind energy is low cost renewable energy, but there is a little more to it than just that.

Wind energy is a true green energy source. Wind is powered by the sun, and generating electricity from wind emits no harmful pollutants into the environment. There is no consumable fuel source like coal or gas to use up, making wind power a renewable source of energy. Renewable energy means that the electricity generation can be sustained for very long period of time. While current estimates say that our oil and gas reserves will last about a hundred years or so, wind energy will be around long after that. Generating electricity from wind is really quite cheap, about four to six cents per kilowatt hour (kWh). They are primarily built in remote areas where winds tend to me the most consistent. You can see wind farms lining ridgelines, dotting the landscapes of plains or farms, or in some other countries, offshore.

That said, planning where to place wind turbines can be a challenge sometimes. Since most wind farm sites are in remote areas, extra infrastructure needs to be added to get the generated electricity to the grid that needs it. This means running long power transmission lines. Sites also need to be fairly consistent with the available wind. An area that gets very little wind will not be cost effective. Similarly, if winds are often too strong, the site will not be viable due to the risk of damaging the machinery. If a potential site for wind turbines has potential for other uses, the landowners will be taking other bids into consideration, thus determining what actual gets implemented.

While wind electricity generation emits no pollutants, it can still have an effect on the environment. There have been reports of increased bird deaths in locations where wind farms exist. However, the number of bird deaths per year is almost inconsequential compared to the number killed from catastrophic pollution disasters, such as the Deepwater Horizon oil spill in 2010. Noise pollution could be considered a problem for wind sites close to residential areas. The rotation of the rotor blades causes a constant whoosh-whoosh-whoosh sound that some residents may find bothersome. Others may not care for the sight of wind farms, claiming it taints their view.

All in all, wind energy has major benefits when it comes to generating cheap electricity, bolstering the economy, and cleaning up the environment. The challenges facing developers are reduced as technology improves. Newer turbines are quieter, for example. The Department of Energy wants to have 20% of the country’s energy produced by wind by the year 2030. This will expand manufacturing jobs, generate local revenue, conserve water, and even lower natural gas prices.
