A big flap over wind power

One of the biggest complaints against wind turbines is that they kill birds. Initially, this threat was a serious problem because builders didn't take bird and bat migration routes into consideration when erecting the turbines. A report put out by the U.S. National Academy of Sciences says that for every 30 wind turbines, one bird is killed each year, although these numbers are contested. Based on these numbers, 40,000 birds die because of wind turbines each year in the U.S. alone.

While wind energy moves forward, wind turbine developers and companies are taking concerns for bird safety into account. They usually build turbines away from migration routes and often add colored markings to the blades to ensure that our feathered friends can see them. Ultimately, wind turbines are far from a bird's worst enemy, making up just 0.003 percent of human-caused bird deaths in the U.S.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
