Why is wind energy renewable

When these winds reach the west coast of Tasmania, they have blown across the cooling Southern Ocean for thousands of kms since last touching warm land on the tip of South America. What is wind energy? How does wind energy work? Wind power facts 1.

When was the first wind turbine built? What is the biggest wind turbine in the world? Is wind power a viable source for electricity demand? Today, many highly successful on-shore and off-shore wind power projects exist around the globe. Denmark - a producer and exporter of wind power Through clever planning, Denmark produces enough electricity to meet its domestic needs, as well as to export its excess energy to neighbouring countries.

Why is wind energy important? Wind energy is an extremely important and beneficial source of energy for several reasons: It is sustainable. The wind has been and always will be available to us. While certain days may provide more wind than others, it remains an infinite source of energy.

This means it guarantees longevity and will never run out. Utility companies can offer wind energy to homes that can help to hedge against uncertain fuel costs. This is a much safer option than fossil fuels, which fluctuate depending on resources and worldwide costs.

It leads to the creation of jobs. In , the wind industry supported , jobs across all states, plus Puerto Rico. As for future jobs, the U. Wind energy reduces the amounts of sulfur dioxide and nitrogen oxides that pollute the air when fossil fuels are burned.

It creates revenue, directly and indirectly. Over 99 percent of wind farms are in rural areas. As wind farms pay tax base in these areas, it creates new revenue to fix roads, fund law enforcement, and provides local jobs. It is cost-effective. Energy sources such as fossil fuels often fluctuate in price.

In contrast, wind energy is usually provided based on a fixed price over a long period of time, often around 20 years. Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. Wind turbines do not release emissions that can pollute the air or water with rare exceptions , and they do not require water for cooling.

Wind turbines may also reduce the amount of electricity generation from fossil fuels, which results in lower total air pollution and carbon dioxide emissions. An individual wind turbine has a relatively small physical footprint. Groups of wind turbines, sometimes called wind farms, are located on open land, on mountain ridges, or offshore in lakes or the ocean. Modern wind turbines can be very large machines, and they may visually affect the landscape. A small number of wind turbines have also caught fire, and some have leaked lubricating fluids, but these occurrences are rare.

Some people do not like the sound that wind turbine blades make as they turn in the wind. Some types of wind turbines and wind projects cause bird and bat deaths. These deaths may contribute to declines in the population of species also affected by other human-related impacts. The wind energy industry and the U. Most wind power projects on land require service roads that add to the physical effects on the environment. Producing the metals and other materials used to make wind turbine components has impacts on the environment, and fossil fuels may have been used to produce the materials.
