Pros & Cons of Wind Energy

Wind energy is an environmentally-safe alternative to non-renewable energy resources. Although wind-generated energy has pros and cons, it is reliable and proven. As exploration continues into the disadvantages of wind energy, consumers also weigh the merits of wind turbines for residential and commercial needs.

Significance

Fossil fuel energy resources are depleted and it use threaten the environment. Global climate change is the focus of a shift to renewable energy. The future is looking greener with the promises of nonrenewable resources on the near horizon. Wind power is green, leaves no carbon footprint and is in use now. It is one hopeful resource among a number of renewable energy possibilities.

Types

The main form of wind-generated power is by wind turbines, once called "windmills." Wind turbines convert kinetic energy into mechanical power that can drive generators, water pumps or other devices that require electrical power. Wind turbines have become technologically advanced, with important advantages over non-renewable energy resources.

Pros

Wind-generated energy is renewable and non-polluting. Wind turbines do not produce radioactive waste as do most ways of generating electricity. When the wind blows, wind power is a possible and proven technology. Access to wind is free and wind energy is not derived by fossil fuel-power. The initial cost of wind turbines is going down and will become increasingly affordable. All renewable energy resources offer the promise of new "green collar" jobs.

Cons

Wind energy has some disadvantages. Energy can be generated only when the wind blows. Backup power is expensive and must be replaced every few years. Wind turbines can be damaged in thunderstorms. There is a noise factor that increases when winds are low. Birds fly into wind turbines. Studies often are required about bird migration paths before new wind turbines can be installed.

Considerations

Weigh the pros and cons for wind-generated energy. Study the most likely regions to place wind turbines, based on atmospheric conditions. Wind renewable energy has proven advantages over oil, gas and coal. It is certain that the future of energy will include many renewable resources. While no single renewable is sufficient, there are a variety of renewables to complement what wind power offers.
