Q: What are the advantages of wind-generated electricity?
A: Numerous public opinion surveys have consistently shown that the public prefers wind and other renewable energy forms over conventional sources of generation. Wind energy is a free, renewable resource, so no matter how much is used today, there will still be the same supply in the future. Wind energy is also a source of clean, non-polluting, electricity. Unlike conventional power plants, wind plants emit no air pollutants or greenhouse gases.
Q: Are wind turbines very noisy?
A: Actually most turbine noise is masked by the sound of the wind itself, as the turbines only run when the wind blows. Noise from wind turbines has diminished as the technology has improved. Early-model turbines are generally noisier than most new and larger models. As wind turbines have become more efficient, more of the wind is converted into rotational torque and less into acoustic noise. Under most conditions, modern turbines are quiet.
Q: Is wind energy actually good for the economy?
A: Wind energy avoids many of the costs associated with conventional resources, namely, the trade deficit from importing foreign oil and other fuels, the health and environmental costs of pollution, and the cost of depleted resources. Wind energy is a domestic, reliable resource that provides more jobs per dollar invested than any other energy technology
Q: The wind doesn’t blow all the time. How much can it really contribute to a utility’s generating capacity?
A: In two separate studies researchers have found that despite its intermittent nature, wind can provide capacity value for utilities.
The studies, by the Tellus Institute of Boston and the Prince Edward Island Energy Corp, concluded that when wind turbines are added to a utility system, they increase the overall statistical probability that the system will be able to meet demand requirements. They noted that while wind is an intermittent resource, conventional generating systems also experience periodic outages for maintenance and repair.
Q: How do wind turbines work?
A: Basically a wind turbine works like a fan, but in reverse. Instead of using electricity to create wind like a fan, wind turbines use wind to make electricity. The wind turns the turbine’s blades, which spin a shaft connected to a generator which creates electricity.
Q: Do wind projects actually create jobs?
A: Yes, wind energy development creates long-term, high-paying jobs. Employees are required for wind turbine manufacturing, construction and installation, maintenance, operations, transportation, logistical services, and more.
