Myth: Wind turbines spoil the landscape.

Fact: This is a matter of opinion. Compared to mountain top removal from coal mining, oil extraction, nuclear power plants and other energy developers, wind farms are quite elegant.

If we don't switch to cleaner forms of energy, climate change will severely and irrevocably alter much of our landscape as well as the animal and plant life it contains.  And in the United States, over 24,000 people are dying prematurely each year because of dirty power plant pollution - we obviously need to change our energy sources fast, and wind provides a clean, safe alternative.

Myth: Wind turbines threaten bird populations.

Fact: Studies show that for every 10,000 bird fatalities, less than one is caused by wind turbines. For comparison, cats cause about 10 percent of bird deaths and nearly half are caused by collisions with buildings or windows.

In fact, a recent study published Intergovernmental Panel on Climate Change shows that 40 percent of all species could face extinction because of global warming.

Monitoring of existing wind farms suggests that with proper location and construction, there is no adverse impact on bird populations.  

It's important for wind farms to conduct a thorough analysis of the risk to bird life as part of the environmental impact assessment of every proposal. With rigorous review, thorough monitoring, and sensitive design, wind power can be deployed without significant harm to birds (and other wildlife).

Myth:  Tourists hate wind farms.

Fact: There is no evidence to suggest that wind farms deter tourists, indeed many wind farms are actually tourist attractions.

For example, in Swaffham, Norfolk, over 50,000 tourists have climbed the wind turbine tower to see the spectacular views from the top of its the 214-foot high viewing platform

In Denmark, many tour agencies run boat trips to take visitors to see the offshore wind farm at Middelgrunden, near Copenhagen.

Here at home, the wind farm in Searsburg, Vermont consistently fills educational tours of its facilities almost as soon as they are announced.  

Myth: Wind turbines are noisy.

Fact: Modern turbines are actually very quiet! Thanks to advances in wind turbine technology, well designed, well-sited turbines can be quiet enough to cause no disturbance to people living just a few hundred yards away.

At these distances, any noise they do make is usually drowned out by the natural noise of the wind itself in the trees and vegetation. To protect nearby residents from any undue disturbance, proposals to install wind turbines are required to meet strict noise standards.

Having read exaggerated claims in the press, people visiting wind farms are often surprised at how quiet they actually are.

Myth: Wind power isn't reliable.

Fact: Yes it is. There is actually a lot of confusion about the reliability of different sources of electricity. No power stations are able to operate all the time. Many so-called reliable sources such as nuclear plants suffer from unexpected "outages" when reactors must be shut down, often at short notice, for essential safety maintenance.

Unreliability of this kind is far harder to deal with than the intermittence of wind power, as the amounts of electricity involved are generally much higher. By comparison the variation in output from wind farms distributed around the region is scarcely noticeable.

In future, hydrogen offers a potential way of storing electricity from wind power. Excess wind power can be used to produce hydrogen through electrolysis, and then hydrogen can be turned back into electricity using a fuel cell when it is needed.
