Wind Energy Text Version. Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind. Turbines catch the wind's energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor. A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade.

Wind Energy Threat to Birds Is Overblown Over the last few years, Bryce has been bashing wind energy in the pages of the New York Post, Wall Street Journal and other publications, charging that wind turbines are, among other things, ugly, noisy and a threat to public health. But what really seems to stick in his craw is their purported impact on birds.

Wind turbines have killed more birds of prey than persecution this year 5:25PM GMT 29 Oct 2014. Comments. Wind turbines have killed more birds of prey in Scotland this year, including a rare white tailed sea eagle, than deliberate poisoning or shooting, an official report has revealed. Four raptors were killed by turbines between January and June and a fifth bird, a golden eagle, was electrocuted by a power line. Over the same period, two birds were confirmed to have been poisoned or shot.

Wind turbine Efficiency can decrease slightly over time due to wear. Analysis of 3128 wind turbines older than 10 years in Denmark showed that half of the turbines had no decrease, while the other half saw a production decrease of 1.2% per year. Vertical turbine designs have much lower efficiency than standard horizontal designs.

- The output of a wind turbine depends on the turbine's size and the wind's speed through the rotor. Wind turbines being manufactured now have power ratings ranging from 250 watts to 1.65 megawatts (MW). Example: A 10-kW wind turbine can generate about 16,000 kWh annually, more than enough to power a typical household. A 1.65-MW turbine can produce more than 4.7 million kWh in a year--enough to power more than 470 households. The average U.S. household consumes about 10,000 kWh of electricity each year.

How does wind farm performance decline with age? By accounting for individual site conditions we confirm that load factors do decline with age, at a similar rate to other rotating machinery. Wind turbines are found to lose 1.6 ± 0.2% of their output per year, with average load factors declining from 28.5% when new to 21% at age 19. This trend is consistent for different generations of turbine design and individual wind farms.

Killer Kitties? Cats Kill Billions Of Creatures Every Year Researchers estimate that billions of birds and small mammals are killed by cats in the U.S. annually. The battle between cat lovers and bird lovers has been going on for a long time. Cats and birds just don't mix. But trying to get a handle on how many birds and other animals are being killed by cats isn't easy. Just figuring out how many cats there are is tough enough. Cats are really hard to count, says Pete Marra, an animal ecologist at the Smithsonian Conservation Biology Institute.

How Many Birds Do Wind Turbines Really Kill? But at least now there's a scientifically derived number for those deaths. One of the most commonly repeated criticisms of wind power is that it kills birds. The giant spinning turbines are basically bird death traps—and often they cut through prime flying space, making the carnage even worse.
