How much noise do wind turbines produce?
npower renewablesModern turbines are quiet in operation and you can hold a conversation underneath one without raising your voice. The final design of the wind farm will ensure that strict guidelines relating to noise are complied with.
Related QuestionsDo wind turbines produce low frequency noise?
BWEA - Frequently Asked QuestionsThere is always low frequency noise present in any ambient quiet background and it can be produced by a variety of man-made sources, including machinery and transport and natural sources such as the sea, wind and thunder.
Related QuestionsHow much of the time do wind turbines produce electricity?
BWEA - Small Wind and Frequently Asked QuestionsA modern wind turbine produces electricity 70-85% of the time, but it generates different outputs dependent on wind speed. Over the course of a year, a small wind turbine in the UK will generate about 20% to 30% of the amount it would generate in a constant strong wind. This is known as its 'load factor' (or 'capacity factor').
Related QuestionsTVA: Wind Turbine EnergyEnergy is generated when the wind speed reaches about 10 miles per hour, and a speed of 25 miles per hour allows the turbines to generate at their rated capacity. They shut down when the wind exceeds 55 miles per hour. Although wind speed varies according to the time of day, season, height above ground, and terrain, the proper placement of a wind turbine in a breezy location away from large obstructions enhances its performance.Related Questions
Do wind turbines present a health risk due to low frequency noise?
npower renewablesIt has been repeatedly shown by measurements of wind turbine noise undertaken over the past decade, and accepted by experienced noise professionals, that the levels of infrasonic noise and vibration radiated from modern wind turbines are very low; so low that they lie below the threshold of perception, even for those people who are particularly sensitive to such noise.
Related QuestionsDo wind turbines make noise or interfere with TV reception?
Canadian Wind Power Inc. Take Back The Power Solar, Wind, En...Small wind turbines do make some noise, but this is not a problem as long as the turbine is well-sited and located at least 200 metres from occupied buildings. Small wind turbines do not interfere with TV reception. See our Social, Environmental, and Other Considerations page for more details
Related QuestionsWhat do I need to know to purchase a residential wind turbin...Small wind turbines do make some noise, but not enough to be found objectionable by most people. A typical residential wind system makes less noise than the average washing machine. Wind turbines do not interfere with TV reception.Related Questions
Where are the wind turbines?
Montgomery County Residents: Help America Move Towards a Sma...We utilize windfarms across the Mid-Atlantic and the Midwest. The specific areas were chosen because the wind is so strong. And in many places, like the Appalachian Mountains, the local people are anxious to diversify away from the coal industry. Since the wind turbines take up so little actual land, the landowners can continue to use their property like they always have.

Frequently Asked QuestionsAll electric-generating wind turbines, no matter their size, are comprised of a few basic components: a rotor (the part that actually rotates in the wind), an electrical generator, a speed-control system, and a tower.Related Questions
Are wind turbines dangerous?
npower renewablesNo, wind energy is one of the safest energy technologies. No member of the public has ever been injured by wind energy or wind turbines anywhere in the world, despite the fact that there are now over 68,000 operational wind turbines.
Related QuestionsAre Proven Wind Turbines noisy?
FAQNo, they are specially designed to be suitable for installation close to people's dwellings. Proven Wind Turbines include special features to keep noise to a minimum. First the turbines work at low rpm - this is very important. The speed of the blade tips is the most important thing for wind noise - Proven Wind Turbines operate at around half the tip speed of some other turbines on the market.
Related QuestionsLarge modern wind turbines have rotor diameters ranging from 60 up to 100 metres; towers range from 60 to 100 metres in height. Hence the tip of the top blade can be anywhere from 90m to 150m above the ground. There are now prototype wind turbines 200m high, in Germany.Related Questions
Are wind turbines safe?
Wind energy is one of the safest energy technologies. No member of the public has ever been killed by wind energy or wind turbines anywhere in the world, despite the fact that there are now over 68,000 operational wind turbines.
Related QuestionsAre we likely to see more wind turbines?
Given the 15% target established for 2015, and the longer terms goals proposed by the Government, it is inevitable that renewable energy in its many forms is going to be an increasingly visible, necessary and familiar part of our world if we all wish to maintain our present lifestyles.
Related QuestionsDo wind turbines frighten livestock?
Wind farming is popular with farmers, because their land can continue to be used for growing crops or grazing livestock. Wind turbines do not disturb sheep, cows and horses. Delabole Wind Farm in Cornwall even houses a riding school.

Related QuestionsAre wind turbines noisy?
Desert Sky Wind ProjectThere is a "swishing sound" associated with wind generators, but with new turbine technologies, noise has been reduced as compared to older turbines. The Desert Sky site is in a rural setting some distance from homes. Our experience is that native and farm animals are not bothered by the noise from wind projects. The American Wind Energy Association has the following to say about noise, "Large, modern wind turbines have become very quiet.
Related QuestionsBANKS DEVELOPMENTS. DEVELOPMENT WITH CARE | Wind EnergyModern wind turbines are quiet in operation. They are designed for use in areas with low existing background noise levels. Well sited turbines should be quiet enough to cause no disturbance to people living a few hundred metres away. At these distances any noise from a turbine would be drowned out by the natural noise of the wind. Wind farms are designed taking in to account noise levels to ensure that local residents are not disturbed by their operation.Related Questions
