Some people have concerns about the impact of wind turbines. As a result, many studies have been carried out and are available on Government and Industry association websites. Some frequently asked questions are as follows:
How strong does the wind have to blow?
Wind turbines start operating at wind speeds of 4 to 5 metres per second (around 10 miles an hour) and reach maximum power output at around 15 metres/second (around 33 miles per hour). In gale force winds (25 metres/second, 50+ miles/hour) wind turbines shut down to reduce unnecessary wear and tear.
Do the turbines affect birds and wildlife?
The greatest impact to wildlife is climate change, and wind energy is an important contribution to combating it. On a local level, we consult with organisations such as Natural England, Scottish Natural Heritage, RSPB and other environmental groups to ensure that wind farms have the least possible impact on wildlife.
Are they noisy?
No, modern turbines are quiet. Even if you were to stand amongst the turbines, a normal conversation could be conducted. As part of the development process we often arrange visits to wind farms for interested people in the local community.
