Problems with wind turbines.
Collecting and Storing Energy from Wind Turbines. Due to the finite nature of non-renewable energy sources and the increasingly pronounced effects of climate change, securing alternative power sources is becoming a huge issue. One solution is wind turbines which convert the kinetic energy of the wind into electric energy for consumption.
A wind power class of 3 or above (equivalent to a wind power density of 150–200 watts per square metre, or a mean wind of 5.1–5.6 metres per second [11.4–12.5 miles per hour]) is suitable for utility-scale wind power generation, although some suitable sites may also be found in areas of classes 1 and 2.“The problem is the cost of building such a grid,” says Janusz Bialek, director of the Centre for Energy Systems at Skoltech Institute of Science and Technology.Advertisement.
