EN FALLSTUDIE OM URBAN VINDKRAFT VID ALBANO
The use of energy is an important question in today´s society, and a substantial part of the energy that is used today is used in our homes. To lower this usage is vital, and there are regulations in place both on the national and the local level, that say that new apartment blocks must be built to consume less energy, which in the end will lower the impact on the climate.One way to make the housing sector more environmentally sustainable, is to produce energy issions that are bad for the environment, for example to build wind turbines close to or even on the buildings, so called urban wind power. The scope for this report is to see if urban wind power could be a sustainable alternative for the residential area that Svenska Bostäder plans to build in Albano in Stockholm.There are extensive scientific theories regarding wind and wind power, and a literature study is made to investigate past knowledge in the area. Efforts have been made to find earlier trials with urban wind power and, both scientific research and trials where urban wind power actually has been installed. The theory chapter deals both with the wind itself and how electricity can be generated from wind. There is also information regarding what laws apply when erecting wind turbines, and how the environment is affected by wind power.An analysis of wind data from nearby places is done, and from these results calculations have been made regarding how much electricity that two different wind turbines can produce over a year. The calculations show that with good wind circumstances, the smaller of the two wind turbines could produce 1 750 kWh in a year and the larger 5 240 kWh in a year. According to the economic analysis that is carried out, this would lead to a pay-off time of more than 250 years. From this it is concluded that wind power not is a viable option for Albano.
