Energy exergy and economic assessments of wind turbine alternatives

Abstract

In this study two wind turbine installation alternatives for a residential district of 20 detached houses in six different European cities are considered. Firstly the installation of an individual residential scale (5 kW) wind turbine for each house is considered. Secondly the installation of a single wind turbine having the same total installed capacity (100 kW) is evaluated. The alternatives are compared according to annual energy production exergy efficiencies and simple payback time. The results pointed that the use of a single wind turbine is better that the use of individual residential scale wind turbines for small communities or districts.
