Potential of vertical axis wind turbine in urban area

Abstract

Wind energy is one of the growing renewable energy sources. Usage is on the rise worldwide because of the cheap capital. It is used to produce electricity using the kinetic energy created by air in motion. A generator which is connected with a shaft produces electrical energy through electromagnetism. The trend of usage is also rising up in Finland. The amount of power which can be harvested increase each year. The scope of this thesis focused on determination of the potential of vertical axis wind turbine (VAWT) in urban area - turbulent flow area in which VAWT could be installed. Annual energy production of each VAWT was compared and evaluated for the effectiveness. Scope area was separated to urban area and neighbourhood area in a different hight level. QR6 turbine was found to be the most effective in VAWT. The capability of VAWT in the market would be increase further in the future due to the new technologies.
