Keynote speech 2: Wind energy conversion systems (WECS)

Constantly growing demand for energy cannot continue indefinitely relies only upon fossil fuel. The earth´s finite supply will eventually exhaust. Energy is a major key to industrial development and the world´s well-being. The awareness of depletion of fossil fuel resources has challenged scientists and engineers to search for alternative energy sources that can meet energy demand for the near future. Recently the global warming, pollution and high oil prices forced politicians, utility companies (UC) and the general public to pay more attention to renewable energy sources (RES) such as wind, photovoltaic and bio fuels. RES are located right where the customers are, so they are used more efficiently, they are not polluting renewable and modular.
