This invention relates to Vertical Shaft Wind Turbine which converts wind energy to electrical energy from 1 K. W to 100 K. W. It operates at low wind velocity/density. Vertical Shaft Wind Turbine consists of three turbine cups which are of unique feature to have least resistance to wind to rotate the turbine. The three cups of turbine which are placed alternatively at two planes with a shift of 600 angle shall make the turbine turn swiftly. It is easily adoptable and requires only a little space for fixation and operation. In Vertical Shaft Wind Turbine the weight of the total turbine is less than 30 % of any horizontal axis wind turbine which makes it convenient to install at any place. It can be fixed on top of the building as well as on the vertical edge of the building on the vertical axis.
