Modification in the design of small wind turbine to increase power output

The global electrical energy consumption is still rising and there is an urgent demand to increase the power capacity. It is expected that power capacity has to be doubled within 20 years. The generation, transmission/distribution and use of electrical energy should be as efficient as possible. It has been found that if we save 1KW of energy at the end-user, 6KW is saved at the generation end. This calls for provision of incentives to save energy at the end-user. Deregulation of energy in the past lowered the investment in larger power plants, which establishes the need for new power sources in near future. Two major technologies play an important role to solve the future problems. (1) Use of renewable sources of energy. (2) Use of efficient power electronics in power generation, power transmission/distribution and end-user applications. This paper deals with one of the most emerging renewable sources, wind energy, which plays an important role in energy sector. With the use of proposed venturi tube design for small wind turbines proposed in this paper, the output of the wind turbine can be substantially enhanced.
