5. Technical & Economical Feasibility Micro Wind Turbines Conversion of wind energy into useful energy using micro wind turbines Power Output (W) = 0.5 × Swept Area × Air Density × Wind Speed 3 65000MW Solar Energy Use of photo-voltaic devices to generate electricity Continuous supply & storage of power is made possible 5000 trillion kWH Fuel Cells Utilizes the reverse hydrolysis process wherein H2 combines with O2 to produce electricity and produces water and heat as by-products Back up power in order to ensure consistency of power supply Device Description End-use Size 5000 trillion kWH Combination of Wind, solar & Fuel cells Optimal combination of all the three is decided by HOMER which ensures optimum usage of the available resources Consistent power supply to BTS stations at reduced cost Telecom operators market tapped + + = ©b rahm&company ©b rahm&company © b rahm&company
