Because the wind energy is also the source of the clean‚ and non- polluting‚ electricity. Wind energy is friendly to the surrounding environment‚ as no fossil fuels were to generate electricity from wind energy. Wind Energy is a viable industry that has become energy source. The energy generated from wind is clean and efficient. The wind energy industry

WIND POWER (RENEWABLE ENERGY) IN PAKISTAN By The wind of change is blown and world has now emphasizing towards new technologies out of which renewable energy is important one. Keeping in view the commercial and industrial consumption of oil and gas everyone is conscious to have some alternate resource for energy production. Wind is also one of the resources for the power generation. A wind turbine is a device that converts kinetic energy from the wind‚ also called wind energy‚ into mechanical

“A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy”. (1) The inventor of the first electric wind turbine was Clevelander Charles Brush‚ who ran his entire Euclid Avenue mansion off of one for 20 years‚ which later made the cover of Scientific American in 1888. (2) Although the use of alternate energy didn’t rise a great deal afterwards‚ this event did open the eyes for many environmentalists. Wind power is only one of our several “energy source[s] whose

Background/History on the Wind Power Industry The wind power industry first developed in Iran around 200 B.C. The first windmills were vertical axis wind turbines‚ which were used for pumping water and grinding whole grains for food consumption. The Chinese‚ Romans and Afghans all used windmills around this time for similar use. In the 13th century Holland started developing large horizontal axis windmills. These four-blade windmills were larger‚ carried more torque and wind speed and could do more
