WIND ENERGY
WIND ENERGY- AVAILABILITY AND APPLICATIONS Coal, gas and oil will not last forever. So renewable are expected to play a key role. Wind energy is the fastest growing renewable. Wind turbines are up to the task of producing serious amounts of electricity. Turbines vary in size from small 1 kW structures to large machines rated at 2 MW or more. In future, fossil fuels are likely to reach their maximum potential, and their price will become higher than other renewable energy options on account of increasingly constrained production and availability. Therefore, renewable are expected to play a key role in accelerating development and sustainable growth in the second half of the next century, accounting then to 50 to 60% of the total global energy supply. ...
