If prices for oil and gas fall, wind energy will lose significant demand. The demand for Suzlon's products arer correlated with the price of oil, making the company relatively dependent on the state of the fossil fuel market. From July to December 2008, crude oil has fallen 64 percent from a record $147.27 to about $53 a barrel. Since wind energy is a substitute for petroleum, a decrease in price of oil will result in a decrease in demand for wind energy.
