Yes. The wind power is already profitable. It is the fastest growing form of renewable energy. Wind power has a very bright future ahead. According to recent a study, it has been found that wind power can easily meet the demands of the entire world. Seventy two terawatts of wind power can be obtained throughout the world.

The current global demand for energy is about 15 terrawatts. This means that wind energy can provide more than 4 times the current global demand. Wind power is renewable, clean, eco friendly and has low maintenance cost. It has an advantage which solar doesn't. Solar power is not available 24 hours and is also very expensive initially. Wind power will easily reduce foreign dependence of oil if invested and harnessed the right way. Oil has a very bleak future.

The current oil reserves would last at the most till the end of this century. Peak oil has already gone past its limits. Oil is becoming scarce and expensive. It is dirty and not eco friendly. All these factors give wind energy a huge advantage.

According to the Union of Concerned Scientists (www.ucsusa.org), wind power is expected to become a profitable industry. By 2020, about 5% of the nation's electricity is expected to come from wind energy. Individuals can purchase their own wind plant, and although it may seem like an expensive investment, it can produce your own energy for up to 30 years, saving you a lot of money on the electric bill.

Wind power is already a profitable industry. The cost of wind energy is comparable to that of energy produced by coal- or oil-fired power plants. Wind power can greatly reduce the dependence of a country on foreign oil.
