Wind energy is a clean, renewable source of energy. Only 1% of the total wind energy available is enough to fulfill all global energy needs, meaning wind is a potential source of an enormous amount of energy. The main drawback to wind energy is that it is noisy, intermittent, and to some unsightly. Other disadvantages cited are potential danger to birds, which may result in changes in migration patterns of some bird species, and shadow flicker – when moving blades cast shadow on nearby residences. However, wind turbine technology is undergoing rapid development: new composites have allowed substantial weight reduction, turbine noise is continually reduced, and new manufacturing technologies have allowed larger and larger blades-- making construction of multi megawatt turbines possible. At present, the average cost of production of electricity from wind energy is slightly higher than that from fossil fuel, but as demand for energy increases and fossil fuel sources deplete, the cost is rapidly becoming competitive with or even cheaper than those of nonrenewable sources of energy. Wind energy is expected to be a major energy source for most developing and island nations, as well as many developed European countries in the 21st century.
