One of the most important economic benefits of wind power is that it reduces the exposure of our economies to fuel price volatility. This benefit is so sizable that it could easily justify a larger share of wind energy in most European countries, even if wind were more expensive per kWh than other forms of power generation. Wind energy costs-coverThis risk reduction from wind energy is presently not accounted for by standard methods for calculating the cost of energy, which have been used by public authorities for more than a century. Quite the contrary, current calculation methods blatantly favour the use of high-risk options for power generation. In a situation where the industrialized world is becoming ever more dependent on importing fuel from politically unstable areas at unpredictable and higher prices, this aspect merits immediate attention.
The theoretical potential for wind, as estimated by the global annual flux, has been estimated at 6,000 EJ/yr. The global technical potential for wind energymeanwhile,Technical potential is not fixed, but is instead related to the status of the technology and assumptions made regarding other constraints to wind energy development. Nonetheless, a growing number of global wind resource assessments have demonstrated that the world’s technical potential for wind energy exceeds current global electricity production, and that ample technical potential exists in most regions of the world to enable significant wind energy deployment relative to current levels. 
Wind energy, used by civilizations for thousands of years to grind grain and pump water using windmills, was reborn during the energy crisis of the 1970s when improvements in materials and technology made wind turbines more common. Today, windgenerated electricity is helping to provide for U.S. electrical needs. 
Windmill coverWind is created when solar energy heats the atmosphere. This heat produces differences in air pressure as cold air is denser than warm air. Air is made of gases and gases will naturally move from an area of high concentration to an area of low concentration to equalize pressure differences (reaching an equilibrium), creating wind as a result. In the process, energy from the sun is converted into kinetic energy (the energy in motion).
Wind energy is a form of solar energyWind is caused by the uneven heating of the atmosphere by the sun, Wind energy characteristicsvariations in the earth's surface, and rotation of the earth. Mountains, bodies of water and vegetation influence wind flow patterns. Wind speeds vary based on geography, topography and season. As a result, there are some locations better suited for wind energy generation.  Wind energy is a special form of kinetic energy in air as it flows. Wind energy can be either converted into electrical energy by power converting machines or directly used for pumpng water, sailing ships, or grinding gain.
Wind power is the fastest-growing source of electricity worldwide. The American Wind Energy Association estimates that more than $40 billion will be spent worldwide over the next decade to build new wind installations.
Clean wind energy
The opportunities for industries that build, buy, or invest in wind energy are tremendous. Nowadays, the global environmental crisis is receiving more and more attention, and the utilization of clean energy has become a major issue in promoting sustainable development. Among the various energy sources, wind power generation system has its unique advantages. In this article, we will list a few of the major benefits that wind energy can bring. 
Wind energy is a universal resource. Energy debate coverIt can satisfy a multitude of global energy problems not only theoretically but also in actuality.
 It can be used to generate electricity, the leading source of energy of the twenty-first century. From the finite nature of fossil fuels, their geographically uneven distribution, and the resulting climate change due to its burning, to the dangers of the nuclear sector, recently experienced so dramatically in Fukushima, these problems are increasingly being answered through the generation of electricity by means of regenerative sources, especially with the use of wind energy.The international energy debate reached a new dimension with the publication of Meadows'Limits to Growth, the report of the Club of Rome.
Wind energy is a form of solar energy. Earth’s atmosphere is unevenly heated by solar radiation and the air is in constant motion to find equilibrium. Wind energy harvest coverAir is easily affected by pressure and temperature so methods of heat transfer such as convection, conduction, radiation, and advection relieve the temperature imbalances and are driving forces for wind. Wind is an intermittent source of energy with many factors affecting wind flow patterns, such as geological features of Earth’s surface, bodies of water, vegetation, and the Earth’s rotation.Wind is harvested through wind turbines, which generate electricity by converting the kinetic energy of the wind into mechanical energy.
The kinetic energy in the wind is a promising source of renewable energy with significant potential in many parts of the world.
 The energy that can be captured by wind turbines is highly dependent on the local average wind speed. Regions that normally present the most attractive potential are located near coasts, inland areas with open terrain or on the edge of bodies of water. Some mountainous areas also have good potential. In spite of these geographical limitations for wind energy project siting, there is ample terrain in most areas of the world to provide a significant portion of the local electricity needs with wind energy projects (Rangi et al., 1992).
