The protocol of Kyoto, signed by 180 States in 1997, was penned under the aegis of the United Nations, and engaged 38 industrialized countries to reduce their gas emissions between 1990 and 2010. The ratification of this protocol created a situation where the necessary control of the carbon dioxide emissions (CO2) will lead the signatories of the industrialized countries to reinforce their environmental policies. This is why, since 1990, the renewable energy and, in particular solar energy and electricity produced from wind experienced a significant development. The surveys estimate that 10% of European energy will be sourced from the wind.

Renewable energies represent the energy whose consumption does not lead to the reduction in the natural resources, because it draws from elements that are recreated naturally. Provided by heat, wind, water, tides and the growth of the plants and the recycling of waste, their exploitation does not generate waste nor does it pollute the atmosphere. One characterizes renewable energies as the flow of energies compared to the stock of energies that consisted of limited fossil fuel layers that comprise oil, coal, gas and uranium. In France, one estimates that 8000 wind mills will be established in the territory in the year 2010. This ambitious project thus leads us to ask the following question: is it necessary to invest in wind energy? First of all, we will analyze the reasons that push us to invest in this energy and then, examine if this investment is free from dangers.

Today, wind energy gains acceptance in the minds of French consumers because of the willingness of governments to protect the environment or to use renewable energy to address concerns of excessive pollution. It is therefore interesting to know what the real interests of the use of wind energy compared to the inconvenience it causes. As for the benefits of wind energy, it is important to emphasize that this energy is renewable, natural, and some players such as municipalities, owners of agricultural land or even households can benefit from the implementation of wind turbines.

Wind power uses wind as an inexhaustible source of energy, unlike fossil fuels (oil, coal, natural gas) or fissile (uranium) fuels used in power plants or nuclear weapons. Wind energy is clean energy par excellence. Indeed, a wind turbine produces no pollution of the soil (no production of soot, ash, waste), no water pollution (no release to the aquatic environment, lack of production of heavy metals), no air pollution (no greenhouse gas emissions, dust, fumes, odors, gases, nothing which promotes acid rain). Moreover, it is a free source of energy and abundant in our country, strengthening our energy independence vis-à-vis the oil producing countries or natural gas, the hydrocarbons being expensive today. Finally, it allows to fulfill the commitments made at the signing of the Kyoto Protocol.

Wind energy is the energy from the wind using a wind turbine device as a windmill.It takes its name from Aeolus, the name given by the Greeks to the god who was supposed to produce the wind.
