A conventional wind turbine is over 100 m high and produces more than 2 MW of electricity capable of supplying more than 2000 homesIt is necessary in this case to have a field to the height of these features which is the difficulty for the individual. But solutions exist and even if only a relatively low production, the use of wind energy can be interesting.
Wind: How it works
Man has been using since the dawn of time the wind. Renewable energy and available depending on the area and weather conditions, they may represent an interesting alternative. Many countries have already adopted this type of energy such as Denmark that uses this type of energy to meet 16% of its electricity needs.
The operation of a wind turbine or rather is based on a transformation of the kinetic energy of wind into mechanical or electrical energySo everything works by moving an air mass.
A wind turbine is composed of several elements, but whose work is influenced by the rotor blades which are attached and the electrical generator which is responsible for the transformation of the energy obtained by the movement of the blades.
Energy production is a function of wind speed. It may therefore happen that at times there is peak production or productions very low or no.
Wind turbines manufacturers are optimized to take advantage of medium strength winds that are most often short. This speed corresponds to wind speeds of 50km / h over, either internal or external stop or hinder the operation of the blades to prevent damage to equipment.
Wind turbines for individuals
Address the constraints and consumer demand, wind turbines for home use have been put on the market.
Easier to install, they certainly take up less space but suffer as a result a decrease in production. The importance of the surface to allow the installation depends on the size of the mast and weather conditions of the place of implantation. Know all the same as for efficient use, the distance is important.
A residential installation will produce an average of a few kilowatts for use for a few brief parts of a dwelling. However, it can be used to reduce its energy bill making it still an interesting ecological solution.
The domestic installation is subject to obtaining an administrative permit if the mast is over 12m. A lot of paperwork and procedures necessary to include the installation. The advice of local authorities, the direction of Public Works, Civil Aviation ... is required prior to carrying out the work.
The design ideas that installing this type of equipment produced some unpleasant noise around. While this is relatively true, builders and manufacturers improve their products to reduce the inconvenience. To be courteous to its neighbors, it is always necessary to inform them of the project. |
