Wind, an inexhaustible source of clean energy, is becoming more widely used at strategic level, rapidly gaining public support at the same time. Wind power has been used since ancient Babylon (wetlands drainage), Egypt (grain grinding) and China and Manchuria (pumping water from the rice fields) times. In Europe, this technology was introduced in the XII century, while the adoption of truly modern approaches started only in the XX century.
Wind power can operate in areas with wind speeds above 4.5 m/s level. Wind power stations can either conduct their business within a network of an existing plant or represent a stand-alone construction. The so-called ‘wind farms’, the areas where a number of pieces of wind collection equipment is concentrated and functioning as an entire system, are also gaining momentum due to noteworthy economic feasibility.
The greatest share of wind energy production belongs to the United States and Europe (Denmark, Germany, Great Britain and the Netherlands in particular). For long years the US has been holding the leadership among the most powerful wind plants in the world, Roscoe Wind Farm, generating impressive 781 MW of power. Another interesting example is Aeolus II wind farm that operates at Wilhelmshaven, Germany and produces 7 million kw/h of energy annually, providing about 2 million of households with electricity. Currently, there are nearly 23,000 active turbines installed in the world.
The ins and outs
Despite the mass production, the cost of construction of a modern wind power is still far from being affordable. However, it should be fairly noted that its operation cost is almost negligible. Environmental and economic benefits largely depend on the correct location; it requires a detailed and comprehensive analysis of both technical, environmental as well as financial aspects. Wind energy meets all the conditions necessary for its identity as environmentally friendly method of energy production. Its main advantages are:
- No pollution – the production of energy from wind neither results in emissions of harmful substances into the atmosphere nor entails waste generation.
- Wind power is renewable, inexhaustible source of energy, allowing to save on fuel consumption, as well as on the process of its production and transportation.
- The area in the vicinity of a plant can be utilized for agricultural purposes with no restrictions.
- Stable costs per unit of energy is produced, plus the method contributes into the growth of economic competitiveness in comparison with conventional energy sources.
- The minimum transmission loss of energy – wind power plants can be built directly by the consumer, and in remote locations, which in the case of conventional energy require special connection.
- Easy maintenance, easy installation, low maintenance and operating costs.
Cheap to maintain
Once the tiresome process of manufacturing and installing is accomplished, the only thing the company has to take care of is to initial regular equipment checks. So who are these guys? Normally, farm owners either have in-house engineers or cooperate with seasoned providers, such as Granada Material Handling, offering a full array of wind turbine services as well as provides assistance with wind turbine inspections.
