A: You have to start with situation analysis, for this purpose we are offering to you form of assessment criteria for international wind farm projects. download document
A: Wind turbines whisper quietly. Large, modern wind turbines have become very quiet. At distances above 200 metres, the swishing sound of rotor blades is usually masked completely by wind noise in the leaves of trees or shrubs.
A: Wind energy leaves no harmful emissions or residue in the environment. Wind Energy has a proven safety record. Fatal accidents in the wind industry have been related to construction and maintenance work only.
A: Wind energy is an ideal developing country technology. Although wind turbine design has become a high tech industry, wind turbines can easily be installed in developing countries, and serviced and maintained locally. Turbine manufacturers provide training courses for personnel. Installation of wind turbines provides jobs in the local community, and manufacturers will often manufacture heavy parts of the turbine, e.g. towers, locally once the installation rate reaches a certain level.
A: Wind energy is inexpensive wind energy has become the least expensive renewable energy technology in existence. Since the energy contents of the wind varies with the cube (i.e. the third power of the wind speed, the economics of wind energy depends heavily on how windy the site is. In addition, there are generally economies of scale when building wind parks of many turbines. Today, the energy cost to society (the social cost) per kilowatt-hour of electricity from wind is the same as for new coal-fired power stations fitted with smoke scrubbing equipment, i.e. around 0.04 USD per kWh for an average European site. R&D studies in Europe and the US point to a further fall in energy costs from wind of some 10 to 20 per cent between now and the year 2005.
A: Wind energy is clean, and saves energy. Wind turbines use only the energy from the moving air to generate electricity. A modern 1,000 kW wind turbine in an average location will annually displace 2,000 tonnes of carbon dioxide from other electricity sources, i.e. usually coal fired power stations. The energy produced by a wind turbine throughout its 20 year lifetime (in an average location) is eighty times larger than the amount of energy used to build, maintain, operate, dismantle, and scrapping it again. In other words, on average it takes only two to three months for a wind turbine to recover all the energy required to build and operate it.
A: Wind power is a rapidly growing market. Since 1993, growth rates in the wind turbine market have been around 40 per cent per annum, and growth rates of 20 per cent per annum are expected for the next ten years. Currently there are some 40 wind turbine manufacturers worldwide. Around half of the turbines in the world come from Danish manufacturers. In developed countries wind energy is mostly in demand because of its pollution-free qualities. In developing countries its popularity is linked to the fact that turbines can be installed quickly, and requires no subsequent fuel supplies. The wind turbine industry is now a 6 billion USD industry with an extremely bright future, particularly if environmentally friendly energy policies gain ground internationally.
