Wind why Why: the case for wind power It’s clean. Wind power is non-polluting and safe. During operation it does not contribute to global warming. There is no legacy of pollution for future generations. In contrast brown coal‚ the main source of Victoria’s electricity production‚ is the most polluting of the fossil fuels‚ making this state the worst greenhouse polluter in Australia. If we are to avoid climate change we must drastically cut emissions. It’s affordable and available right now

Wind is an important source of non-conventional energy which is cheap‚ pollution-free‚ environment friendly and can be developed away from the sources of conventional energy. This energy was utilised in sailing ships and wind mills since ancient days. In India the generation of electric power through wind mills started in 1950 and by March 1993 about 2‚900 wind pump sets has been installed in seven states of the country. At the beginning of the Eighth Plan the installed capacity of wind-based

Renewable Energy Wind Abstract We have been harnessing the wind’s energy for hundreds of years. From old Holland to farms in the United States‚ windmills have been used for pumping water and grinding grain. Today‚ the windmill’s modern equivalent‚ a wind turbine‚ can use the wind’s energy to generate electricity. Wind turbines can be used as stand-alone applications‚ such as for pumping water or to help reduce homeowners’ electric bills‚ or they can be connected to a utility power grid

Flying Wind Generators Flying wind generators are the future of wind energy. This article talks about the replacement of wind turbines for “windmills in the sky”. Instead of using the current wind turbines‚ Bryan Roberts‚ and engineer at University of technology in Sydney‚ Australia‚ decided to fly wind turbines into the jet stream 15‚000 to 45‚000 feet into the sky with winds up to 200 miles per hour. With 600 of these producing 20 megawatts each could power two Chicago sized cities. The

| | ADVANTAGES OF WIND POWER: | | | 1. The wind is free and with modern technology it can be captured efficiently. 2. Once the wind turbine is built the energy it produces does not cause green house gases or other pollutants. 3. Although wind turbines can be very tall each takes up only a small plot of land. This means that the land below can still be used. This is especially the case in agricultural areas as farming can still continue. 4. Many people find wind farms an interesting feature

The most renewable source of energy in Ireland is wind power. Ireland is a small island country situated at the very north west of Europe where the resource of wind is abundant. At 50 meters above ground level at all the 5 main points open plain‚ open sea‚ sea coast‚ hills and ridges and sheltered terrain Ireland has a significant amount of wind and wind resource which increases the potential for renewable energy generation. All this free wind could power schools and homes throughout Ireland.

Advantages and Disadvantages of Wind-Generated Electricity A Renewable Non-Polluting Resource Wind energy is a free‚ renewable resource‚ so no matter how much is used today‚ there will still be the same supply in the future. Wind energy is also a source ofclean‚ non-polluting‚ electricity. Unlike conventional power plants‚ wind plants emit no air pollutants or greenhouse gases. According to the U.S. Department of Energy‚ in 1990‚ California’s wind power plants offset the emission of more than 2.5

The Cumberland News Wind Farms in Cumbria The majority of the world uses non-renewable sources of energy for electricity and this is having a negative impact on the world. Fossil fuels generate most of our electricity but by using them‚ we create greenhouse gases while combusting them. Hence this contributes to global warming and is impacting the rest of the world. If the level of greenhouse gases keep on rising‚ the earth will get warmer; sea levels will rise and droughts will occur throughout

About Small Wind Turbine Wind turbines convert wind energy into electrical or kinetic energy. Small wind turbines are used for the micro-generation of energy mainly to small-scale commercial customers and residential customers. The blades of small wind turbines are usually 2-8 m in diameter. These turbines can generate between 0.01 KW and 100 KW of power. Small wind turbines are used to meet small-scale energy demands from end-users such as residential customers‚ schools‚ small commercial and
