What Are The Advantages And Disadvantages Of Wind Turbines?

For many, the mention of wind energy conjures images of giant white turbines, their blades slowly rotating, stretching off into the distance with no end in sight. This is how it has been portrayed in pictures, but this is not how wind energy truly looks. Photographs in books and magazines imply that wind energy would require these never ending fields. On the contrary, smaller fields where a limited amount of turbines create all the power needed and more for a city that is nearby, or smaller individual turbines creating enough energy for a home or neighborhood without being obtrusive, is how wind energy truly looks. Wind energy harnesses the power of the wind and converts it to other forms of energy, one of the main known forms being electricity.

Wind is a form of solar energy so when it is used it creates electricity. Electricity is a physical phenomenon associated with fixed or moving electrons and protons. The wind power development was a step forward for the use of electricity on how to generate more electricity using the wind. The accomplishments for electricity is that Senegal used 10MW for a wind farm and they gave a positive report and is now using it since the second half of 2005. (Dodge) Another thing is during the Second World War; small wind generators were used on German U-boats to recharge submarine batteries as a fuel-conserving measure. The good thing about wind power is can produce electricity at night as well as during the day and that it is plentiful, renewable, and it reduces the greenhouse gas emissions. (ERIC) The Wind Power would be cheaper to develop electricity and it is less harm to our daily lives.

The way the wind turbine works is when the wind blows, the blades on the wind mill (or turbine) are spun to run the motor that is attached to the back of the turbine. The motor transfers its energy through wires to a substation where the energy is transferred into electricity that can be useful for residential and commercial areas. The energy is then delivered through wires across the country.

As the global supply of fossil fuels becomes steadily lower, need is growing for new energy sources that are beneficial to the environment and cost-effective. Wind power is one solution to this need. Wind turbines require significant investment, but are cost-efficient in the long term. If construction of turbines is sufficiently increased, the wind may be able to in the future provide a very major portion of global energy.

Unlike its sister energy supply, fossil fuels, wind power is a clean resource. Wind turbines don’t pollute the air like power plants, which rely on the burning of coal or natural gas. They’re free from producing atmospheric emissions that cause acid rain or greenhouse gases.

The wind occurs naturally in nature and it can be harmful or helpful. We use it as another source of clean energy, and like solar energy it will never run out. Windmill farms have been produced to help harness the ability of producing electricity through the use of turbines. The cost is low and no gases are released into the atmosphere to destroy the earth’s protective barrier known as the ozone.

The wind turbines are made and created from a local power plant in Valeria and it helps create kinetic and solar energy. The Wind Power is sustainable because wind turbines are a conversion to kinetic energy and the wind is mechanical power. But the

The first reason is that they are really expensive to build. It takes $1.3 to $2.2 million to build a windmill. Wind turbines under a 100 kilowatts cost $3,000 to 8,000. All the parts of the windmill are located at the top. Also you have to have a lot of people to operate it.

It has to be AT LEAST 8.7mph to turn a wind turbine. Another disadvantage about wind power is shadow flicker it is when the blades of the wind turbine cause a shadow as it turns. It would cause unwanted repetitive shadows over neighboring houses or buildings, it could be mistaken for power outages or even earthquakes. Finally, the sound of wind turbines they are not silent for the people that live near the wind farms would get unwanted noise in their houses content during the day and at night.

Wind turbines can be placed on land or water, and can be placed at different altitudes, making the search for wind farm locations easy. Wind farms can be placed on traditional farms as well.

“A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy”. (1) The inventor of the first electric wind turbine was Clevelander Charles Brush, who ran his entire Euclid Avenue mansion off of one for 20 years, which later made the cover of Scientific American in 1888. (2) Although the use of alternate energy didn't rise a great deal afterward, this event did open the eyes for many environmentalists. Wind power is only one of our several “energy source[s] whose ‘fuel’ is free and will never be exhausted” (3) with the pros and cons not completely weighed out as to whether it will be truly beneficial or not. The two main issues regarding wind turbines are the environmental effects that they have and the

On the environmental aspect, wind energy does not contribute to pollution as almost no waste materials that contribute to pollution are produced by the usage of wind power (Wright, 2005). For example, in the States, wind plants compensate the emission of than 2.5 billion pounds of carbon dioxide and 15 million pounds of other

• The average household generates approximately 1.2 to 1.6 kw/h. Wind turbines can generate from around 600 kw/h, to 4.4 Mw/h. That is equivalent to lighting approximately 10,000 to 100,000 light bulbs at once.

Wind energy is essentially the conversion of the kinetic energy from air molecules in motion to mechanical energy which is generally then converted into electrical energy. People have used wind power since 700 AD in

Wind energy is the type of energy which is converted from wind into electricity. It is a renewable source of energy which can provide certain amount of electricity according to the variability of the wind, “yet, wind does not blow 24/7/365 in most location” (Kevin & Brian, 2012:41). The wind power turbine is made on the outside of a tower, blade, rotor, pitch and the nacelle. Although wind energy does not causes pollution in the environment, the flying creatures have few chances of surviving when taking a direct hit through a rotating wind power turbine. The rotating motion of a turbine causes noise therefore building a wind energy power in an urban area should be avoided.
