One of the main contributors of the increasing demand for energy is the fast global economic growth. Other conventional fossil fuels such as coal, oil and natural gas which have been a key source of energy since industrial revolution, are not only facing depletion but they have become a source of concern regarding its serious adverse effect on our environment (Abbassi, Premalatha, Abbassi & Abbassi,2013). Hence, the pursuit to develop renewable and clean energy sources, such as solar, wind and hydro power is energy needed. Wind power is considered as one of the cleanest sources of energy, with mild impacts on the environment, on wildlife and on human life, as far as the production of electricity from modern wind turbines is concerned (Leung &Yang,2011).
2. A brief history on wind energy
The earliest form of the use of wind energy by humans is the use of natural breeze to dry and cool the body with or without the help of sunlight. Wind energy has a history of more than 3000 years old, and people began to use it to generate electrical power about 120 years ago. When people learned how to make boats, wind energy was used to help sail the boats. Indeed for several thousand years wind was used as a source of transportation energy in this manner, the speed and the direction of the boats and ships were controlled by the number and the orientation of their sails (Leung &Yang, 2011).
In Egypt, people began to use windmills to pump water. Chinese farmers started to use wind wheels
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.
Wind turbines have evolved over the years to develop into what they are today. People have been using technology for years. For example, it was used for transportation sailboats as early
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.
One of the fastest growing energy sources in the world, wind power is a globally advantageous renewable resource.
Energy is considered as one of the most important factor to run the world. Most of the energy or large part of it are generated by the fossil fuel, which are being used from a long time which are causing a major problem in environmental and the damage done is not reversible. As the fossil fuel are damaging and are also limited in quantity available, so the need of alternate energy was needed. Wind energy is considered as low effects on the environment and growing faster day by day which is considered as quarter in last few decades. The process of capturing is considered as easy as and less damaging than the other energy sources. Wind power is taken
Wind powered machines are developed by the Babylonians. King Hammurabi of Babylon used wind powered scoops to irrigate Mesopotamia. Aside from irrigation and drainage, windmills were also used to ground grain, but maybe later on in history. This is just another advancement making work easier, yet more productive for mankind.
The first known sources of energy were wood and coal. However, if you were to ask everyone to return to a time where the conveniences of travel such as cars did not exist it would be impossible. Even the Amish people don’t rely on wood and coal, relying instead on batteries, propane gas as well as wind plants (Kraybill). Wind power was used as early as 5000 B.C. where it helped speed boats along the Nile River. It was also used to power windmills in China in 200 B.C. New windmills were created to grind grain in Persia as well as the Middle East. Those same windmills were adapted to solely produce food, while the Dutch used wind power to expunge water out of lakes and marshes. It was later in the 19th century that windmills had been re purposed
How did people first use wind power? Well the ancient egyptians were thought to have used wind power to push their boats trough dangerous cateraks. That was as early as 5000 B.C! Around 200 B.C The Chinese and Persians learned how to use Wind power. The Chinese were pumping water using a simple three bladed windmill, while the persians were using a vertical axis windmill made of woven reeds to grind grain. I can’t believe the Dutch innovated the windmill to drain lakes and marshes in and around the Rhine River Delta! The american colonists also used a windmill to pump water, cut wood in the sawmills and to pump water. In World War II, 1940, there was a wind turbine that sat on hill in Vermont named Grandpa's Knob, it was a
Windmills date as far back as 200 BC. The first windmill was known as “Hero of Alexandria”, located in what is now known as Iran, but was not too successful. These windmills were tweaked over many years to have a well functioning purpose. The main purposes of the windmills in ancient times were water pumping and grain grinding. Windmills have been used for thousands of years, allowing for a revolutionary way of completing certain tasks.
People used windmills back as early as 5000 B.C. They were pumping water and helping grind grain. In the 11th century, windmills became assets to farmers by helping food production. The idea spread, and along with helping food production, it also helped pump water, which, after much modification, became able to generate electricity. Daniel Halladay was the first person to design a wind turbine in the US. He did it in Connecticut, and the windmill became successful and helpful on farms. Wind turbines have gotten bigger over time, allowing them to generate more electricity due to the fact that they harness more energy with bigger rotors. Governments started to advance technologies, and once they teamed up with NASA, it led them to create a wind
Jason M. Everett claims that “The kinetic energy in the wind can be used to turn a propeller-like wind turbine connected to an electric generator. The generator converts the kinetic energy into electrical energy, which can then be used to power a wide range of things.” Because of this, “Wind energy comes from the sun. As solar radiation heats the earth’s surface, hot air rises and cool air fills the voids. This air movement is defined as wind energy. Wind that is harnessed via mechanical means is also referred to as wind energy.” Jason M. Everett states
One of the positives of wind power is that there is huge potential. If all of the energy of surface wind energy was extracted it would be well more than the total amount of power the world uses (1). Another positive is the cost of operations of the wind turbines. The cost of operating wind turbines are very low to maintain. After an original cost the turbine, annual costs of maintaining turbines are only 3% of the initial cost of the turbine (2). The main reason wind turbines are being used is because it is clean energy. The energy from wind turbines is not destructive to the environment
“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
In the society we live in today, many people have the misconception that there is a never-ending supply of energy available for our wasteful use. However, people must realize that the fossil fuels that we have come to depend on for our energy are quickly being depleted. There are several renewable energy resources, most of which come from the sun, that are available for our use. One of these abundant energy resources is the wind. By taking advantage of the wind, and harnessing its power to supply useful energy, people can ensure that they will have energy for as long as the sun continues to heat the earth.
Since 400-500A.D, people used windmill energy in farms for grain grinding and water pumping. In 1888, the first wind turbine that generated electricity was discovered by Charles F.Brush in Ohio, USA. However, there are limitations on speed.
