Essay on Wind Power

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.

• According to the World Energy Council, the global installed capacity of offshore wind capacity reached around 12,107 MW by the end of 2015, with 2,739 turbines across 73 offshore wind farms in 15 countries. It further says that in 2016, more than 92% (10,936 MW) of all offshore wind installations are in European waters but that governments outside of Europe had set ambitious targets for offshore wind, and that development had started to take off in China, Japan, South Korea, Taiwan and the US.

Wind turbines have altered the way that we get our energy. Wind turbines are used to harness wind power and turn into electricity. They are comprised of usually 2 or 3 blades that are connected to a shaft that was attached to a generator which then turns into electricity. Although we now generally use it to produce electricity, wind energy was originally used in the form of windmills to do chores and housework. Because of the rapid increase in the use of wind turbines, it has added jobs and changed the way we get energy.

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.

Imagine getting free electricity, or electrical company’s paying you instead of you paying them, today’s windmills just might make this possible. Windmills dating back as far as the 1400’s have been used to turn wind into useable energy for grinding and pumping. Today’s windmills turn turbines to make electricity. They are popping up all over the United States, but the United States is way behind other countries in the development of wind energy. Countries like Denmark, Germany and the United Kingdom are investing billions of dollars into wind energy, including off shore wind farms. Germany is holding the top spot in the production of wind-generated electricity. Denmark, being one of the smaller countries in Europe, produces twenty percent

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.

A two-bladed turbine is the next most efficient because each blade sweeps 180 degrees before reaching the wake of the other blade, but you get something called yaw chatter when the turbine rotates to face the wind. The yaw chatter cause noise, vibration, and stress on the tower.

B. Turbine Blades and internal parts such as motors are the main part of the Windmill. Materials used in the HAWT lead to effect more cost. Unlike the materials of VAWT, the materials of HAWT are made of high composites metals and steel blades, power required to store the energy in the end in the generator is more, and it must be installed near offshore or remote areas (K. A. Brown*). However the turbine blades made up of composite materials such

Did you know that windmills are used to power homes across America? I think wind energy should be used in America, because "Wind power is an increasing valuable source of energy," says Shirley Anne Ramaley.  In other words wind is a reusable source of energy that we can use forever.  Wind energy is a great source of energy, but it can cause a few problems.  Let me tell you a little bit more about wind energy.

The issue here is should Wind Technology compete in the HVPS market?
Based on the estimated “attainable” market potential of ______________________, a one-half (0.5 percent) market share would correspond to ___________________$ sale? After subtracting production costs, what is the approximate profit available? _____________________ $

“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

Europe has been the vanguard of innovation and novelty in offshore wind. In Denmark, the very first project of offshore wind was established in 1991. Despite its present non-existence of noteworthy offshore capacity, the U.S. also has plans for the improvement of offshore wind power of the Atlantic coast.

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.

The type of turbine purchased depends on the wind speeds, the electricity the grid can absorb and the cost of the turbine. According to the United States International Trade Commission in 2008 there were 13 turbine manufacturers with two United States manufacturers generating 50% of the market. The chart below shows the dimensions of a turbine for three of the top manufactures.

The main cost of wind energy is in the initial investment in the construction of a wind turbine; the upkeep cost is generally marginal and lower than one cent per kWhr. In general, wind power works by having air molecules move across the turbine blades transferring kinetic energy from the molecules to the turbine, causing it to turn. As it turns, the mechanical energy can be used to perform tasks such as grinding grain. More commonly, the turbine turns and utilizes a power generator to convert the mechanical energy to electrical energy.
