Essay on The Importance of Wind Turbines for Renewable Energy

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.

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.

Everyday, this mysterious force known as the wind blows constantly around planet Earth. No one knows why the wind blows, but that did not stop individuals from harnessing its power. In past times, Persians and Daniel Halladay were able to invent their own versions of the windmill. Each design served a slightly different purpose than the other.

Wind is air in motion, and is caused by the uneven heating of the Earth’s surface by the sun (“Wind”). Because of this, wind energy has less impact on the environment then other energy sources. Therefore, wind can produce electricity through a turbine or windmill. A wind turbine is a device that converts kinetic energy from the wind into electrical power. (“Wind Turbine”) In order for a wind turbine to work there are many properties that must be present such as: wind, wind speed, location with the right wind, as well as other characteristics that come to play such as short and long term fluctuations and the distribution of wind direction.

When the wind is blowing on wind turbines it produces electric power, Fans are old techniques used in the mills and then the water pump, but now it has developed the technology and has become used for electric power production.

The lab tested various properties associated with wind turbines while measuring the effect on the power. It was shown that wind turbines can supply a significant amount of energy and power. This wind energy has an important application with wind turbines across windy areas of the United States. These turbines can provide power as a replacement for nonrenewable resources. Although wind energy might not be the most vital form of energy currently, it could become a very important alternate energy source in the near future. Wind turbines can be placed all across the United States wherever there is a strong amount of wind. When talking about implementing wind energy there are a lot of things to think about.

Wind energy is a clean, alternative source of energy that does not produce greenhouse gas emissions and can be produced domestically. While wind energy accounts for a small overall portion of the energy produced in the United States, the potential for wind energy is significant. Nevertheless, there are some obstacles that delay the widespread use of this technology, including intermittency of wind, cost, and public policies that deter their implementation.

This report presents the whole process and all the results of the wind turbine lab, data calculations and results discussion.Wind turbine lab including the use of two software,which are very vital in the wind energy industry, Bladed and Matlab. Almost all the data in this report are calculated by Bladed , and then imported to Matlab for more accurate digital image. There will be a lot of data and diagram related to the wind turbine,curves figure and some data figure (tip speed ratio,electrical power, rotor speed generator speed,etc).All of them are key concepts for the course.Why pitch regulation? How does it work?Why variable-speed? How does it work? And which turbine is it? Getting close to the answers to the questions through curve producing , data calculating and results discussing . Comprehending more about those key concepts and understanding more about the principle of the Wind Turbine is the point of the whole process.

A wind turbine is the opposite of a fan. Instead of using electricity to make wind, wind turbines use wind to make electricity. Wind turbines convert the potential energy in the wind into kinetic energy that results in mechanical power- The turning of the blades and drive shaft. The mechanical energy can then be used for traditional tasks such as grinding grain or pumping water. Modern wind turbines use generators to convert this mechanical power into electricity that can power homes, businesses, schools and other buildings. Wind turbines are often grouped together into a single wind power plant also known as a wind farm, and generate bulk electrical power. Electricity from these turbines is fed into a utility grid and distributed to customers, just as with conventional power plants. Wind turbines come in a variety of sizes and power ratings. Utility-scale turbines

These turbines are connected to the compressor and also the fan. So basically when turbines rotate, the compressor and the fan also rotate. What happens is that the airflow coming from the combustion chamber makes the turbines rotate and as the turbines rotate, they also make the fan and the compressor spin. Finally the gases exit through the nozzle.

Offshore wind power has become a need of the hour in renewable energy production due to the rising prices of oil and continually increasing demand for a separate energy sector. Offshore wind has the prospective to deliver at least four times the current U.S. demand of energy, as per mentioned by the Global Wind Energy Council. However, there are many challenges and advantages that are significant for us to comprehend.

We are facing an energy crisis on Earth. Burning fossil fuels are harming the atmosphere; this global warming and affects produces chemicals that hurt our body. People are starting to think about using alternative energy. Wind power would be our first choice, because it’s clean, inexhaustible and renewable. Today, wind power is mainly used in Europe. We believed wind power would be the main source of alternative energy for world use.

Wind power is regarded as a renewable energy source since wind is a clean, free, and is in abundant supply. The wind current can be used to generate electricity when it is harvested by wind turbines. Wind turbines are mounted on a tower to capture the greatest amount of energy. At 100 feet or more above the ground, the tower allows the turbine to take advantage of faster wind speeds found at higher altitudes. When the wind blows, the turbine’s blades spin clockwise and captures energy. As the wind turbines capture the wind’s power, it converts the kinetic energy of wind into mechanical or electrical energy, which can be used for power.

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.

Wind energy conversion is a fascinating field to study, if only because its past has been so checkered and its exact future is so uncertain. Unlike the aerospace industry, the computer industry, and almost any other successful industry you can name, wind energy -- the
