Free Example of Wind Energy Technology Essay

When the wind is drives, the wind propels the blades of a wind turbine, which turns the rotor. The rotor turns the generator on and this whole system produces electricity. The wind power plant consists of more than 100 turbines.

The history of wind mill exists through century. In early 1980s the commercial development of wind electric generation was given by United States. They contain the geared transmission and induction generators which has high rpm and rotor blade. Today technology is advancing most of the new materials are used to develop the new technology of the wind mill.

Cost of wind energy

The cost of wind energy is determined by: 

                     1. The initial cost of the wind turbine installation
                     2. The interest rate on the money invested
                     3.  The amount of energy produced                 

Cost is somewhat higher than the costs associated with an electrical facility, but wind energy costs are decreasing every year, whereas most conventional generation costs continue to increase. Electricity that is generated by the wind is clearly cost effective. When compared to the money that is charged by electrical companies, wind energy costs are nearly competitive. And that is without accounting for the environmental and health benefits of using a non-polluting source of energy. 

They include four main points:

  1. Energy produced.
  2. Total installed cost/ price.
  3. Operations and maintenance price.
  4. Financing cost and other incentives. 

Energy plays a significant role in the generation of the cost of wind energy. The cost of bulk of electricity can be calculated by the installation cost divided by the total amount of electricity produced. The turbine location is the major determinant while its technology plays the role of major factor in energy generation.

The machine quantity and value of electricity generated depends upon the qualities of speed, duration and variability at the location.  The small difference in the speed of the wind can cause a major difference in the power. We know that the wind increase proportionally with the cube of the wind speed.

The variability of the wind also plays an important role in determining the cost. The total cost installed includes the cost of the turbines, foundation, electrical grid interconnection system and construction cost.  Financing cost and the incentive also plays a big part in determining the cost.

The greatest land based wind resource in US is the Great Plains from North Dakota to Northern Texas. These resources are however kept away from the population area and the power delivered is also from the generator to loads.

Spain is the world fourth biggest producer of wind power. It has the capacity of 16740 megawatts. It is the second Spanish power for the city the wind mill. The largest producer of wind power in Spain is Iberdrola, second is Acciona. On a windy day the power is more generated in Spain than the nuclear.

The Spanish government has sanctioned a green energy approach to guarantee an increase the wind capacity for generating the electricity. The wind power industry is growing day by day. The manufacturer includes blade, towers, turbines, and generator. Suppliers include hydraulic and electrical equipments.

Largely concerned with advancing energy efficiency use in Spain, the Institute for Energy Saving and Diversification (IDEA) also seeks to expand renewable energy sources and energies. Concentrated research is occurring concerning wind measurement in the Albacete region at Higueruela.

The national Spanish wind energy industry has begun to export its wind generators by forming contracts. It has formed its contract with highly developed states like Portugal, Turkey, Tunisia, Brazil and Argentina. Three factors will control the further progress of wind power development: the capability of the wind farms network to hold all the electricity harnessed by wind power, predominantly in off-peak times, the cost of energy, and the environmental effect. There are some issues also which keeps on following:

  1. Formulating its development to be congruent with required supply agreements by the national electricity supply operator.
  2. Guaranteeing that the installation of wind farms occurs with recognition of the environment.
  3. Trimming down the investment costs to acquire sufficient returns with declining energy prices in the upcoming years.
  4. Synchronizing wind power development of the 17 autonomous regions.

Research concerning the production of hydrogen from the use of water by a wind farm is occurring at a newly installed laboratory in the Universidad Pública de Navarra under an agreement between Energía Hidroeléctrica de Navarra, Stuart Energy Systems of Canada, and Stat Kraft of Norway.

A partial list of wind farms in Japan include:

1. Hibikinada wind farm

2.  Aoyama Plateau Wind Farm.

Indian Wind Energy Association has estimated that with the current level of technology, the ‘on-shore’ potential for utilization of wind energy for electricity generation is of the order of 65,000 MW. There are about a dozen wind pumps of various designs providing water for agriculture, afforestation, and domestic purposes, all scattered over the country. The wind farms are predominantly present in the states of Tamil Nadu, Maharashtra, Karnataka and Gujarat. Other states like Andhra Pradesh, Rajasthan, Kerala and Madhya Pradesh have a very good potential.

Important limiting factor of wind power is variable power generated by wind farms. Offshore installation monopile wind turbines are generally more expensive than onshore installations but this depends on the attributes of the site. Offshore saltwater environments also raise maintenance costs by corroding the towers.

Offshore wind turbines will probably continue to be the largest turbines in operation.  Wind speeds in these zones share the characteristics of both onshore and offshore wind, depending on the prevailing wind direction. This is done to exploit the so-called topographic acceleration as the wind accelerates over a ridge. 

Utility-scale wind farms must have access to transmission lines to transport energy. The company or person that develops the wind farm can then sell the power on the grid through the transmission lines. Wind Farm has enhanced the area, saying that the turbines are impressive looking and bring a calming effect to the town.

Today’s windmills are extremely high tech, made from special composite, lightweight materials and include high-tech turbines. A standard windmill such as the ones that were created centuries ago can be constructed with simple tools, materials and how.

The types of materials and construction will be vastly different and the overall cost will be significantly higher too. When constructing a basic windmill, keep in mind that your goal is to maximize the conversion of wind energy into mechanical energy. The windmills which are sometimes are referred to as turbines, catch the wind energy and convert it to mechanical energy or electricity.

The components of windmill include the following things they are:

  1. The base.
  2. Tower.
  3. Wind blades.
  4. Nacelle which is a gear box to facilitate blade movements.

The windmill blades:

The blades are very similar to the blades found on an airplane’s propeller. The windmill uses these blades to capture wind energy. You can purchase wind blades or make them from light weight plastic or wood. The size of the base and tower will determine the size of your wind blades. For a basic windmill that stands 5 feet high, wind blades can usually be from one to three feet in length.

The windmill tower:

A windmill tower for a basic windmill that measures about 5 feet high can be made from a strong piece of 2 X 4, plastic PVC piping or other strong materials.

The windmill base:

The base of your windmill should be strong and relatively heavy compared to the rest of the structure. You can use concrete, a sandbag, etc. For a windmill that is five feet high, a base of about 18 inches square and about 20 pounds in weight should be sufficient.

The windmill nacelle:

The nacelle would normally contain a gearbox. However for a basic windmill, you can use a simple shaft to connect all the windmill blades to the tower which will allow it to spin.

For those interested in building a working windmill to convert the wind’s energy to electricity, you can purchase windmill construction plans on the Internet. These windmills can be tens of feet high and include high-tech blades and nacelles.

Danger to birds and bats has been a concern in many locations. Almost nothing is known about current populations of these species and the impact on bat numbers as a result of mortality at wind power locations. Others are in very strong disagreement with the placement of wind farms.

The energy consumed to manufacture and transport the materials used to build a wind power plant is equal to the new energy produced by the plant within a few months of operation. Wind farms have many turbines and each extracts some of the energy of the wind. An ideal location would have a near constant flow of non-turbulent wind throughout the year with a minimum likelihood of sudden powerful bursts of wind.

For smaller installations where such data collection is too expensive or time consuming, the normal way of prospecting for wind-power sites. Another way is to use a wind-speed survey map or historical data from a nearby meteorological station, although these methods are less reliable.

The conversion of wind energy to various other useful forms, like electricity, is known as wind power. Wind energy is converted into these forms using wind turbines. Wind energy can be converted into electrical energy by the use of an electrical generator.

Even today, wind energy is used in large scale wind farms to provide electricity to rural areas and other far reaching locations. Wind energy is being used extensively in areas like Denmark, Germany, Spain, and India and in some areas of the United States of America. It is one of the largest forms of Green Energy used in the world today. Wind Energy is highly practical in places where the wind speed is 10 mph.

Advantages:

  1. It is a renewable energy.
  2. Energy are that it is widely distributed, cheap, and also reducing toxic gas emissions.
  3. Wind Energy may soon be the cheapest way to produce energy on a large scale.
  4. Wind energy generates no pollution.
  5. The wind power available to humankind is harnessed; there can be ten times of energy we use, readily available.
  6. You do not have to be dependent on any country for the energy fuel.

Disadvantages:

1. Wind power is non-polluting; the turbines may create a lot of noise, which indirectly contributes to noise pollution.

2. Wind can never be predicted.

3. Wind Energy is non-dispatchable.

4. Wind energy can be used in areas of high demand.

Benefits of wind energy:

Wind energy is an ideal renewable energy because:

  1. It is a pollution-free, infinitely sustainable form of energy
    2.  It doesn't require fuel
    3. It doesn't create greenhouse gases
    4.  It doesn't produce toxic or radioactive waste

Wind energy is the kinetic energy that is present in moving air; this kinetic energy in turn derives from the heating of the atmosphere, earth, and oceans by the sun. The amount of energy in the wind depends mainly on wind speed but is also affected slightly by the density of the air, which is determined by the air temperature, barometric pressure, and altitude.

The popularity of using the energy in the wind has always fluctuated with the price of fossil fuels. When fuel prices fell after World War II, interest in wind turbines waned. But when the price of oil skyrocketed in the 1970s, so did worldwide interest in wind turbine generators.

Energy that comes from converting kinetic energy that is present in the wind into more useful forms of energy such as mechanical energy or electricity. Wind energy is a pollution-free, infinitely sustainable form of energy. It doesn't use fuel; it doesn't produce greenhouse gases, and it doesn't produce toxic or radioactive waste. 

Windmills that were used to grind grain are an example of early uses of wind energy. Modern uses of wind energy include generation of electricity and pumping water. Current wind energy machines are called wind turbine generators, wind pumps, or more generally, wind turbines.

Since early recorded history, people have been harnessing the energy of the wind. Wind energy propelled boats along the NileRiver as early as 5000 B.C. By 200 B.C., simple windmills in China were pumping water, while vertical-axis windmills with woven reed sails were grinding grain in Persia and the Middle East.
