Essay on Renewable Energy: Wind 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.

We live in a world that is frantically searching for alternative energy sources to reduce our dependence on fossil fuels and offset our negative environmental impacts. In recent years, wind production has presented a very appealing argument in favor of renewable energy. Wind energy is not associated with the typical negative environmental impacts that stem from our traditional energy sources such as air pollution, water pollution, mercury emissions, and climate change (NWCC 1). Wind power’s promise as a clean, free energy source is not the only reason why it has gained modern popularity. Many factors have fueled the wind energy movement. Due to ambitious big wind companies, support from the government and public consent, wind farms have become

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.

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.

“Worldwide, hydropower facilities possess a significant amount of installed electric generating capacity. IEA statistics indicate that at the end of 2001 there was in excess of 450,000 MW of installed capacity within IEA member countries, with about half in Europe and half in North America. In addition to conventional hydropower, there is more than 80,000 MW of installed pumped-hydro capacity in IEA countries. In contrast, utility-scale wind power is relatively new in the electric market, but increasing rapidly” (Integration of Wind and Hydropower Systems)

In 1986, the National Renewable Energy Laboratories developed a wind resource assessment for the U.S. Department of Energy. The assessment consisted of surface wind data and upper-air data. The results of this project help today’s developers determine the best location for a wind farm, as shown in

One of the parts of the main application of the engineering mathematics to produce energy by wind is a mathematical model for the size of the windmill blades which will touch the wind and transits the power to the

Wind power is still the most promising renewable energy in the year of 2013. The wind turbine system (WTS) started with a few tens of kilowatt power in the 1980s. Now, multi megawatt wind turbines are widely installed even up to 6–8 MW. There is a widespread use of wind turbines in the distribution networks and more and more wind power stations, acting as power plants, are connected directly to the transmission networks. As the grid penetration and power level of the wind turbines increase steadily, the wind power starts to have significant impacts to the power grid system. Therefore, more advanced generators, power electronic systems, and control solutions have to be introduced to improve the characteristics of the wind power plant and make it more suitable to be integrated into the power grid. Meanwhile, there are also some emerging technology challenges, which need to be further clarified and investigated. The global electrical energy consumption is still rising and there is a steady demand to increase the power capacity. The production, distribution and the use of the energy should be as technological efficient as possible and incentives to save energy at the end-user should be set up. The deregulation of energy has lowered the investment in larger power plants, which means the need for new electrical power sources may be very high in the near future. Two major technologies will play important roles to solve the future problems.

In traditional networking architecture, control plane and data plane are coupled in the network infrastructure. This traditional architecture has many inherent issues:

Wind is an intermittent energy source; as the wind is not constant, wind turbines do not produce the same amount of electricity all the time. This causes difficulties as the penetration of wind power increases, and wind generation become relied upon by the network operator. This report looks at the impact of wind power on the capacity of a power system to meet demand.

The development of the wind power generation is rapidly maturing, with recognized reliability and affordability. Besides the low prices, the cost-stability of wind energy against the wildly fluctuating prices of fossil fuels is making it a very smart option for the consumers, independent power producers and corporations. This is clearly reflected in the growth of the global annual installed wind power as shown in Figur. After a slowdown in 2013, there is a 44 % increase in the wind power installation, which shows a solid sign of the recovery in comparison to the past few years. Total cumulative installed wind power all around the world at the end of 2014 is 369 GW []. The annual installed capacity of wind power by region

Wind power is a clean and renewable energy that, while at times unreliable, has very low upkeep cost and is growing at a rapid rate. While there is currently enough wind power to provide many times our current energy need, it is unfeasible in reality. Wind power utilizes the kinetic energy of air and uses it to power a generator to produce electricity. Even though dependence on wind power is impossible, it still can provide a strong, clean, quantity of power to supplement current energy production.

Network Topology is how computers, printers, and other devices are connected over a network (“Guide to Network Topology”, 2015”). The word topology means shape and the term network topology refers to the shape of a network (“Guide to Network Topology”, 2015). Network topologies refer not only to the physical layout of the devices connected but how the devices communicate to each other (“Tomsho, Tiffel & Johnson, 2004, pg 48”). There are several different topologies and the choice of a topology is determined by how the network works. The network cabling system carries all the data from one point to another and the design is determined by how the network should function, the reliability and how accessible the network should

Setting up windmills and other wind harnessing hardware is costly, the innovation behind it is additionally costly and concentrated expanding the underlying expense of setting out the plant (Krohn, Morthorst, and Awerbuch, 2009). Be that as it may, the examination demonstrates that the approach is unsurprising and sure in spite of the cost not at all like different sources particularly the non-sustainable
