Global Annual Installed Wind Power

According to research done by Discovery News, in January 25, 2013, the top 10 countries, by order of most demand and use of wind energy, are: China, United States, Germany, Spain, India, Italy, France, Canada, Brazil, and Denmark. All of these countries are investing money in wind turbine projects because, in the long run, it is going to benefit them from both the economic and ecofriendly point of view (Discovery News). In addition to these top ten countries in the world, there are more countries that have, or are, investing in these types of projects, since this is the future and correct path for the use Renewable Energy as a replacement for fossil fuels. Fossil fuels are harming the environment to the point where in a short amount of time it is going to be almost impossible to live on Earth because of the catastrophic changes the pollution will cause.

One of the fastest growing energy sources in the world, wind power is a globally advantageous renewable resource.

Theres no marketplace for the need and supply of wind energys, it might be used by anyone and is among the lowest cost renewable technology presently available, depending upon the wind source and the specific projects funding. Industrial and Domestic Installation: Wind turbines could be constructed on farms or ranches where bulk of the best wind sites are located. Wind turbines uses just a small percent of the land which causes no difficulty at work for their farmers and rancher, providing landowners with extra income paid by the proprietors of the wind power plants. Many landowners choose to install smaller, less strong wind turbines to have the ability to offer part of a national electricity supply.

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.

The topic of this literature review is wind power and hydropower. The purpose is discovering how wind power and hydropower influences the world and our lives.“Environmental science is the study of the interaction of the living and nonliving components of the environment with special emphasis on the impact of humans on these components. (Hartwick, What is Environmental Science?)

However, one crucial part of establishing a wind power system is high technology, which is now the main defect in the developing world. Even in some developed countries such as Demark, lack of expert engineers in the wind industry is noticeable. It is convincingly argues that there is quite an engineering challenge especially for the less-developed nations to design an efficient wind turbine harnessing energy and turning it into electricity. In addition, it seems rather a challenge to offer opportunities for technology transfer, training and practical experience for the industry and potential wind energy supporting industries and organisations for the current developing world.

The report provides an analysis of the nonmarket issues of the wind power market and provides information relating to wind power projects in Canada. The report aims to help communities balance local concerns with wider environmental needs, thereby allowing the benefits of renewable energy to be realized through careful design and consultation. Additionally, it also provides a profile of a major wind power company in Canada.

Wind force is still the most encouraging renewable energy in the year of 2013. The wind turbine system (WTS) began 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.

that fossil fuel supply continues to deplete and sooner or later, the United States will need to resort to a new source of energy. This report hopes to explore the advantages and

Since 1980’s wind turbines have noted a remarked progress making the whole sector and technology mature in order to enable the rapid growth on the market. This is justified by Fig.3 where it is observed that from 1996, the growth is steadily increased till 2012 and is still growing. From then till now, the cost

In the graph, there is the capital cost average, the fixed operations and maintenance average, the variable operations and maintenance average and the fuel cost average. The fixed operations and maintenance average is how much the power source needs to be checked up in its lifetime. The variable operations and maintenance average is when something unexpected happens and they have to go and fix it or check it. The wind energy is the one that costs the least money, and it falls well below average costs for alternative energy sources. The only energy source that comes close to the cheap cost of wind is the Gas Combined Cycle, however, it is still a little bit more expensive. You can see that basically wind energy’s cost is all in the building

Worldwide there is over two hundred thousand wind turbines installed which includes both on shore and offshore wind turbines. Europe is the global leader in wind production followed by china, Canada, Australia and US.

Wind turbine is a device that converts kinetic energy stored in wind to electrical energy using electrical generator. Before invention of electricity Windmill was used to convert energy of wind to rotational mechanical energy. In history we have seen many kind of drag and/or lift type of wind turbines. Currently mostly used wind turbines are three bladed Horizontal axis Wind turbine and Darrieus(or Egg-beater) type wind turbine. Majority of the modern wind turbine have can generate electrical power of 1.5 to 5MW [2]. We can define capacity factor as ratio of total wind energy extracted within a year to the total theoretical maximum power of a given wind turbine. Capacity factor depends on many factors but one on them is very low wind speed which is not enough to run a wind turbine. Wind speed increases at higher altitudes from the earth surface. Thus more energy can be extracted from the wind at high altitudes and in addition to that we have higher capacity factor because of more continuous winds. At 100m height estimated global wind power is about 230 TW [3]. We can get high amount of wind energy (80 GW as in [4].) at

In the 21st Century, fossil fuels are becoming increasingly important, with the demand for these resources increasing, despite the knowledge that they are finite. Globally, the annual consumption of fossil fuels is eleven billion tonnes, with crude oil reserves waning at a rate of four billion tonnes per year. If these figures experience little change in coming years, oil reserves are estimated to completely deplete by 2052 (Ecotricity.co.uk, 2014). Other options are available to replace non-renewable energy sources, one of these options being wind turbines, as they are the obvious option to be used as energy sources as wind is without charge. Wind power requires harnessing energy from the wind, and using it to generate electricity. According to Blue-energyco.com (2014), wind power generation is the fastest growing renewable energy source universally, as evidenced by the growth rate which stands at 25% in over a decade with the total capacity currently exceeding 60 000 MW (Fox, B. (2007) Wind power integration, page 1).
