business idea – Wind energy

For several years, environmental protection has attracted much interest and, consequently, several technologies have developed. This is the case of wind energy. Previously, we used this source of energy for pumping water or grinding wheat to make flour. Today, this energy source is still used to pump water but it is mainly used to produce electricity, without any adverse effect on the environment. The increase in operating costs for nuclear and fossil fuels have also allowed Wind Power to become much more competitive.

“The turbine Wind vertical developed by Canadian has more advantages. “

Wind energy is used for a very long time. It is obtained when the wind pushes against a propeller slightly bent. This forces all to turn and pump well water or turns a generator to produce electricity. There are two types of wind turbines, vertical axis turbines and those horizontal axis. Most wind turbines are horizontal. They have some disadvantages, among others, the generator is located at the top of the tower, which makes difficult the maintenance and repair. The vertical wind turbine, developed by Canadians, has several advantages. First access to the generator and the main mechanical components are located at the foot of the tower. Moreover, no system to direct the turbine into the wind direction is required. This turbine is still developing, but it is anticipated that when fully functional, it will mean a significant commercial

Wind energy is extracted from the wind through a turbine and then be converted into electricity by a generator. The generator current is sinusoidal and when plugged into the electricity grid, its frequency must be the same as the power grid; is 60 Hertz. As the speed of the impeller determines the current frequency of the generator, it is necessary that the turbine rotates at a constant speed. For this reason, much of the energy is not extracted from the wind. Nowadays, it is very important that a device operates at a very high yield. The same principle applies to wind turbines. Furthermore, researchers have discovered that it is possible to extract more energy from the wind by correcting the current to obtain a sinusoidal current. Then, with the help of a converter, the current is transformed back into a sine wave but with a fixed frequency of 60 Hertz. This means that the turbine can turn almost any speed and thus extract more energy. Although the converter is often very complex and is expensive, the energy gain is worth the effort.

The question now, how much can cost a wind turbine? It costs just over $ 1.00 for each watt of power. A wind turbine system with a capacity of 10 kilowatts (kW) costs about 10 000.00 $. In order for a wind turbine is economically viable, it must be installed in a region where the winds blow so intense. It is often advisable to conduct a study into the potential region to determine the strength and height of the wind for a whole year. The regions bordering the ocean as well as open spaces are usually ideal for extracting wind energy. In northern Canada, there are systems in place to generate electricity. Since the grid is not present in all communities, a diesel generator with a wind turbine is often used. This reduces operating costs of the diesel system.

Wind power also has disadvantages, including the unpredictability of the wind. For this reason, the utilities have great difficulty accepting this energy source. In most cases, a wind turbine is installed with a diesel generator or simply plugged into the mains. The wind turbine can not operate alone. Similarly, in some communities, the appearance of the turbine is very important. The turbines are often monumental in scale and thus it is difficult to accept such a unit within the population. The wind power is the only source of electricity whose deleterious ecological effects are almost nonexistent. This energy source does not emit harmful to the environment and moreover, it is as competitive as other sources of electricity. Nowadays, people are sensitized to the reduction of harmful gases on the environment. Therefore, wind energy represents a source of energy for the future of Canadians.

Wind Energy in Colombia $14.99 The wind regime in Colombia has been rated among the best in South America. However, under the current circumstances, and on its own, the interconnected system would not likely promote wind power. This report is targeted to analysts, planners, operators, generators and decision makers in Colombia and other countries in the region and provides a set of policy options to promote the use of wind power. The potential instruments assessed in this study include financial instruments, government fiscal mechanisms, and adjustments to the regulatory system. The single most effective policy instrument to promote wind power in Colombia consists on valuing the firm energy offered by wind, its potential complementarity to the hydrological regime and enabling wind power an access to reliability payments.

Urban Wind Energy $97.5 Energy security, rising energy prices (oil, gas, electricity), 'peak oil', environmental pollution, nuclear energy, climate change and sustainable living are hot topics across the globe. Meanwhile, abundant and perpetual wind resources offer opportunities, via recent technological developments, to provide part of the solution to address these key issues.The rapid growth of large-scale wind farm installations has now led to the generation of clean electricity for tens of millions of homes around the world. However, despite the potential to reduce the losses and costs associated with transmission and to use local wind acceleration techniques to improve energy yields, the potential for urban wind energy has yet to be realised. Although there is increasing public interest, the uptake of urban wind energy in suitable areas has been slow. This is in part due to a lack of understanding of key issues such as: available wind resources; technology integration; planning processes (include assessment of environmental impacts and public safety due to close proximity to people and property); energy consumption in buildings versus energy production from turbines; economics (including grants, subsidies, maintenance); and the effect of complex urban windscapes on performance.Urban Wind Energy attempts to illuminate these areas, addressing common concerns highlighting pitfalls, offering real world examples and providing a framework to assess viability in energy, environmental and economic terms. It is a comprehensive guide to urban wind energy for architects, engineers, planners, developers, investors, policy-makers, manufacturers and students as well as community organisations and home-owners interested in generating their own clean electricity.

Wind Energy Equipment in India $195 How to Strategically Evaluate India. Perhaps the most efficient way of evaluating India is to consider key dimensions which themselves are composites of multiple factors. Composite portfolio approaches have long been used by strategic planners. The biggest challenge in this approach is to choose the appropriate factors that are the most relevant to international planning. The two measures of greatest relevance to wind energy equipment are “latent demand” and “market accessibility”. The figure below summarizes the key dimensions and recommendations of such an approach. Using these two composites, one can prioritize all countries of the world. Countries of high latent demand and high relative accessibility (e.g. easier entry for one firm compared to other firms) are given highest priority. The figure below shows two different scenarios. Accessibility is defined as a firm’s ease of entering or supplying from or to a market (the “supply side”), and latent demand is an indicator of the potential in serving from or to the market (the “demand side”). Framework for Prioritizing Countries. Demand/Market Potential Driven Firm. Relative Accessibility. Accessibility/Supply Averse Firm. In the top figure, the firm is driven by market potential, whereas the bottom figure represents a firm that is driven by costs or by an aversion to difficult markets. This report treats the reader as coming from a “generic firm” approaching the global market – neither a market-driven nor a cost-driven company. Planners must therefore augment this report with their own company-specific factors that might change the priorities (e.g. a Canadian firm may have higher accessibility in Canada than a German firm). Latent Demand and Accessibility in India. This report provides a detailed overview of factors driving latent demand and accessibility for wind energy equipment in India. Latent demand is largely driven by economic fundamentals specific to wind energy equipment. This topic is discussed in Chapter 2 using work carried out in India on behalf of American firms and authored by the United States government (typically commercial attachés or similar persons in local offices of the U.S. Department of State). I have included a number of edits to clarify the information provided. Latent demand only represents half of the picture. Chapter 2 also deals with micro-accessibility for wind energy equipment in India. I use the term “micro” since the discussion is focused specifically on wind energy equipment. Chapter 3 is also a stand-alone report that I have authored. It covers proxy pro-forma financial indicators of firms operating in India. I use the word “proxy” because the provided figures only cover a “what if” scenario, based on actual operating results for firms in India. The numbers are only indicative of an average firm whose primary activity is in India. It covers a vertical analysi

South Africa: Wind Energy Barriers $50.1 Hauptbeschreibung The rapid adoption of wind energy in the renewable energy mix can be seen in many industrialized nations in the past decade, in particular the need to agreed greenhouse gas reduction and stable energy supply are seen as a sound vision for a sustainable energy policy’. In an emerging market such as South Africa there are abundant renewable resources including wind energy, however there is low adoption observed to date. This study investigates barriers to entry in the South African wind energy sector and what the priorities are to remove such barriers for successful deployment of wind technology. Therefore, it was required to examine successful deployment of wind energy in the European Union and how such barriers were removed; this was set in the current status of the renewable energy sector and existing barriers in South Africa. It was necessary to gain insight of the inter-related issues on opening a traditional fossil fuel based energy market to a transitional implementation of renewable energy provisioning, considering the current utility monopoly based energy landscape in South Africa.   Biographische Informationen The author works in the area of Global consulting in Environment, Infrastructure Utilising Renewable Energies multiple sectors.
