  • Wind Energy Technologies: Technology, Market and Costs

    Technology Overview   These large wind turbines turn Midwestern wind into utility electricity. Wind turbines convert the power in the wind into electricity. By extracting the kinetic energy in the wind, wind turbines generate mechanical power. In the past, mechanical wind machines were widely used for specific tasks, such as pumping water or grinding grain. Today, wind ...

  • Wind Generators as Role Models

    Advanced speed control methods are available for the regulation of wind generators. Working together with SET Sustainable Energy Technologies GmbH, Sulzer made use of one of these new concepts on pumps for the first time and implemented it with great success on a feedwater pump in a refinery. Unregulated pumps consume unnecessary drive energy when demand fluctuates. By controlling ...

  • Wind power growth in the US

    Last year was a banner year for renewable energy in the United States, especially for the wind industry. As the recent REN21 Renewables 2007 Global Status Report highlights, the industry broke all past global records, installing 5,244 megawatts (MW) of new wind energy capacity in 2007, or 30 percent of all new U.S. capacity added. This brings the cumulative national total close to 17,000 ...

  • The Future Cost of Wind Power

    Chapter 1 The economics of wind power Wind power is capital intensive with most of the investment required upfront. The largest capital cost component is the turbine itself which can account for between 40% and 80% of the total capital cost of an onshore wind installation. Costs offshore are higher because of the more expensive operating environment and the greater difficulty establishing ...


  • Renewable, clean energy: the petroleum footprint - wind farms under analysis

    This paper presents a methodology to assess projects for the generation of clean, renewable energy. Such methodology is applied here to estimate the consumption of fossil fuels (referred to as 'oil'), required for the construction, operation and maintenance of a wind farm consisting of 97 turbines of 3 MW each. Results show that such consumption represents a conservative 8–9% of the total energy ...

  • Wind turbine controlling of the future

    Higher, more robust, more reliable: Parallel to the growing requirements for wind turbines, the requirements for monitoring sensors grow as well. But how can wind sensor manufacturers fulfil these wishes? And how should a future wind sensors look like? After analysing the current conditions and trends on the wind energy market, our CEO Klaus Hirzel compiled a wish list for future wind sensors. ...

  • Eco-Brella: prototype development of the umbrella as harvester of solar and wind energies

    The familiar umbrella has been redesigned for power harvesting from renewable energy sources resulting in the Eco-Brella . Several engineering technologies are utilised: aerodynamics for fin design, mechatronics for power management, materials for thermoelectric and solar film, CAD for the layout, and heat transfer for human comfort. The result is a sustainable design capable of harvesting ...

  • Better grid interconnection essential for wind energy growth in Europe

    With a dramatic fall-off in government support for wind power in one of its superpower countries, Spain, Europe’s wind industry is concerned. Marc Height reports from Barcelona. From a wind industry leader to a focus of concern for the industry in Europe, things have changed in Spain pretty quickly. In January, the country made headlines by becoming the first in the world to source the ...

  • Sustainability in India through wind: a case study of Muppandal Wind Farm in India

    Sustainable development is closely associated with energy availability. It requires a continuous and efficient energy supply. Therefore renewable energy sources such as wind energy are vital for the Indian economy not only from supply side considerations but also for their environmental and social benefits. The current paper undertakes an empirical study of investments made at the Muppandal Wind ...

  • Energy and clean water coproduction in remote islands to face the intermittent character of wind energy

    In many small- or medium-sized remote islands, there is a significant electrical power shortage, where the water resources are quite limited. This unfavourable situation results in the operation of high cost autonomous thermal power stations and the transportation of fresh water of questionable quality at extremely high prices. Wind energy can definitely contribute on solving these problems at a ...

  • Competition in Wind Power, Outcomes for the future

    Without a doubt, wind power is taking the lead as not only a renewable energy with a much lessened environmental impact, but it is also edging out the competition from fossil fuels with the distinct ability to lessen the impact on the wallet. Fossil fuel consumption, headed by traditional fuel sources such as oil and natural gas, are falling to the way side as having a significant difference in ...

  • Wind power status, barriers, and opportunities

    In the wake of the oil crisis in the early 1970s, governments around the world were anxious to diversify energy supply away from fossil sources, and so harnessing the wind was seen as an important component of this policy initiative. A decade of research saw a Danish designemerge as the industry standard: the three-bladed, horizontal axis, upwind machine. A modern wind turbine comprises a tubular ...

  • EI enters offshore wind arena

    The G9 Offshore Wind Health and Safety Association (G9) was formed in 2012 to provide leadership on health and safety issues in the offshore wind industry. The G9 brings together nine of the world's largest renewable energy developers Centrica, DONG Energy E.ON. RWE Innogy. Scottish Power Renewables. SSE. Statkraft. Statoil and Vattenfall - to form a group that places health and safety at the ...

  • Animation: How Wind Turbines Work

    The windmill, which converts wind into rotational energy to mill grain or pump water, has been around since antiquity. It’s even been claimed that Ancient Babylonians planned to harness wind as early as almost 4,000 years ago, as part of a scheme for one of Hammurabi’s ambitious irrigation projects. By the end of the 19th century, wind energy took on a whole new meaning as engineers ...
