The future of wind power

The practical limit to exploitation of wind power will be set by economic and environmental factors, since the resource available is far larger than any practical means to develop it.

This article covers the design of horizontal axis wind turbines (HAWT) since the majority of commercial turbines use this design. Contrary to popular belief, considerable attention should be given to the structural and foundation design of HAWTs. This is mainly due to the disproportionate amount that is spent on the foundations as a percentage of the total project cost.

2010 Deep Research Report on China Wind Turbine Nacelle Cover and Nose Cone Industry was published by QYResearch Wind Energy Research Center on May 2010. It was a professional and depth research report on China Wind Turbine Nacelle Cover and Nose Cone industry.

Wind Power Farm China

In 2009, China had only 63,000 kilowatts offshore wind turbines installed, about 21% of the newly installed offshore wind power in the United Kingdom the fastest growing country of the year. The year 2010 marked the start of China offshore wind power sector transition from research and pilot projects to operational wind farms.

Longyuan will set up a North American subsidiary, Longyuan Canada Renewables, to purchase about 70% of the project under development by Farm Owned Power (Melancthon).

So what is it? Well, it’s not just a wind company. Otter Tail is an electrical utility in the upper Midwest that has used it’s cash flow to create a diversified holding company that owns all kinds of businesses, from plastics to manufacturing to transportation and all kinds of other stuff. One of those companies is DMI Industries, a heavy steel manufacturing company which builds wind turbines. DMI did indeed up its production plans earlier this year to help meet demand, as teased in the ad (you can see the press release here if you like). The revenues from DMI make up far less than a quarter of total sales, though it is the fastest growing subsidiary and the core electrical utility is also investing in wind energy, as was teased using, one would assume, the towers built by their subsidiary.

The federal regulatory process can take months, sometimes more than a year. But Towner didn’t see anything until last week. That’s when enXco filed a draft plan on how the company would lessen the threat to birds at the wind farm. Towner says the company has indicated it is also working on the permit request, but so far nothing has been filed.

Wind Energy Xcel

According to the Annual Wind Industry Report for year-end 2008 published by the American Wind Energy Association (AWEA), Xcel Energy is the largest investor-owned wind power provider.

The new wind farm project will include approximately 40 miles of transmission in Lincoln, Elbert and Arapahoe counties in Colorado, and will interconnect to the electrical grid at the Missile Site Substation. The land for the 125 turbines and related equipment, plus a buffer zone, is roughly 35,000 acres. & 160;Construction will begin in early 2012, with an expected completion date in late 2012. The facility is expected to employ up to 250 workers at peak construction. The additional purchase of wind will give Xcel Energy in Colorado a total of 1,943 megawatts of wind generation on its system.

Wind is free, it& 39;s renewable and it& 39;s clean (unless you live in LA or Denver of course). In 2005, wind energy in the US produced 17.8 billion kWh per year or enough to power the city of Chicago. Unlike oil which continues to go up in price, advances in the turbine technology continue to reduce the per kWh cost of electricity produced by wind increasing its competitiveness. Wind is rapidly growing in favor and wind energy related stocks represent a great opportunity for astute, forward thinking investors. This page is dedicated to wind energy related companies.

Over the next 10 years, wind power generation is expected to exceed a 20% annual growth rate. With proponents such as T. Boone Pickens, there is strong support to help make this become a reality.

General Electric commanded 43% of the U.S. turbine market as of 2008, according to the Department of Energy, but wind power still isn t a large portion of GE s overall business. GE s total revenues for 2009 were $157 billion, with its GE Energy division contributing $37 billion. Wind turbine sales in 2009 were about $6.4 billion, Heymann says. GE has grown its wind-turbine business approximately tenfold since its initial purchase of Enron Wind Corporation s assets in 2002. Now the wind business is moving into a more steady, moderate growth environment, Heymann says. GE Energy has dominated the U.S. terrestrial turbine market, and is just now beginning to offer offshore turbines, but should regroup pretty quickly to capture this growing segment of the wind power market, he says.

Investing In Wind Power Stocks

REVE Wind reports that in Ohio over 7,500 skilled people are employed in manufacturing facilities such as production of gears, wind turbines blades and bearings related to wind power.

Last year, I wrote an article about the stocks of companies that are involved directly in the windmill, wind power and wind energy business. Unfortunately, most of them were either foreign companies or pink sheet stocks or both. However, there are many companies involved in the wind energy business on a peripheral basis, such as the manufacturers of the material used in windmill blades. Here are some wind energy related stocks, all of which have market caps over $900 million.

Wind Energy Companies Stock

One positive reason new wind power installations are on the decline is energy consumption has fallen in the past two years. Whether as a result of economic recession or energy awareness, consumers are using less power causing utilities to to look for less new capacity, including wind.

Future Of Wind Power

It’s amazing to think that wind power could actually be on the decline when the alternative energy sector seems to be just taking off in the United States. Wind power generation broke records in 2009 with 9.8 GW of new installation; however, this expansion of growth is slowing down dramatically as favorable sites are already taken and energy consumption has dropped in the US creating less demand.

Renewal was needed, and — bouyed by ‘green power’ initiatives in Colorado, Texas and elsewhere — U.S. wind energy development resumed in 1999, with a much broader geographical base.

The Future Of Wind Power Generation

Harnessing the wind is one of the cleanest, most sustainable ways to generate electricity. Wind power produces no toxic emissions and none of the heat trapping emissions that contribute to global warming. This, and the fact that wind power is one of the most abundant and increasingly cost-competitive energy resources, makes it a viable alternative to the fossil fuels that harm our health and threaten the environment.Wind energy is the fastest growing source of electricity in the world. In 2008, more than 27,000 megawatts (MW) of new capacity were installed worldwide. This stands as a 36 percent increase in annual additions compared with 2007, representing $51.5 billion in new investments.i The United States installed a record 8,500 MW of wind power in 2008, capable of producing enough electricity to power more than 2 million typical homes.ii In fact, in 2007 and 2008, more wind power was installed in the United States than in the previous 20 years combined a $27 billion investment. While wind energy accounted for just over 1 percent of both U.S. and global electricity generation in 2008, it already produces a large share of electricity in a number of leading U.S. states and other countries. Thanks to its many benefits, and significantly reduced costs, wind power is poised to play a major role as we move toward a sustainable energy future.The History of Wind PowerWind power is both old and new. From the sailing ships of the ancient Greeks, to the grain mills of pre-industrial Holland, to the latest high-tech wind turbines rising over the Minnesota prairie, humans have used the power of the wind for millennia.In the United States, the original heyday of wind was between 1870 and 1930, when thousands of farmers across the country used wind to pump water. Small electric wind turbines were used in rural areas as far back as the 1920s, and prototypes of larger machines were built in the 1940s. When the New Deal brought grid-connected electricity to the countryside, however, windmills lost out.Interest in wind power was reborn during the energy crises of the 1970s. Research by the U.S. Department of Energy (DOE) in the 1970s focused on large turbine designs, with funding going to major aerospace manufacturers. While these 2- and 3-MW machines proved mostly unsuccessful at the time, they did provide basic research on blade design and engineering principles.The modern wind era began in California in the 1980s. Between 1981 and 1986, small companies and entrepreneurs installed 15,000 medium-sized turbines, providing enough power for every resident of San Francisco. Pushed by the high cost of fossil fuels, a moratorium on nuclear power, and concern about environmental degradation, the state provided tax incentives to promote wind power. These, combined with federal tax incentives, helped the wind industry take off. After the tax credits expired in 1985, wind power continued to grow, although more slowly. Perhaps more important in slowing wind power’s growth was the decline in fossil fuel prices that occurred in the mid-1980s.In the early 1990s, improvements in technology resulting in increased turbine reliability and lower costs of production provided another boost for wind development. In addition, concern about global warming and the first Gulf War lead Congress to pass the Energy Policy Act of 1992 comprehensive energy legislation that included a new production tax credit for wind and biomass electricity. However, shortly thereafter, the electric utility industry began to anticipate a massive restructuring, where power suppliers would become competitors rather than protected monopolies. Investment in new power plants of all kinds fell drastically, especially for capital-intensive renewable energy technologies like wind. America’s largest wind company, Kenetech, declared bankruptcy in 1995, a victim of the sudden slowdown. It wasn’t until 1998 that the wind industry began to experience continuing growth in the United States, thanks in large part to federal tax incentives, state-level renewable energy requirements and incentives, and beginning in 2001 rising fossil fuel prices.While the wind industry grew substantially from the early 2000′s on, it suffered from a bout of boom-and-bust cycles due to the on-again, off-again nature of federal tax incentives. In 2006, a period of uninterrupted federal support for wind began, which has led to several years of record growth. In other parts of the world, particularly in Europe, wind has had more consistent, long-term support. As a result, European countries are currently capable of meeting more of their electricity demands through wind power with much less land area and resource potential compared with the United States. Denmark, for example, already meets about 20 percent of its electricity demand from wind power. Wind generation also accounts for about 13 percent of the national power needs in Spain, and 8 percent in Germany.iii Serious commitments to reducing global warming emissions, local development, and the determination to avoid fuel imports have been the primary drivers of wind power development in Europe.The Wind ResourceThe wind resource how fast it blows, how often, and when plays a significant role in its power generation cost. The power output from a wind turbine rises as a cube of wind speed. In other words, if wind speed doubles, the power output increases eight times. Therefore, higher-speed winds are more easily and inexpensively captured.Wind speeds are divided into seven classes with class one being the lowest, and class seven being the highest. A wind resource assessment evaluates the average wind speeds above a section of land (e.g. 50 meters high), and assigns that area a wind class. Wind turbines operate over a limited range of wind speeds. If the wind is too slow, they won’t be able to turn, and if too fast, they shut down to avoid being damaged. Wind speeds in classes three (6.7 7.4 meters per second (m/s)) and above are typically needed to economically generate power. Ideally, a wind turbine should be matched to the speed and frequency of the resource to maximize power production.
