The United States further accelerates the developm

  • Detail

US President Barack Obama mentioned in his inaugural speech, "we will use the sun, wind and soil to provide energy for our cars and factories." In this regard, the US media believe that from these words, wind energy is likely to become one of the "troikas" in Obama's new energy plan. The United States is the world's largest energy consumer and the country with the strongest overall scientific and technological strength. The new president's statement will undoubtedly have an important impact on the research, development and application of wind energy technology

the American Wind Power Association (AWEA) recently disclosed that global wind energy surged by 28.8% in 2008. In 2008, the United States built 8.35gw of wind power generation capacity, which is 50% of the original capacity. The total capacity has now reached 25.1gw, accounting for one fifth of the global wind power generation, and has surpassed Germany's 23.9gw, becoming the world's largest wind power generation

schweicher, executive director of the American Wind Energy Association, said that in recent years, the development of wind energy has been paid more and more attention. It is expected that in 2009, American wind power will not only provide more new energy for American families, but also create more employment opportunities and become a new economic growth point in the United States

practice has proved that the charm of wind power is obvious, its energy cost is zero, its pollution emission is also zero, and the supply is sufficient. Mike pasgeletti, a professor of geography at Arizona State University in the United States, pointed out: "the wind energy in the Great Plains is very abundant. If it is fully developed, the potential wind energy in North Dakota, Texas and Kansas alone can meet the power demand of the whole United States."

investment in wind power generation increases

as the world continues to accelerate the process of seeking alternative energy, at least 1000 large-scale energy companies and investment companies in the world are optimistic about the bright future of wind power generation, and major wind turbine manufacturers around the world are also competing to invest, of which American entrepreneurs are the most active in investing in wind power generation

Ge recently announced that its investment in wind energy utilization will reach 5billion US dollars in the next 10 years. So far, the company has invested 6.5 billion US dollars in this field. Four years ago, General Electric bought its wind turbine manufacturing business from the bankruptcy property of Enron company. After all, it was a car company. As a result, GM expects revenue from wind turbine sales and maintenance to reach $2billion this year

California is the most developed region of wind power generation in the United States. At first, the state government adopted the tax exemption policy to encourage enterprises to build wind farms and develop wind energy. After years of promotion and development, wind farms have provided many employment opportunities and more taxes for California. Tihachapi is a small town in California and one of the three gale fields in California. Today, the US government has invested billions of dollars in the development of wind power every year. Tihachapi town is like the West in the past, reproducing the "gold rush" in California in 1849

fpl group has an annual revenue of US $9billion, and its power production department FPL energy is the number one wind farm owner in the United States. FPL energy has 43 wind farms in the United States, covering 15 states, accounting for about 40% of the wind power capacity in the United States. Last fall, Sino American energy began to build a wind farm in Iowa, which will become one of the largest wind farms in the world. In the past few years, the company has invested more than 2billion US dollars in the implementation of system management and performance appraisal without losing the warmth and energy projects

it is estimated that by 2020, wind power will account for 5% of the total power generation in the United States, and wind energy will also become a very important renewable energy in American daily life. According to the plan, by 2015, 10% of the utility electricity in Colorado must come from renewable energy, and wind energy is one of them. At present, schools, towns and some urban areas in eastern Colorado are using local wind energy resources

update wind power generation technology

in recent years, the wind power generation technology in the United States has made significant improvements, such as improving the design of wind turbine blades, widely using wind direction sensing elements, adopting automatic control systems, reducing manpower and reducing costs. Due to the adoption of new technologies, especially the application of new materials and electronic control systems, the installation cost of wind turbine power generation devices in the United States has dropped from $3700 per kilowatt in 1984 to $535 in 2003, and is expected to fall below $300 per kilowatt in 2010. In 1984, the cost of wind power generation in the United States was 20 cents per kilowatt hour. At present, it is 3 cents, which can compete with the cost of conventional power generation

the fans currently used are larger, more efficient and more stable than ever before. The 1.5MW wind turbine produced by general electric can meet the power needs of 460 households at the same time, with a height of 100 meters and a rotor length of 70 meters (longer than the wingspan of Boeing 747). Therefore, considering tax incentives, a standard wind turbine now costs only 3-4 cents per kilowatt hour of electricity, compared with 20 cents per kilowatt hour in the early 1980s. In some parts of the United States, this power generation method is quite competitive compared with coal or new natural gas power plants

the United States attaches great importance to the development of new wind turbines. 10 years ago, the power generation capacity of a single wind turbine was generally 50 kW, but now it has increased to 300-500 kW or even higher. In 2002, a wind turbine with a capacity of 600 kW was installed and put into use in Hawaii. At the same time, composite materials with high strength and light specific gravity have been widely used in the manufacture of fan blades. Some cutting-edge aviation and aerospace technologies have also been used in the fan system

according to US media reports, the US government is vigorously promoting the wind turbine manufacturing industry to make it an important basic energy equipment industry in the 21st century. It is predicted that before 2010, the United States and Europe will have a climax of wind turbine upgrading. At that time, a large number of old wind turbines will be eliminated. Therefore, the prospect of the wind turbine market is very optimistic

strong policy support

US President Barack Obama promised that despite the economic downturn, the government would continue to increase the tax cut for wind energy production to stimulate the development of wind energy. The goal is to make the price of wind power more affordable to the public with the support of preferential policies. At the same time, energy companies using wind energy can obtain a tax cut of 1.8% per kilowatt hour in the first 20 years of the project. A kilowatt hour of electricity is equivalent to 20 hours of electricity consumed by a 50 watt bulb. Experts believe that because the prices of coal and natural gas, the fuel of most power plants in the United States, are rising, wind energy as an alternative energy has become more attractive

last October, as part of the US $700billion financial emergency assistance act, the US Congress approved a tax relief plan to help the production and investment of the wind power industry and other new energy industries, and formed a law. The tax relief package stipulates that the new energy production tax relief will be extended for one year and the investment tax relief for eight years

insiders believe that the wind energy industry will also benefit greatly from the "renewable energy portfolio standard". Now, 17 states including California, Texas, New York and Massachusetts have adopted this standard. Although the specific contents of the standards vary from state to state, they all require utilities to purchase a certain proportion of electricity from renewable energy sources

according to the U.S. Department of energy, wind power will account for 20% of U.S. power demand by 2030, support 500000 jobs, reduce greenhouse gas emissions equivalent to 140million vehicles, and save 4trillion gallons of water. The American Wind Power Association predicts that in 2009, 60billion kilowatt hours of electricity generated by wind power in the United States will replace 91million barrels of oil, or 560billion cubic meters of natural gas, equivalent to 9% of gas-fired power generation in the United States

as wind power generation should first consider whether the installation of the main part of the experimental machine is the continuous decline of the vertical cost, wind power generation is increasingly showing its unique competitiveness. The American Wind Energy Association disclosed that at present, more than 220 companies in the United States have participated in a government led cooperation program. The goal of the program is to develop wind power generation equipment suitable for families. There are signs that more and more entrepreneurs now love wind energy, relevant energy cooperation projects are gradually increasing, and the competition among many multinational companies is becoming increasingly fierce
