Between 2005 and 2008, the use of this form of energy doubled, with some countries basing up to 19% of its electricity production on Wind power (19% Denmark, 11 % Spain and 7 % in Ireland). Wind power really is exactly that, the use of wind turbines to harness the power of the wind and converting it in to useful energy.

Power transmission networks are generally connected to larger scale wind farms and use small turbines to provide isolated areas with electricity. These farms, where situated on agricultural land have one of the lowest impacts on the environment in comparison to other energy sources, but only produce approx 1.5% of the world electricity use despite its positive influence on the above listed countries.

Careful Planning is needed for Wind Power Plants. Just building a windmill in a windy place doesn’t mean that operating of wind power plant is simple. It’s necessary for wind power plant owners to plan carefully where to locate their machinery and also to check out that how fast and how much wind blows at proposed locations.

As it’s a rule that wind speed increases with altitude and over open areas that have no windbreaks. Good places for wind plants are the smooth rounded hills, open plains or shorelines and mountain gaps that produce wind funneling.

Wind Speed Variation

Throughout the United States wind speed varies and it also varies from season to season. As in Tehachapi, California, from April to October wind blows more than winter season. Wind blowing between those months is more because of the extreme heating of the Mojave Desert during the summer months. The hot air in desert rises and the cooler air from Pacific Ocean with great speed passes the Tehachapi Mountain to replace the vacuum. While in Montana State its totally different there wind blows more in winter.

Unfortunately, the UN climate summit ended today in Copenhagen, with a very weak global agreement, disappointing Britain, together with many other poor countries that were hoping for better results.

After extensive talks between 115 world leaders, and forming eight draft texts, the final decision was left in the hands of Barack Obama and Wen Jiabao, the Chinese premier.

The so-called Copenhagen accord “recognizes” the scientific need for keeping temperature rises to a maximum of 2C, but does not contain any strong commitments to the reduction in emissions in order to achieve the goal.

The American officials did try to call the deal as a “meaningful agreement”, but even President Obama declared that the progress was not enough, and that there is still a long way to go.

According to recent reports, scientists are working together progressively to develop an “artificial leaf” that imitates the working of a real leaf, i.e. the chemical magic done through photosynthesis.

However, instead of food for the plant, the new leaf converts sunlight and water into a liquid fuel such as methanol for cars and trucks.

The report came from top authorities on solar energy, who met at the 1st Annual Chemical Sciences and Society Symposium. The authorities stressed on initiating international cooperation and novel thinking on the global energy challenge.

In order to strengthen the two countries’ cooperation on renewable energy and energy efficiency, President Barack Obama and China’s President Hu Jintao have agreed to cooperate in organizing several programs and initiatives.

One of the key programs is to establish a U.S.-China Clean Energy Research Center, through an investment of $150 million in public and private funds over the next five years. The new centre will provide opportunities for joint research and development of clean energy technologies by scientists from both countries.

China is now facing the problem of how to combat the challenges of global warming. Being the world leader in both economic growth and carbon emissions, it is very hard for China to fight global warming, while simultaneously, not harming its robust economy.

The world’s biggest global exporter of manufactured goods, China, is also the world’s largest importer of tropical woods and the largest producer of cement. Although the benefits of China’s economic expansion have been great, the environmental impact has been immense too.

In 2006, it was discovered that all 10 of the world’s most polluted cities were in China.

On Friday Japan cautioned that if rich nations fail to make deep reduction as part of U.N. due deal in Copenhagen in December about greenhouse gas emissions then it could water down planned 2020 cuts in greenhouse gas emissions.

A draft report in Brussels shown that European Union states are preparing to approve or sign an estimate by the European Commission that developing countries will need about 100 billion Euros ($150.1 billion) annually by 2020 to tackle climate change.

To help developing nations to fight the global warming problem and disputes over 2020 emissions cuts by developed nations are the main hard points in slow moving U.N. talks which will end in Denmark on Dec.18 with a new treaty or agreement.

Japanese Environment Minister Sakihito Ozawa said that the possibility is not zero when he was asked if Japan might change its 2020 target of cutting emissions by 25 percent from 1990 levels if Copenhagen falls short on its determined target.

Although many won’t consider China as an environmentalist, but a growing green movement is underway in China’s industries, and according to some experts, China will probably leap ahead in renewable energy.

China is successfully changing its economic climate to greener side, especially in the form of green technologies like these wind turbines. For the last four years, China has doubled its wind energy capacity. This year, it will overtake the U.S. as the world’s top manufacturer of wind turbines.

First Solar Inc announced it plans to establish the world’s largest solar plant in China. It will be the first major foray by a US firm into the Asian nation’s fast developing alternative energy sector.

Following a memorandum of understanding with the Chinese government, First Solar will establish a 2-GW power station. It will be enough to supply energy to about 3 million Chinese families, at Ordos City, in Nei Monggol. The company will also further think about constructing a new manufacturing plant in China.

First Solar Inc., which is a U.S.-based renewable energy company, is going to build the world’s largest solar power plant in China as the country plans to increase electricity generation without pollution.

Dulce Qu, who is a Beijing-based spokeswoman for company, said by telephone today that the plant would be about thirty times larger as compared to the existing solar power stations that are operating in Europe. Arizona-based First Solar said yesterday that by 2019 the 2,000-megawatt complex will be built in Ordos City, Inner Mongolia, China, Tempe. One mega watt would be enough to power 800 U.S. homes.

China, which is the world’s biggest polluter, burns coal in order to produce 80% of the electricity consumed by them and wants at least 15% of the nation’s energy to come from renewable sources by 2020. The U.S. and China are making efforts for reducing emissions of gases blamed for global warming, and it has been reported by the New York Times yesterday that Bechtel Corp. plans to build a solar station in California.

Taiwan and China are the two giant players in wind power-generating equipment industry. In future they are keen to support each other in many industrial fields.

This was told by Huey-Ching Yeh, director of the Bureau of Energy under the Ministry of Economic Affairs (MOEA). He said that the Taiwan government hopes that Taiwan’s major suppliers producing wind power-generating equipment and services will
