The recent heavy snow so that natural gas demand throughout Laptop Battery the surge, while the supply side, said every effort had been still can not meet the demand, which leads to many parts of the country a "gas shortage" in some cities the gap even up to 40%.
Like encounter "power shortage", "Oil Shortage", as this explanation of "gas shortage" causes are: extreme weather events leading to the demand surge, resulting in short supply. However, in the contradiction between supply and demand behind it reflects the one-time resource bottleneck. Grid can be built, wells can play, the trachea can shop, but it is a one-time non-renewable resources. If the gas exhausted, and the trachea shop had to pay a long, what for?

Of natural gas because of its low-cost, clean, environmentally friendly features have been a lot of promoting the use of, but as a primary energy dell 312-0625 battery, natural gas reserves are limited. At present, natural gas, more than 400 billion cubic meters of annual output is only about China's energy production in less than 5%. Data show that China's total gas reserves of natural gas in the world in less than 3%.

This, the authorities urged the public should be saving gas. Of course, energy-saving responsibility, but both require the production or the life of the use of energy, so the use of energy, in addition to reducing expenditure have to open source.

To seek resources abroad is one way to succeed. In recent years, China actively with the countries in the world to carry out oil and gas cooperation, from Saudi Arabia, Russia to Venezuela and Brazil, China Petroleum, Sinopec to learn the world's oil pipelines, are from the Middle East to North Asia, dell 0XR693 battery South America extended.

"However, only a simple response to the issue of energy imports to rely on other countries is not a fundamental way. For the most populous country like China, the world in any one country can not provide adequate supply. In the final analysis, to solve the energy crisis have to rely on myself." Executive Dean of Institute of World Energy Finance, China Financial Research Institute, said Mr Ho Sai-Hung, China's conventional energy resources is only 60% of the world's average, in order to meet growing energy needs, we must accelerate the development and utilization of new energy, which is to solve the problem the key.

Wind resources in China is rich in wind energy development and utilization of available reserves of 10 million kilowatts. At the same time, has a very rich solar energy resources in the Northeast, Midwest, North China are large amount of solar radiation. And in the geothermal field, according to estimates, China's major sedimentary basin geothermal energy stored in dell XR693 battery 736 Yiyi Qian J, exploitable geothermal resources in the country amounted to 6.8 billion cubic meters annually, equivalent to 32.84 million tons of standard coal each year generating capacity.

Not long ago, Obama said during his visit, the two sides agreed to strengthen the clean air, water, transport, power and resource protection cooperation and signed a "China Science and Technology, National Energy Bureau and the U.S. Department of Energy on the Clean Energy Research Center of China-US Joint Protocol on Cooperation, "the future of the two sides will invest at least 150 million U.S. dollars for clean energy research.

In fact, new energy development and utilization of our country dell RN873 battery there are still insufficient. According to the National Energy Board data show that in 2008 China's primary energy consumption, composition, coal will still account for 69% of the proportion of wind power, solar, nuclear and other new energy sources share of less than 2%.

"The new energy in the whole society negligible amount, which is non-fossil energy sources by 2020, accounting for the proportion of primary energy consumption reached about 15% of the target is still a considerable distance." Li Junfeng, deputy director of NDRC Energy Research Institute, said, "The new energy industry also need to give government and community dell GW240 battery understanding and support. "

China Renewable Energy Society for Shi Dinghuan that the new energy capacity to adjust to play the basic role of market regulation, while strengthening the government's macroeconomic regulation and control. Government needs to help companies build technology research and development platform that supports R & D and production and research integration and to develop new energy future, large-scale development can adapt to a variety of technical and management Dell HP297 battery personnel.
