into the city need policy support
Largest market for air conditioning and refrigeration, according to statistics, China\\ s to maintain accounts for the current two-thirds of the world, the world\\ s total annual output of 70% -80%, is the world\\ s super-solar water heater manufacture and use of power.
Largest market for air conditioning and refrigeration, according to statistics, China\\ s solar water heater to maintain accounts for the current two-thirds of the world, the world\\ s total annual output of 70%? 80%, is the world\\ s super-solar water heater manufacture and use of power.
At present, China has more than 2,800 manufacturers of solar water heater during the competition. In addition to Qinghua Sun, a few state-owned enterprises, the rest are private enterprises. Basically rely on the industry development and growth of private investment, the state almost no subsidies. China\\ s solar water heater industry has two outstanding advantages, first, the industry is market-oriented operation from start to finish, create a number of well-known brands, such as Emperor Ming, Qinghua Sun, Norit, sun, rain, etc.; second, with full proprietary advanced technology, such as vacuum tube collector technology.
In 2009, China\\ s solar water heater production of 42 million square meters, population reached 145 million square meters of solar water heaters based on the heat gain per square meter per year is equivalent to 417 kwh power calculation, 145 million square meters of ownership means that you can replace 604.65 one hundred million kwh electricity. 2009 total national power generation of 3.6 billion kwh, of which wind power capacity is 270 billion kWh. Contrast can be seen, solar water heaters in the share of renewable energy component of the weight. However, the Government in clean energy consumption by 2020, accounting for 15% of the target, the development of renewable energy, solar thermal support is not enough.
The world\\ s major developed countries to achieve industrialization, continue to lower its industrial energy consumption, construction and transportation energy consumption is increasing. The future, our country\\ s industrialization and urbanization, the energy consumption will gradually shift to the construction and transportation fields. If you can not scientific and reasonable utilization of energy, it is very likely used in daily life and the struggle between industrial and agricultural use to the conflict. We can not only to improve living standards, but also consume a lot of fossil fuels, over-reliance on energy imports, which will cause a very serious problem, and even lead to international disputes.
Low-temperature heat utilization is to reduce building energy consumption is very important part, such as heating, cooling, domestic hot water, all of which can use solar thermal energy solutions, which is energy saving is significant. Government\\ s energy strategy should attach great importance to solar thermal applications, in particular the development of low-temperature heat utilization, enhance their technical content, to promote building energy integration.
\"Renewable Energy Law\" provides that the State encourages units and individuals to use solar water heaters. However, China does not enforce the policy of solar water heater installation. Israel and Japan, due to relatively poor living conditions, lack of resources, population is concentrated, have developed a number of national conditions from energy policy, development of energy-saving technology. Israel is the first country to introduce legislation to force the country to install solar water heaters.
China\\ s solar thermal technology is relatively mature, low cost products, can achieve through the policy of mandatory installation of building energy efficiency. Implementation of building energy efficiency must start from the government to play a leading role model. If the Government does not participate alone company, the people to implement, ineffective.
At present, China Beijing, Shanghai and other big cities because of too many problems left by history of urban construction, the Building Energy Saving very difficult. However, some new small and medium sized cities, must be in the planning, to include building energy efficiency into. Such as Sun City, Shandong Dezhou is known, the new residential and public buildings to promote the use of solar water heaters rate has reached 90%.
