China's Public Buildings Will Force the Introduction of Solar PV Systems

Last year, China's GDP exceeded Japan and became the second largest economy in the world, but its energy consumption was five times that of Japan. China and the United States have almost equal total energy consumption, but GDP is only a little over a third of the United States. . The “2011 China New Energy Summit Forum” organized by Shanghai Jiao Tong University’s Antai College of Economics and Management was held on December 1. Shi Lishan, Deputy Director of the New Energy and Renewable Energy Division of the National Energy Administration, used the above group The data shows that in terms of the rational use of energy, there is still much room for improvement in China's technology and management.

According to the “Twelfth Five-Year Plan”, by 2020, new energy sources, including solar photovoltaic, wind energy, and biomass energy, will account for 20% of China’s total energy consumption.

Shi Lishan said that China's current energy management system and system still uses conventional controllable energy as the main target. In the energy dispatching and equipment operation, the disadvantages of non-continuous and low density of renewable energy such as wind power have not been fully considered. How to integrate becomes a difficult point. “The development of new energy is not just breaking the technical bottleneck, but renovating the existing energy system and reconstructing the modern energy system from theory and technology.”

China has rich solar energy resources and solar photovoltaic is also considered as one of the most promising new energy industries. Shi Lishan disclosed yesterday that China will actively promote solar photovoltaic systems combined with buildings in the future. In fact, subsidies for solar water heaters have always been the difficulty in designing price subsidies. To continue to promote and improve the efficiency of solar energy use, in the future, hospitals, schools, hotels and other public buildings may be mandatory to introduce solar thermal systems at the design stage. Solar photovoltaics will become part of the building.
