Researched and compiled by the Social Development Research Center of the Chinese Academy of Social Sciences, the Urban Development Institute of Gansu Province, and the Lanzhou City College, edited by the Social Science Literature Press, edited by Sun Weiping and Liu Juke, “Eco-city Green Paper—China Ecological City Construction and Development Report 2013) came out recently.
The report pointed out that China should accurately find out the crux of the construction of eco-city and the development and utilization of green energy, and grasp development strategies. This is the primary condition for the healthy development of ecological cities. Although great achievements have been made in the development of urban green energy in China in recent years, there are still some problems that hinder the development of ecological cities to some extent. The report shows that there are five major problems in the development of urban green energy in China.
First of all, the production scale of solar water heaters is not small, but there are problems of low-level redundant construction and similarities. Really excellent quality, especially in combination with construction, is very rare. In addition, its basic research investment is low, the research team is very weak, and the atmosphere for intensive research is not strong.
Secondly, there are many problems in the research and industrialization of solar building integration, such as the development of design software and the components, functionalization, standardization, modularization and industrialization of various solar thermal photovoltaic buildings. Only a handful of institutions of higher learning and scientific research institutions are engaged in the research and promotion of solar energy technology. A large number of design units and architects have not yet participated in this work. These units and architects are not well aware of the principles and design methods of solar energy utilization. They lack awareness of the significance of energy conservation. They do not consciously design according to the principles and methods of using solar energy. They do not consider the use of solar energy as a part of the building and cause the building to During the civil construction period, no suitable embedded parts were installed, which caused certain obstacles to the installation of solar energy devices in the future.
Third, in terms of photoelectric conversion and utilization of solar energy, China has only conducted some basic research from the perspective of scientific research. Compared with foreign industrialized countries, there is still room for improvement in the breadth and depth of research on photovoltaic applications in China.
Fourth, in the research and development of wind energy technology, the biggest problem China currently faces is that it still does not have the manufacturing technology and capabilities of key components of large-scale wind turbines, and has always relied on the introduction of foreign equipment and technologies. In addition, in the wind turbine system design and system control, China still needs a lot of research.
Fifth, in the use of geothermal energy, China has just started, geothermal energy is only used in some areas and areas, and the level of application needs to be improved. The scale needs to be gradually expanded.
