According to Huang Qili, the total wind energy resources in China are about 7-12 billion kilowatts. Land energy technology can develop wind energy resource reserves greater than that of the sea, and the annual power generation capacity can reach 1.4-2.4 trillion kwh. The area of ​​solar energy-rich areas occupies a total land area of ​​96. More than %, the solar energy absorbed by the surface every year is equivalent to about 1.7 trillion tons of standard coal energy; currently available biomass resources are about 290 million tons, mainly agricultural organic waste; the total amount of hydropower resources that can be developed is very rich, about About 600 million kilowatts, the nation’s hydropower technology can be developed at least over 500 million kilowatts, and the annual supply of electricity can reach 2.5 trillion kilowatt-hours.
Under the circumstances that China's total renewable energy resources are fully mapped out, Huang Qili and his project team have proposed such a strategic goal for China's renewable energy development: the strategic positioning of non-hydro renewable energy sources in the near-to-to-2010 timeframe. It is supplemental energy; in the medium term to around 2020, the strategic positioning of non-hydro renewable energy is alternative energy; long-term to 2030, the strategic positioning of non-hydro renewable energy is one of the mainstream energy; forward to around 2050 The strategic positioning of renewable energy is one of the dominant energy sources.
For China’s renewable energy development, Xu Kuangdi, dean of the Chinese Academy of Engineering, apparently also has a very deep understanding. After fully affirming the research and reports made by academician Huang Qili, he proposed to analyze the energy consumption of various renewable energy sources over the entire life cycle. “Renewable energy sources also consume chemical energy. For example, solar power is inseparable from polysilicon, but the power consumption of polysilicon wafers is much higher than that of the production of thermal power and hydropower equipment. Hydropower does not seem to consume energy, but the dam is With cement reinforced steel, the energy consumption for producing cement reinforcement is very high. When biomass power is generated, it is necessary to harvest the crop from the ground and send it to the place where it generates electricity. It also consumes diesel and gasoline."
In the use of solar energy, Xu Xiaodi raised a question worth pondering. He pointed out that at present all parts of the country are very active in the solar project, but a large number of polysilicon wafers produced have been exported to foreign countries, "putting pollution energy consumption in China, energy-saving applications on foreign countries, this issue needs attention."
"China's renewable energy resources have a large-scale resource base for development and can play a leading role in the future and even dominate the role of energy," said academician Huang Qili at the academic report of the Ninth Academician Assembly of the Chinese Academy of Engineering this morning.
