Cheng Siwei: new energy development is still a lack of careful and meticulous planning
Development of new energy is a very important measure to achieve a low-carbon economy. China's new energy development trend is encouraging, but also faces severe challenges. The challenge in the following areas:
First, the current for the development of the new energy, the country still lacks a thorough and meticulous planning.
Second, we also lack a key technology in the new energy innovation. For example, the second generation of solar technology is no crystalline silicon thin film technology, we are mainly imported; wind generator is now the largest in the world can do is 5 MW, our country can do is 1.5-2.5 MW, 3 MW just off the assembly line, some of the key components we can not manufacture; electric car battery problem is also not a breakthrough. Questions like these are a reminder that we must strengthen the independent innovation in new energy. No innovation, our new energy can become a big country, but can not become a powerhouse.
Third, the new energy costs are generally higher. Wind power cost than twice as high thermal power; solar thermal power generation cost is four times.
Fourth, the development of new energy must be encouraged to go, keep calm and avoid speculation. Once too much hype, and certainly there are some companies to pursue short-term interests, and even issued some false information, which will reduce the people's confidence in the development of new energy sources.
I think that the development of new energy sources, should solve the problem on three levels:
The first level is the technical level. Must be through a combination of innovation and the introduction of a breakthrough in technology. This breakthrough has two categories, one short-term, the recent, one is long term. For example, wind energy, we can break the recent automatic control technology, manufacturing technology of key components, 5-megawatt generator production technology. But in the long run, the old by natural wind, still dependent on the weather. In the study, now someone chimney technology, if engaged in a chimney, drawing air through the chimney, the use of artificial wind to generate electricity, there is no problem by days.
The second level is the economic level. Now the high cost of new energy sources, how to do? One is to be reduced by the cost of a breakthrough technology; second is to calculate the environmental costs through new energy to give certain subsidies; Third, through the now internationally called Clean Development Mechanism (CDM), to get some compensation; Fourth enterprise to consider how to optimize the supply chain, in order to increase the added value.
The third level is the political level. Development of low-carbon economy, the development of new energy, climate change, definitely not a country they can do, and this is a worldwide problem, so we need to strengthen international cooperation, which need to solve this problem politically.
Copenhagen Climate Conference held recently, Premier Wen Jiabao at the conference comprehensively expounded China achievements and future goals in terms of energy saving has been achieved. Historical cumulative emissions in developed countries is a major, China's total emissions account for only 9 percent in history, we are now only about per capita emissions of the average American is 1/4. When I met together at Davos and the international chemical industry giant told them that they were moving production to come to us, the row count of carbon dioxide in our heads, we blame, but you get a good reputation, it is unreasonable the.
China is a developing country, development is impossible not to an increase in industrial production, could not increase carbon dioxide emissions. Of course, we are not as a reason to lighten their responsibilities, but also make it clear that developing and developed countries there is a difference. China's sustainable development and new energy development will continue to make progress, to achieve a low-carbon economy and ecological civilization will be far off.
