Looking at the fierce decline in the prices of global photovoltaic products, successively encountered European debt, US anti-dumping countervailing anti-subsidy "double reverse" lawsuit, making nearly 90% of Chinese PV products sold abroad are in a more difficult situation. Photovoltaic polysilicon, wind power equipment and other industries are experiencing overcapacity, and people feel that the new energy industry has become more competitive.
When it comes to new energy, almost everyone will focus on photovoltaic and wind power industries. Thanks to the introduction of the "Solar Roof Project" and "Golden Sun Project", China's photovoltaic industry has been advancing rapidly. The output of photovoltaic cells alone has reached 2.5 million kilowatts, ranking first in the world. According to incomplete statistics, as of the first half of this year, the national polysilicon production capacity has exceeded 220,000 tons/year, and in 2012, the world's estimated demand is less than 100,000 tons. The hot-hot numbers spelled out an awkward picture and planted seeds for “overcapacityâ€...
However, in the “high fever†of new energy industry, the urban biological regeneration resource system has not attracted enough attention. The bioenergy production enterprises are in awkward position. What kind of role can bioenergy play in energy scarce China?
Bioenergy is widely found in humans, plants, animals and their excreta, garbage, and organic wastewater. Due to the huge number of organisms in the world, the energy contained in it is also quite alarming.
On the one hand, like solar energy and wind energy, biological resources are renewable and “inexhaustibleâ€. The development of bio-renewable energy will play a significant role in alleviating energy shortages in China, and will form a good complementary pattern with other new energy industries. On the other hand, the use of bio-energy will not only damage the ecological environment, but also effectively improve the environment. The status of serious pollution.
Experts point out that there are also a large number of wastes that can be converted into bio-energy and resources in the cities. Food kitchen waste oil after dehydration and impurity removal, high purity, is the best raw material for biodiesel.
Compared with conventional diesel, biodiesel can reduce carbon monoxide by 90%, total suspended particulates by 80%, and carbon dioxide emissions by 78% without sulfide emissions. 100,000 tons of biodiesel can save 128,600 tons of coal, save 1,046 million kWh of electricity, and replace 90,000 tons of oil. The energy efficiency is very alarming. For densely populated big cities, the scale of such transformation is huge.
Regrettably, statistics show that with the acceleration of urbanization, the number of urban organic waste has increased sharply, and the processing rate has been “downhill†year after year.
The data shows that in 2007, the annual output of biodiesel was 3 million tons. By the third quarter of 2011, this figure had dropped to 300,000 tons. Among them, problems such as immature technology, profit-driven influences, and people's restrictions on traditional ideas, and feeling that waste recycling is difficult to achieve are all bottlenecks that need to be addressed.
Faced with the dilemma of bio-energy, the government must dare to lift its scalpel. Only when it is a circular economy and sustainable development will the government enter a “dead endâ€.
Similar to the photovoltaic and wind power industries, bioenergy has not yet reached the stage of large-scale expansion of the market. In terms of policy-driven, it is also behind other new energy industries. The road to expansion is not smooth. However, compared to the fierce competition created by the enthusiasm of wind power, solar energy and other industries, the transformation project of biological renewable resources is like a blue ocean.
In terms of upgrading new energy technologies, it is also necessary for the country to consider "one game of chess." The state should strengthen research and development of new energy basic theories, increase investment in research funding for the development and use of new energy, establish a "state-level" strategic technology reserve, and gradually reduce its dependence on foreign new energy technologies. Of course, whether this road can go further and wider depends on the improvement of people's ecological concepts and the level of awareness of waste regeneration.
