China’s Biomass Energy

China leads the world in its energy reservation and is the second largest energy producer and consumer in the world. It is estimated that China has 4000 billion tons of potential primary energy reservation. However, per capita energy resource quantity and consuming quantity is far smaller than the world average level. The main characteristics of China’s energy exploration and utilization are as follows.

1. Coal is the primary energy; exploration and utilization of renewable resources is supplementary. China’s explored reserves of coal resource accounts for over 90% of the primary energy total, such as coal, oil, natural gas, water energy and nuclear energy. Coal is dominant id China’s energy production and consumption.

on.

2. Energy consumption volume is increasing while energy utilization efficiency is comparatively low. As the economic scale expands, China’s energy consumption is on the constant increase. Under the influences of capital, technology, energy price, etc, China’s energy utilization efficiency is far lower than that of the developed countries. Energy comprehensive utilization efficiency is 32% and the overall energy systematic efficiency 9.3%. These numbers are only half of the developed country level.

3. With the sustained increase of energy consumption, the coal-dominant energy structure has caused urban air pollution while with the excessive consumption of bio-mass energy giving rise to ecological destruction, the pressure on ecological environment is more and more severe. According to the World Bank, the economic loss caused by air and water pollution in China, approximately accounts for 3%--8% of GNP.

4. The energy structure is getting more and more pluralized. By the middle of the 1990’s, energy self-sufficiency rate was 98%, while at present China is the second largest crude oil importer only after USA.

The rapid development of China’s economy is based on the sufficient supply of energy, however, the higher-than-normal oil price on the international market together wit h China’s ever-increasing energy demand will be a serious subject faced with

China’s development road.

More than 3200 places of terrestrial heat have been discovered in China, 225 of them could be used for power generation. It is estimated that the exploitable reserve of terrestrial heat in China is equal to the power of 462.65 billion tons of standard coal. In recent years, the use of terrestrial heat in our country has increased by 7%. We have used

China will adopt the sustainable energy development str ategy of an “energy saving prioritized, plural structured, and environment friendly” nature in the coming 20 years. We will adopt the international energy strategy and strive to quadruple GDP with double energy consumption with the help of mechanism innovation and technological advancement. The following specific goals are expected to reach under the sustained energy development strategy: energy consumption of per unit GNP will be reduced by 20% on the level of the end of the 10th five-year plan; primary energy demand will be less than 2.5 billion tons of standard coal by 2020, saving 0.8 billion tons; coal consumption ratio is controlled under 60%, renewable energy utilization reaches 525 million standard coal (power generation by renewable energy stands at 100 million kilowatt); oil importing reliance is controlled under around 60%; the reduction rate of main pollutants is 45%--60%.

The Development of New Energy in China

New energy and renewable energy only started to develop in China. As pointed out in the Annual Report of China’s New Energy Industry released in January, 2007, China will largely increase the rate of new energy such as wind power, solar power, and biomass power in the overall energy consumption. The report says, our first step is; the new energy installed capacity will be 120 million kw by 2020, that is 12% of China’s total installed power capacity. We will have a boost of power generation by using wind, bio-energy and solar energy. The second step is; the percentage of new energy consumption will increased dramatically comparing to other kind of energies. By 2050, the new energy will account for 30%--40% of the total energy demand of China. Now l would like to give you a brief introduction on wind power, biomass energy, solar energy and terrestrial energy in China.
