At of the end of 2009, China's total installed hydropower capacity reached 197 million kilowatts.

China has the largest developing scale of new energy, if the large hydropower capacity is included.

While besides the hydropower, the amount of other new energy is quite small. In 2006, it was about 1.4%. In 2007, it grew up to 2%. And in 2008, it still didn't reach 3%.

As a whole, with the support of the government, China have been making great effort to the development of the new energy industry. And the new energy industry is becoming a new prosperous industry.

It is estimated that China has a large hilly area that is suitable for the growth of pistaciachinensis(an ideal material to make biofuels, which can meet the need of about 5 million biodiesel per year.

In recent years, for the influence of the rising petroleum cost and the global warming, global society has paid great attention to the development of new energy. Also with the support of policy, new energy industry enjoys a good growing environment.

The global wind power market expands greatly, the overall installed capacity has increased from 4800 MW in 1995 to 74223 MW in 2006, and it will be keep this good momentum in the feature.

In 2008, China had a newly increase wind power capacity about 12170 MW, and China has became the world 4th biggest market.

China has the world's largest industry scale both in installed capacity and manufacturing.

In 2008, global overall solar installed capacity had reached 15000 MW.

Till now, wind power development has become the hottest investment field.

With the background of the scarce fossil energy, all countries make great efforts to the solar energy industry, especially those developed countries, their early start makes them be the leaders in this field

At present, the industry of high tech crystalline silicon material, which is widely used in photovoltaic power generation field, has been monopolized by Japan, America and Germany.

The market of global solar battery is still managed by the minority of the manufactories like Sharp and Kyocera.

we can see that the solar power industries is a partly monopolized market.

Though China has the world's 4th biggest wind power market, it is still hard to enter its equipment field.

In China, the new wind power market will be divided by 3 business giants named Huarui Wind Power, Jinfeng Tech and Orient Electric.

Besides, the capacity of these 3 giant is keeping expanding. What's more, Vestas, a foreign manufactory also intended to extend their capacity.

2.3 GENERAL IDEA ABOUT BIO-ENERGY


Crop straw stalk, livestock manure, sugarcane, sweet sorghum, cassava, sweet potato, paddy hull, corn cob, bagasse are all sources of bio-energy.

Bio-energy is different from traditional energy, it can be renewable because it is made from corn. And those corn waste will be no more waste but useful if the bio-energy industry developed.

Bio-energy is easy to burn and the emission of SO 2 and nitrogen oxide is much lower than traditional energy.


Encourage and support the rural use of biomass for power construction in rural areas, increasing rural electricity supply

According to scientific planning and the principles of orderly development of land planted to encourage the use of non-energy plants, firewood and other energy forest to develop.

Encourage the production and use of biological liquid fuel. Oil Marketing Companies in the energy department under the State Council or provincial government requirements, should meet the national standard of biological liquid fuel into the fuel distribution system.

But with enzyme technology being mastered by more enterprises, it will be used much more often. And with the mature of engineering of microalgae method, its future may also become an important bio-diesel production technology trends.
