We all know in 2008 the companies in the solar energy industry suffer the ache from the global financial crisis. Some companies closed a few production line of solar power. This is even worse in China. Nowadays China has played an important role in the field of solar energy. But the government of China has tried to stimulate the solar energy industry.

Chinese government started the “Golden Sun” subsidies  on Jul 21, 2009 to provide subsidies to solar-power projects, to boost the solar industry as a new growth point for the country’s economy.

The Ministry of Finance of China said on its website that it will offer 50 percent of investments for solar power projects of more than 500 megawatts (mw), and the transmission and distribution network over the next 2 - 3 years.

The solar power projects in the remote regions of China that are not connected to the electricity grid will receive subsidies of 70 percent of the investment.

We show potential of geothermal power in the world below.

If heat recovered by ground source heat pumps is included, the non-electric generating capacity of geothermal power (geothermal energy) is estimated at more than 100 GW (gigawatts of thermal power). This geothermal power is used commercially in over 70 countries.

During 2005, contracts of utilizing geothermal energy were placed for an additional 0.5 GW (gigawatts) of capacity in the United States, while there were also plants, which are under construction in 11 other countries.

Estimates of exploitable worldwide geothermal energy resources vary considerably. According to a study of 1999, it was thought that this might amount to between 65 and 138 GW of electrical generation capacity 'using enhanced technology'.

As one kind of alternative energy, geothermal power has many advantages such as requires no fuel, and is therefore virtually emissions free and insusceptible to fluctuations in fuel cost. Read this articles for more advantages and details of geothermal power. There are a few disadvantages of geothermal power.

From the perspective of engineering, the geothermal fluid is corrosive and, worse, is at a low temperature, compared to steam from boilers. And by the laws of thermodynamics this low temperature of the geothermal fluid limits the efficiency of heat engines in extracting useful energy during the generation of electricity. Much of the heat energy is lost, unless there is also a local use for low-temperature heat, such as greenhouses, timber mills, and district heating.

The development of wind energy in China has been put on the fast road. Many companies have focused on wind energy. Much money has been invested on the project of wind energy (wind power). Is it good news? is it a miracle for green energy (alternative energy)? or just an investment bubble on wind power?

The western areas of China, such as Gansu, Inner Mongolia is rich for the resource of wind energy. Meanwhile, these areas are poor. If these investment on wind energy in these poor areas is just to develop the green energy (renewable energy, alternative energy), not an investment bubble, surely, it will stimulate the development of these areas and will bring many benefits to the people living in those areas, such as solving the employment, making them richer (or exactly not so poor).

Advantages of Geothermal power

Geothermal power requires no fuel, and is therefore virtually emissions free and insusceptible to fluctuations in fuel cost.

And because the geothermal power station doesn't rely on transient sources of energy, unlike, for example, wind turbines or solar panels, its capacity factor can be quite large; almost up to 90% in practice.

Geothermal power (geothermal energy) is considered to be sustainable because the heat extraction is small compared to the size of the heat reservoir.

Geothermal has minimal land use requirements.

What's geothermal power (geothermal energy)? From geothermal, comes from the Greek roots geo, meaning earth. And thermos, meaning heat. That's the meaning of geothermal power. Geothermal power is energy generated from heat stored in our earth, or the collection of absorbed heat derived from underground.

The Philippines and Iceland are the only countries to generate a significant percentage of their electricity from geothermal power sources; in both countries 15-20% of power comes from geothermal plants.

As all of us know, China is currently in a phase of rapid industrialisation and integration into the world economy. But unfortunately this has come at a high price, putting great strain on the environment through extensive use of fossil fuels and other natural resources. The difference in living standards between urban and rural areas – and between the east and west of the country – has also widened, and unemployment is rising fast.

Many are concerned that China’s long-term prosperity could be harmed by increasing social inequality and conflicts resulting from environmental pressures and eco-system degradation.

Bioenergy development has become a top government priority, and China’s law on renewable energy (alternative energy, green energy) was implemented earlier (in January 2006).

The current focus is on electricity generation from surplus agricultural residues, which are estimated at 200 million tonnes yearly. The government has set up a long-term target of 30 gigawatts of electricity generated from biomass by 2020, which will require billions of US dollars in investment. And there is also a growing interest in the development of biofuels such as biodiesel and ethanol, intended to reduce oil imports, which currently account for more than 46% of China’s total oil supply – a major energy security concern for the government.

As one kind of green energy (alternative energy, renewable energy) source, bioenergy will account for one percent of China's renewable energy (alternative energy) consumption by 2010, and four per cent by 2020, some officials predicted some year ago.
 
Bio-energy strategic development in rural China will help China meet the rising demands for energy (power). 

In fact developing bio-energy in rural China will promote the development of the agriculture, rural areas and the farmers in China. 

In our last article about wind power market in the US, the US wind energy market will see a surge in 2010. And some researches show that China could at least double its current wind energy (wind power) target for 2020.

A few years ago, Energy Bureau Director of the National Development and Reform Commission (NDRC), Xu Dingming said: “The development of renewable energy plays a crucial strategic role in the power supply of China. Wind energy growth in China is now on a fast track and globally we believe that wind power will become the primary alternative energy in the future.”

According to one report, China’s current wind energy (wind power) plan is to reach 20 Gigawatts (GW) by 2020. And we know that Germany, the world wind energy leader today, has just under 17GW. But the experts within the Chinese wind energy industry believe that 40 Gigawatts (GW) can be delivered in 2020; rising to ten times this by 2050. This scale of wind power would need 20,000 typical modern wind turbines by 2020. The investment generated could be worth USD 40 billion; putting China on track to become the world’s biggest wind energy market by 2020.

Let's put our eyes on China's total wind energy resources.

The capacity of wind potential in viable windy locations in China is large enough.
