1. Introduction   

Energy is significant to our life. We use it in our daily life. We can not live without it.

Energy is used directly and converted to supply light, heat and power for human beings. With the high-speed economy and technology development, more and more types of energy appear. Meanwhile, energy is used in more and more areas of society.

Energy plays an important role in Xinjiang’s development. Xinjiang is rich in energy resources such as solar, wind power, petroleum, natural gas and coal. Besides, Xinjiang also has many mineral resources, such as, iron, copper, nickel and jade (stone for ornaments).

year by year, but the percentage of natural gas, hydropower and wind power is small, which is due to relatively immature technology and limited natural source. And from 1980 to 2005 the coal’s percentage of total energy production decreased because natural gas is rich in Xinjiang and its reserves ranked first in the country. In recent years, Xinjiang increases the efforts to develop and widely use natural gas. Additionally, the price is lower than coal, therefore, because of the promotion of natural gas, the coal’s percentage in total energy production decreased accordingly at that time.

From Table 4 , we can see that from 1978 to 2005 the total energy consumption also increased year by year, since coal could be used in many places. It occupies a big percentage, because the population in

Xinjiang is not very big, so the percentage of crude oil, natural gas, hydropower and wind power are not so big.

c) Data on imports include the petroleum consumed by the Xinjiang airplanes in refueling abroad. Data on exports include the petroleum consumed by the foreign airplanes in refueling in Xinjiang

Some explanation in Table5:

Final energy consumption: it refers to the total energy consumption by material production sector, non material production sector and households in the province in a given period, but excludes the consumption in conversion of the primary energy into the secondary energy and the loss in the process of energy conversion[1].

Loss during the process of energy conversion: it refers to the total input of various kinds of energy for conversion, minus the total output of various kinds of energy in the province in a given period. It is an indicator to show the loss that occurs during the process of energy conversion . [1]

Loss: it refers to the total loss of energy during the course of energy transport, distribution and storage, and the loss caused by any objective reason in a given period. The loss of various kinds of gas due to gas discharges stocktaking is excluded[1].

Here is some explanation about elasticity ratio of energy[1],

Elasticity ratio of energy production is an indicator to show the

relationship between the growth rate of energy production and the growth rate of national economy. The formula is:

The average growth rate of national economy can be shown by the gross national product, gross domestic product and other indicators, depending upon the purposes or needs. The gross domestic product is used in calculation of the ratio.

(16)

Elasticity ratio of energy consumption is an indicator to show the

relationships between the growth rate of energy consumption and the growth rate of national economy. The formula is:

Elasticity ratio of electricity production is an indicator to show the

relationship between the growth rate of electricity production and the growth rate of national economy. Generally speaking, the growth rate of electricity production should be higher than that of national

economy. The formula is:

Elasticity ratio of electricity consumption is an indicator to show

the relationship between the growth rate of electricity consumption and the growth rate of national economy. The formula is:

According to the tables above, we can have some basic ideas of the situation of energy in Xinjiang. From the tables and figure we can find the total energy production is growing year by year.

(17)

3.1.2 Problems  (1) The impact of coal’s high consumption

Because coal is a unique advantageous resources of Xinjiang, it is still the main energy consumption, and the industries are still the major groups of coal consumers. Then, the pollution from coal combustion is serious in Xinjiang.

(2) The development of oil and gas is restricted in Xinjiang

The natural gas is limited demand for market in Xinjiang. The reasons include nature, history and society, and Xinjiang’s

economic development is slow, existing facilities can not meet the demand of Sinotrans (China National Heavy Machinery Corp).

3.2 Non‐productive consumption 

Non-productive consumption means the energy consumption used by residence, commerce, and other sectors which are not producer. The consumptions of each resource are shown in the following tables[1].

(18)

~ 18 ~

From the above tables, we can find that compared with other consumptions, the consumptions of coal, electricity, and natural gas are so similar, the coal used in Xinjiang has large proportion in the total non-productive consumptions as in the total energy consumption.

(20)

3.3 Coal in Xinjiang 

Xinjiang’s coal reserves are the richest in China, according to the survey, the estimated coal reserves are 1.82 to 2.19 trillion tons[2 in

2006. Xinjiang is one of the important mining area and the coal reserves can reach 40.5% of the forecast of the whole country reserves. The resource distribution is shown in the following figure .

chemical energy that is stored within this resource. All fossil fuels are nonrenewable resources.

Xinjiang is a province with rich Petroleum resource. 1/3 of China’s Petroleum is here. The main areas of petroleum in Xinjiang are Karama and Zepce (Southwest). Recently, in Tarim and Turpan - Hami Basin have been found many oil fields and Junggar Basin also has been found to have new oil fields. Xinjiang has become a county of oil and natural gas reserve base. The figure below shows the areas with petroleum resources[20].

Figure 3 the petroleum distribution in Xinjiang [20]

Some advantages of Petroleum

~ 21 ~ 

• Petroleum is the most versatile fossil fuel. Yielding a vast

(22)

• Petroleum is relatively easier to be stored and transported

between source and end users. The fact that it is liquid form means it can be pumped through pipelines where possible and containerized where it is not possible.

• Petroleum is cleaner and easier to burn than coal. • Electricity produced from Petroleum is reliable. Some disadvantages of petroleum

• Petroleum is a carbon-based fuel and the primary way it is

used is to burn it, releasing more than its weight in CO2 because of the added oxygen. CO2 is a greenhouse gas and is expected by most scientists to be a cause of global warming[21] • Some petroleum is now being strip mined in the form of tar

sands. This cause the area very hard to restore. [2 1]

4. Electricity   

4.1 Electricity Generation   

The total capacity of the power stations in Xinjiang reached 47.74 million kW in 2007. Specifically, Dabancheng Wind Power Station is one of the biggest stations in the China, and also is the biggest wind power station in Asia. Xinjiang is fully using wind power resources, and wind power generation in Xinjiang will become an important alternative energy in the future. The following table shows some power station and electricity generation capacity in Xinjiang .

2. Different parts have different prices, which are determined by the development of China's national conditions and the development of China’s electric bureau.

(27)

5. Renewable Energy 

Renewable energy refers to energy resources that occur naturally and can repeat in the environment and have benefits to human beings. Examples of renewable energies include solar energy, wind power, biomass and geothermal energy (getting energy from the heat in the earth).

Renewable energy encompasses many different types of technologies at different stages of development and commercialization, from the burning of wood for heat in the residential sector (traditional and low-technology) to wind-generated electricity (widespread and technically practical) to processes such as biomass gasification for electricity generation (still under development although some plants are operating). Xinjiang is the place with abundant renewable energy. [22 ]

5.1 Solar Energy in Xinjiang 

~ 27 ~ 

Xinjiang is characterized by arid climate. The sunshine hours are 2550[8 to 3500 hours in the whole year and sunshine percentage

is 60%[8 to 80% . The radiation in total is 5430 ~ 6670 MJ/㎡ ,

the annual total radiant illumination is 10%-15% higher than same-attitude areas in China and 15%-25% higher than lower-middle reaches of the Yangtze River. Secondly, the days of sunshine are more than six hours, and reach 250~325days[8 ; the

total number of days with temperatures higher than 10℃ are almost more than 150[8 days.

(28)

5.1.1 Plan for Solar‐energy Use 

Since Xinjiang is rich in sunshine resource the use of solar energy such as, solar water heaters, solar building (use of solar energy to the building heating, air conditioning, hot water, electricity), solar thermal power generation technology, solar energy smelting, solar drying, solar greenhouses are some interesting application area. The

government has made series of plans for solar energy. The following is the situation of solar use in Xinjiang.

(1) The promotion of photovoltaic power systems use. This system mainly uses photovoltaic cells and is used in communications systems and remote counties, villages, and other remote islands without electricity. The use of solar photovoltaic began in the 1970s, and rapidly developed in the 1980s. So far, the installed capacity of solar photovoltaic is rising. In Xinjiang, some large scale and small scale Photovoltaic power stations are being built. [23 ]

(2) Solar heating. Use the local rich solar resource to provide the energy for local people’s life. It can solve the problem of heating in winter and improve the living conditions of local people; moreover, it promotes local economic prosperity and social stability also the ecological environment. In addition, it saves much energy and fuel cost of the nation. [23 ]

~ 28 ~ 

(29)

solar biogas fermentation technology is a pollution-free treatment of cattle’s excretion and reduces the density of mosquito and pests and the spread of various diseases and morbidity. Finally, in the area of ecology, it replaces the traditional energy and changes the rural area’s energy structure. It reduces the use of wood fuel and thereby protects forest and prevents water loss, soil erosion and water pollution. [23 ]

From this table, we can see that solar energy not only saves money, but also saves energy and it is a clear energy and does not pollute the environment.

5.1.3 Problems 

There are some problems in the development of solar-energy use in Xinjiang.

~ 29 ~ 

(30)

● Few people grasp the photovoltaic technology

● Photovoltaic products’ system and manufacture are hampered, and the creativity is also poor.

● Photovoltaic power generation products have no technical standards.

● There are lot of raw materials, components that depend on imports and mainland, so the cost of production equipment is high.

(2) Some problems of solar heat use.

● The ability of research is weak and there is a lack of professional technology teams.

● Xinjiang has not set up the supervision of product quality and detection system yet.

5.2 Biomass Energy in Xinjiang 

Biomass means "natural material." When biomass is burned, it releases heat – just like the wood logs in the campfire. [17]

Biomass energy uses natural materials like trees and plants to make electricity. It can also mean waste products like trash. [17]

Biomass is the second common form of renewable energy in the United States, providing enough electricity to power more than two million homes. [17]

(31)

5.2.1 Plan for biomass Use   

Stalk is a green renewable energy. Xinjiang has largest-proportion of cotton production in the whole country of China. Therefore the stalks of cotton are richest there. Stalk is one kind of biomass energy and people use stalk for burning, even for generating electricity. So it is called green electricity.

Figure 7 stalk

Xinjiang has setup a power plant which uses the stalk to burn in 2008. The generated electrical energy will reach 150,000,000[1 kWh.This

project promotes environmental protection and develops Xinjiang’s economy.

Problem 1. High cost

2. Immature technology

5.3 Natural Gas in Xinjiang 

Natural Gas is a vital component of the world's energy supply. It is one of the cleanest, safest, and most useful energy in all the energy sources.

There are some advantages of natural gas: ● Environment will be clean

● It is economical and efficient

‘West-East natural gas transmission’ project

West China is rich in natural gas, but the people in the west of China use the natural gas rarely in their life and the industry there is not developed. On the other hand, in the east of the China there is a shortage of natural gas and the people there have high demand for natural gas and the industries are very developed. Therefore, the government drafts the policy “West-East Natural Gas Transmission Project”. This project not only promotes the economy of Xinjiang, but also makes the best use of national resources.

6. Municipal Waste 

With China’s urban development, the amount of city waste will rapidly increase. Hence, waste has become the focus of the current environmental issues.

1 Treatmen

6.1.1 Landfill 

The amount of waste is rapidly increasing and there is a lack of place to landfill, but landfill is the main way of waste treatment in Xinjiang. The garbage emission in Xinjiang is about 1700 tons[1 everyday, but

the capacity of landfill is just about 400 tons[1 .

0] 0]

 

6.1.2 Incineration 

Beside landfill, incineration is another way of waste treatment. According to information available, in 2002 Xinjiang had waster of about 3200 tons per day but the capacity of incineration wastes was just about 600 tons per day .

[11]

[11]

On the other hand, China has a plan to use the waste incineration for generation electricity in the future. This project, not only saves the land resource and reduces the environment pollution, but also uses the resource rational and change the traditional way of waste treatment.

6.2 Problems 

(1) There is low effect of landfill treatment and secondary pollution is evident. At first, the process of landfill could make many kinds of harmful gases, and pollute the air and people’s health. Secondly, it seriously pollutes the surrounding environment and underground water sources. Finally, it occupies great amount land resource.

(3) Many garbage plants still have some safety problems. For instance, some discarded chemicals or inflammable liquids will cause explosion

 

6.3 Suggestions 

 

(1) Reinforce supervision to manage the garbage plants.

(2) Reinforce the technical expert’s training to improve the business management level and ensure the healthy development of efficient safety; moreover, to ensure that municipal waste really achieve safe disposal standards.

(3)Introduce advanced technologies and methods from other developed countries, to reduce the environment pollution and improve the municipal waste treatment system.

7. Conclusion and discussion 

From the analysis above, we can see that Xinjiang is a province with rich resources and great potential for development. At present, coal, natural gas, oil, solar and wind power are important recourses, and they play a positive role for Xinjiang’s economy and society development.

Firstly, coal is an important energy resource in Xinjiang. And as an important energy, the development of coal in Xinjiang also influences Xinjiang’s economy development.

Secondly, Wind power is also developed. In Xinjiang the wind power is abundant, and wind energy is a renewable energy. Dabancheng wind power station is one of the biggest wind powers in China. Accordingly, it brings high economy benefits to China.

Finally, According to the tables, we can find that energy consumption in industry is the biggest part which is more than the total consumption of the other sectors in Xinjiang. It means that industry take such important role in the economy. Since the energy use in Xinjiang develops at a high speed, problems related with energy use and energy efficiency and many other questions needs to be resolved. So here are some suggestions to resolve the problems in the development of energy use in Xinjiang

(1) Strengthening the environment protection

pollution, and the green house effect. Using the cleaning energy, limiting the amount of emission, recycling materials which can be recycled are some good choices to protect the environment. (2) Using the new technologies

Xinjiang still uses the traditional technologies in some process of energy production. The technologies cause a big amount of waste of energy. Hence, new technologies should be used to save energy and to promote the efficiency of energy utilization. (3) Developing more source of energy

There different types of energy resources in Xinjiang, for example, wind power, natural gas, oil, solar energy. But Xinjiang also need to develop other energy sources, such as, bio-fuel, geothermal and nuclear energy.

(4) Strengthening the cooperation and communication with other provinces and other developed countries. Some developed countries have many developed methods and advanced technologies.

(5) Reduce the total consumption of energy
