Renewable and non-renewable energy

With the rapid development of its national economy, China has become a major producer and consumer of energy. To guarantee the sustainable development of power industry and national economy, China should exploit fossil and renewable energy efficiently according to the development situation of generation resources. Firstly, this paper analyzes the utilization status of main generation resources in China, such as coal, hydropower and wind energy.

For example, the resource distribution is inconsistent with electricity demand, the renewable energy power output is intermittent, and there is some disruption in coal mining. Finally, combined with the utilization status and issues, this paper presents some improvement approaches from the perspectives of cost, efficiency and external influence. Generation resources refer to the resources used for power generation, which include fossil energy and non-fossil energy resources in China.

Among them, fossil energy resources mainly include coal and natural gas, while non-fossil energy sources consist mainly of nuclear power, hydropower, wind power, and solar power. In recent years, the energy demand has been increasing significantly. Power energy will play an important role in energy structure adjustment and sustainable development. With the rapid development of economy, the healthy development of electric power will provide a powerful mechanism for sustainable development [ 1 ].

Although the distribution of productivity and the distribution of energy resources are not matching, China is vigorously promoting the development of ultra-high voltage UHV transmission technology to achieve sustainable development of electric power [ 2 ]. The main strategy for developing generation resources in China is to optimize the coal industry structure and to develop nuclear power, hydropower, wind power and other renewable energy sources vigorously. Emission reductions from the energy sector will be promoted by increasing fossil energy quality and clean energy generation proportion [ 3 ].

At the same time, the Chinese government will strengthen the development of generation resources to coordinate the integration of renewable energy, promote the construction of the smart grid, and develop energy storage technology [ 4 — 6 ].

To reduce carbon emissions, developed countries attach great importance to the utilization of renewable energy. Chinese policy is that by , the coal utilization proportion will be substantially reduced, coal consumption will peak by , and clean coal technology will be well developed. External cost of coal utilization will be consequently reduced, ensuring sustainable growth of the economy [ 7 , 8 ]. In this paper, based on the view of sustainable development, the issues and solutions of generation resource utilization in China are analyzed.

The reformation of power systems in the world has focused on problems of low carbon technologies, environmental protection, clean energy, and green development. To address climate change and emission reduction, new electricity market and power industry reforms are studied, and renewable energy market mechanisms are explored around the world [ 9 ].

At present, the exploitation of hydro-power generation resources in developed countries has already achieved a high level, hence the exploitation of renewable energy is focused on solar energy, wind energy, geothermal and biomass power. However, renewable energy power generation except for hydropower is held back by lack of large investment, high cost and power intermittency, so renewable energy utilization will not be greatly increased before [ 10 ].

In Britain, the government has already established a series of laws and regulations to promote the development of renewable resources, such as the Non Fossil Fuel Convention and Electricity Law. Subsequently, the concept of renewable energy obligation exists in Britain, which provides credits for power companies engaged in renewable energy to realize sustainable development [ 11 ].

India is one of the earliest countries to carry out an electricity market reform. To influence generation resource utilization, electricity transactions are subject to price control of renewable energy generation, and the Renewable Electricity Certificate mechanism is used to improve the business case for renewable energy [ 12 ].

The United States was the major energy consumer in the world, mainly using coal, oil and natural gas. However, the renewable energy proportion of U. In China, coal utilization is dominant in generation resources, which has brought serious environmental pollution.

To guarantee and promote the low-carbon economy, environmental protection and sustainable development, new energy resources should be actively developed and priority given to developing hydropower, wind power and solar energy.

Additionally, the efficient development of nuclear power is also necessary [ 14 ]. For the comprehensive utilization of generation resources, some scholars have conducted in-depth research in China. Litong DONG studied the comprehensive planning of generation resources, energy management, and power generation transaction [ 15 ]. Shuxiang WANG discussed the optimization model and method of comprehensive utilization for generation resources with emission reduction constraints, analyzed from generation side and the demand side, considering the linkage of these two sides [ 16 ].

In addition, Dudu LIU believed the development of smart power technology will be the key trend of the electricity industry, having an important role to promote the rational allocation and improve the utilization rate of generation resources [ 17 ]. Qingyou YAN analyzed a balanced development problem comprising environment, economy, and power by the way of system dynamics, so as to find a method to solve generation resources shortage [ 18 ]. During the 21st century, electricity demand has been growing in China with an unprecedented speed and the scale is continually expanding, so power grid construction has been continuous and will provide a solid foundation for the developing electricity market.

Only a sound power market mechanism can promote the efficient use of electricity [ 19 ]. At present, the energy sources for power generation in China include coal, natural gas, wind, solar, nuclear energy, and biomass energy. By the end of , the total installed capacity of China reached 1. The total installed capacity of hydropower is GW, with a proportion of And the capacity of grid-connected wind power is GW, with an increase of Additionally, the installed capacity of renewable energy accounted for The overall pattern of geographical distribution is that coal resources are abundant in the east and the north of China.

Coal resources are mainly concentrated in the north of China. In , coal reserves of north China accounted for According to our calculation, coal is mainly distributed in Inner Mongolia autonomous region, Xinjiang autonomous region, Shaanxi province, Shanxi province, Ningxia province and Guizhou province, collectively accounting for about On the basis of the fourth coal forecast [ 20 ], Inner Mongolia autonomous region and Xinjiang autonomous region have the largest proven coal reserves, and followed by Shanxi province.

With the decrease of utilization proportion in coal resource, thermal power investment was For the decline of coal price and technical progress, the new installed capacity was The national thermal power installed capacity was GW. The annual coal consumption dropped by 3. The coal inventory of key power plants in China was about Among them, large coal mine would be reached 2. Actually, it has been realized.

In China, demand for natural gas is very strong, especially with increasing control of air pollution, with many regions showing extraordinary growth.

Annual gas consumption is growing faster than production, so gas supply is very tight, and ensuring supply for the peak gas consumption in the winter heating period seems to be difficult [ 22 ].

To ensure the safe use of gas, gas turbine supply is restricted. For the sake of protecting the gas supply, China raised the price of natural gas for non-residents, but the country has not formed a unified mechanism of gas turbine power generation price, and some enterprises continue to experience losses due to generation cost increase and inadequate local subsidies.

In addition to coal and natural gas, there are some power plants using petroleum products. Oil generation has high pollution and is not a sustainable business, so the proportion of installed capacity has decreased greatly during nearly ten years, and was less than 0. China has abundant water resources, with the highest total amount in the world. According to our survey, by the end of July , the generation output of hydropower was Because of the large difference between topography and rainfall in China, the geographical distribution of hydropower is unbalanced, with most distributed in the west of China.

Thus, the runoff distributions of most rivers are uneven throughout a year and seasonal flow becomes disparate, so high-performance regulating reservoirs need to be constructed. Water resources are concentrated in main streams, which is convenient for centralized development. By the end of , the total installed capacity was about GW.

In downstream Jinsha River and upstream Yangtze River, the total installed capacities are Additionally, the installed capacities around Dadu River and upstream Yellow River are larger than 20 GW each, and the installed capacities around Wujiang, Nanpanjiang and Hongshui Rivers are more than 10 GW each [ 23 ].

As one of the renewable energy sources, hydro energy will become a focus in future power construction. The wind power market in China is growing fast and has become the largest one in the world. According to statistics from the World Wind Energy Council, the compound annual growth rate CAGR for global cumulative installed capacity of wind power was The wind resource is mainly concentrated in the northern region, the southeast coastal area, and the nearby islands.

The wind power generation has become a fast growing industry in the background of global energy shortage, serious environmental pollution and the increased demand for renewable energy. In , the total installed capacity of grid connected wind power was GW, an increase of By the end of , the wind power installed capacity was However, the annual wind power equipment utilization hours were h, which dropped by h over the previous year, because the development of the national transmission grid has not kept up with the development of wind power.

This means the annual new installed capacity of wind power in China will be up to 20 GW. According to the planning in the Thirteenth Five-Year Plan, new installed capacity of wind power in China will be up to GW during — Among them, new installed capacity in the northwest and the northeast will be 60 GW.

New installed capacity will be 30 GW in the central east and 10 GW in offshore [ 26 ]. In addition to water and wind resources, there are other renewable energy sources for power generation in China, such as solar energy and biomass energy, but those generation resources have low proportion in China. For example, total installed capacity of solar power accounted for only 2. The utilization proportion of other renewable energy is not high, but renewable energy will be developed continuously in the coming decades.

Based on macroscopic angles, the STEP model presents an analysis framework with respect to political, economic, social, and technological factors. The analysis of the political aspect includes the political system, policy, laws and regulations in relevant countries or regions. The analysis of the economic aspect includes market competition and industry environment according to the domestic economic situation and developmental trend.

The analysis of the social aspect includes societal factors, including cultural traditions, values and social structure. Finally, the technology aspect we will study later includes the social technology level and trend, the influence of technological breakthroughs and technical change.

This paper analyzes the issues of generation resource utilization from these four dimensions as shown in Fig. The uneven distribution of fossil energy results in high transport cost.

The inconsistency of coal production and consumption has been studied by replacing coal demand with power demand, ignoring consumption of coal outside the power sector. A Lorenz curve is fitted according to the cumulative percentage of power consumption and coal production in respective provinces. Consequently, the uneven distribution degrees can be analyzed, as illustrated in Fig. The graph of Gini coefficient is the crooked line in Fig.

A coefficient of 0 expresses perfect equality among provinces, while 1 would mean that production and consumption are completely disparate. From the Fig. However, the practical Lorenz curve is the crooked line in Fig. Therefore, provincial coal production and consumption has an unbalanced distribution in China, hence there is a severe inconsistency in the distribution of coal and the distribution of electricity demand.
