The Chinese government is going to “push ahead the revolution of energy production and consumption, and establish a clean, low-carbon, secure, and efficient energy system”, which points out a direction for the energy industry in the new era. Using the analytic hierarchy process of the system analysis method, we constructed an indicator system of the modern Chinese energy system, and by determining the weighting of each indicator, we obtained the composite index of the modern Chinese energy system, as well as four sub-indexes of clean, low-carbon, secure, and efficient. Then, we investigated policy changes and energy development characteristics of important periods, and performed historical trend analysis. Finally, we forecasted the composite index and four sub-indexes by 2050, and proposed an energy development path and policy suggestions to achieve a modern Chinese energy system as soon as possible.

The ambition to keep global warming well below 2 °C above pre-industrial levels, as recognised in the Paris Agreement, implies a reorientation towards low-carbon societal development and, ultimately, the decarbonisation of human societies and economies. While climate policy has been geared towards achieving set emission reduction targets, the decarbonisation of key socioeconomic sectors such as energy-intensive natural resource-based industries (ENRIs) has not yet been sufficiently addressed, neither politically nor in science. Decarbonising the ENRIs is a complex societal problem that will require structural transformation technologically as well as socially. Understanding the conditions for transformative change therefore necessitates integrated knowledge from multiple perspectives of different research fields. In this paper, we examine the potential of combining three different research fields and critically scrutinize the challenges to integration for understanding the conditions for industrial decarbonisation: energy system analysis, sustainability transition research and policy studies. We argue that these perspectives are complementary—a fundamental condition for fruitful integration—but not easily compatible since they are sometimes based on different ontological assumptions. The research fields are in themselves heterogeneous, which poses additional challenges to an integrated research approach. Drawing on experiences from a Swedish research project (GIST2050) on industrial decarbonisation, we suggest a modest approach to integrated research that could progressively develop from multidisciplinary exchange towards more integrated forms of interdisciplinarity by means of cross-disciplinary dialogue and understanding.

The Chinese government has planned to reduce domestic energy consumption by 20% by 2010. In order to analysis the energy saving potential in the city’s energy system from different aspects, an energy consumption model of China energy system was provided based on bottom-up MARKAL model, which assessed the future competitiveness of different types of energy supplications and the future growth in energy service demand in China under different scenarios and conditions. The modeled results were also analyzed and discussed. The model established the foundation for the study of energy technology development and energy policy in the future.

Energy systems in cities need to be decarbonized and are becoming more integrated via energy sector coupling. Today, cities often use simple methods to assess their low carbon targets, e.g., carbon calculators, and these methods use annualized carbon reduction potentials. For example, reductions from heat savings in buildings or fuel demand in transport. This is done because it is simple and fast. This paper describes a methodology that goes beyond carbon calculators and assesses highly renewable energy systems. The methodology is carried out for a case city—Sønderborg, Denmark. Using a national 100% renewable energy study and a suitable energy system analysis tool (EnergyPLAN), the method accounts for inter-sector coupling and energy system dynamics. The energy system is assessed by comparing the results from the analysis tool against numerous key sustainability factors for a Smart Energy System. The paper illustrates how the method delivers a sustainable 100% renewable Smart Energy System for Sønderborg, which can be part of the Danish energy system in 2050 based on local resources. The paper discusses the broader applicability of the method within strategic energy planning.

Carbon Prices

The world’s energy system is undergoing an evolution from high-carbon to low-carbon. The Chinese government has also proposed the carbon neutral plan. Foreign practical experience shows that there is an interaction between the carbon market and the electricity market, therefore, understanding the relationship between the two markets is essential to ensure the efficient operation of both markets. In the context of China's power market reform, this paper studies the impact of introducing carbon prices into the wholesale market, and conducts a case study based on the data of a certain area in GD province. The results show that after the carbon price is transmitted to the electricity price, the more low-carbon and environmentally friendly power generation technologies will gain greater advantages in the electricity market, which is conducive to the clean energy transformation of the power system. Finally, this paper puts forward feasible suggestions for the reform of the electricity market under China’s carbon emission reduction target.

Low Carbon Development

Due to the severe situation of global climate change and depletion of energy resources, low-carbon development has become an inevitable choice for global climate change and maintaining sustainable economic and social development. In order to promote low-carbon development, we should scientifically evaluate the low-carbon development status of a country, economy or region. At present, the research on low-carbon evaluation indicators is still in the exploratory stage. There are not many low-carbon indicators that are really used in practice, and there is currently no recognized and authoritative low-carbon evaluation indicator system. Based on this, this article attempts to use the analytic hierarchy process to further study the low-carbon development indicator system, to establish a scientific and objective system of low-carbon development indicators, and use such an indicator system to guide and promote low-carbon development.

Low Carbon Technologies

To overcome the negative environemental impact of the actual power system, an optimal description of quasi-static electromagnetics relying on a reversible interpretation of the Faraday’s law is given. Due to the overabundance of carbon-free energy sources, this description makes it possible to consider an evolution towards an energy system favoring low-carbon technologies. The management for changing is then explored through a simplified linear-programming problem and an analogy with phase transitions in physics is drawn.
