“…Consequently, coal-fired electricity production accounts for a major share of the global energy mix (BP 2018), particularly in industrialised nations such as Germany, Russia, Poland, UK, China and Australia (Wierzbowski et al 2017;Oberschelp et al 2019). Over the years, the growing demand for a cheap and reliable supply of electricity has also stimulated significant investments in coal-fired power in developing countries such as India, China, and South Africa (Hancox 2016;Tang et al 2018). The highlighted studies submit that coal consumption plays a strategic role in various sectors largely due to the nexus of energy demand and economic growth.…”

In this study, the physicochemical, microstructural, mineralogical, thermal, and kinetic properties of three (3) newly discovered coals from Akunza (AKZ), Ome (OME), and Shiga (SHG) in Nigeria were examined for potential energy recovery. Physicochemical analysis revealed high combustible but low levels of polluting elements. The higher heating values (HHV) ranged from 18.65 MJ/kg (AKZ) to 26.59 MJ/kg (SHG). Microstructure and mineralogical analyses revealed particles with a rough texture, surfaces, and glassy lustre, which could be ascribed to metals, quartz, and kaolinite minerals. The major elements (C, O, Si, and Al), along with minor elements (Ca, Cu, Fe, K, Mg, S, and Ti) detected are associated with clays, salts, or the porphyrin constituents of coal. Thermal analysis showed mass loss (M L ) ranges from 30.51% – 87.57% and residual mass (R M ) from 12.44% – 69.49% under combustion (oxidative) and pyrolysis (non-oxidative) TGA conditions due to thermal degradation of organic matter, vitrinite, inertinite and liptinite macerals. Kinetic analysis revealed that the coal samples are highly reactive under the non-isothermal oxidative and non-oxidative conditions based on the Coats-Redfern Model. The activation energy ( E a ) ranged from 23.81 kJ/mol – 89.56 kJ/mol whereas the pre-exponential factor ( k o ) ranged from 6.77×10 -04 min -1 – 1.72×10 03 min -1 under pyrolysis and combustion conditions. In conclusion, the coals are practical feedstocks for either industrial applications or energy recovery.

“…Typical studies are combined with the structural deconstruction analysis method. Liu et al (2018) [76] analyzed the reasons for the change of coal consumption in China based on embodied energy measurement. Their results indicated that coal consumption variations during 1997-2014 in China can be divided into four phases, and their reasons can be explained by four factors, including economic scale effect, industrial structure effect, energy intensity effect, and energy mix effect.…”

Embodied energy is termed as the total (direct and indirect) energy required to produce economic or environmental goods and services. It is different from the direct energy measurement of energy consumption. Due to the importance of energy security, it has attracted increasing attention. In order to explore whether and to what extent embodied energy can provide a more innovative approach and competitive perspective to energy security issues, 2608 relevant pieces of literature from the Web of Science core collection are analyzed in this study. Results show that embodied energy has been taken seriously. Moreover, by reviewing the typical literature, this paper first summarizes the embodied energy calculation methods and models, then investigates how embodied energy provides a new perspective to energy issues, and lastly analyzes how to show value in energy security issues in its application of guiding policy-making and energy security studies. In summary, there is no doubt that embodied energy can provide a more integrated perspective on energy consumption and demand and provide a more scientific reference for policy-making to enhance energy security. However, because of data and application scope limitations, establishing a comprehensive energy security research and application system with embodied energy measurements needs hard work.

“…Only two events have been identified to have caused changes in China's carbon emission pathways, namely the reform and opening up of 1978 and China's accession to the World Trade Organization(WTO) in 2001 [19,21]. In the research on China's emission pathways after 2001, either no phases have been defined or the phases have been defined according to China's five-year plan periods [22,28,34,36]. That means connections between the carbon emission pathway and economic development have not been effectively established.…”

The Periodic Characteristics of China’s Economic Carbon Intensity Change and the Impacts of Economic Transformation

Understanding the pathway of carbon emissions is an important basis for establishing a national climate strategy. In this paper, the change in China's economic carbon intensity since its accession to the World Trade Organization has been analyzed with a time series decomposition analysis method. Four phases with distinctive features are defined, and the significant fluctuations in China's economic carbon intensity after 2001 are explained in detail. From the phase-average perspective, the contributions of major factors to the economic carbon intensity change have evolved steadily, instead of through highly volatile change on a yearly basis, and the gradual changes have been caused mainly by the development of the industrial sectors. Induced by the new normal in economic development, the change of China's economic carbon intensity has entered a new phase driven by multiple factors with economic structural improvement being the most important contributor, as well as the continuingly, though decreasingly, important factor of energy efficiency.
