“…It provides a comparison of different energies based on full life cycle assessments which have been performed in the last 10 to 15 years [11]. More recent work in this area includes the studies of Cui L. et al [12] and Wang N. et al [13], but here one can also note that the phase of extraction of fossil fuels is just one of many individual processes under consideration which contribute to a blurring of the results which are significant for the mining industry when compared to other environmental burdens of coal power generation. There are far fewer publications focusing solely on the mining phase and analysing the specific conditions of extraction and its related environmental impact.…”

This paper presents a model combining the LCA (Life Cycle Assessment) of fossil fuel extraction with its quality parameters and related CO2, SO2 and dust emissions at the stage of the combustion process. The model which was developed aims to identify the environmental impact of the processes of electricity production from selected energy carriers over their whole life cycle. The model takes into account the full LCA of fossil fuel extraction (of both hard and brown coal), its enrichment and fuel production as well as the environmental impact associated with emissions introduced into the air at the stage of electricity generation based on the fuels evaluated. Such an approach allows one to determine the fuel quality parameters that affect the environmental impact of energy production based on an LCA of mining and assigns the degree of environmental impact involved in particular production processes. Overall, the results obtained based on the proposed model permit the identification and prioritisation of the individual processes in the electricity generation life cycle which contribute the highest share in the general environmental impact indicator, having taken into account the modelling of the quality of the fuels used (calorific value, ash and sulphur content).

The European Union has set targets to reduce greenhouse gas emissions in total energy consumption, ensure the development and use of clean energy sources, and strive to reduce carbon emissions by 90% from 1990 levels by 2050. This study attempts to assess the environmental impact of electricity production on electricity demand and associated emissions in Italy through a three-step process. First, a literature review was conducted to estimate the growth of electricity demand in Italy by population and industry in 2014. Secondly, the CO2 and SO2 produced in the process of power generation by different power production methods were evaluated and compared. Finally, according to the current production and power models, the development trend of renewable energy in Italy in 2050 was estimated, and the satisfactory conclusion is that the renewable energy can fully meet the supply and demand in 2050 in Italy.

“…The policy measures mainly include the elimination of backward units, project approval standards, power generation price supervision, tax incentives, loan policies, and information disclosure. The paper [18] combines life cycle assessment and life cycle cost calculation methods to analyze and compare the environmental and economic impacts of 315 MW units before and after the ultra-clean emission transformation. After the ultra-clean emission transformation, the environmental impact of 1000 kWh power plant flue gas treatment has been reduced from 0.1529 to 0.1295.…”

In China's energy consumption, about 50% of coal is used for power generation conversion, and the resulting environmental impact and air pollution problems cannot be ignored. Therefore, it is of great practical significance to improve the level of clean coal utilization. Based on the background that the country currently grants a subsidy of RMB 0.01/kWh for the "near-zero emission" of thermal power, this paper applies system dynamics (SD) modeling to simulate the impact of different policy scenarios on the promotion and effects of "near-zero emission" of thermal power. From the perspective of promotion speed and emission reduction contribution, simulation analysis found that thermal power "near-zero emission" technology can bring more significant environmental benefits and has promotion value. The main conclusions are as follows: (1) After 2020, if the current subsidy of RMB 0.01/kWh continues to be implemented, the "near-zero emission" retrofit of stock units can be fully completed in early 2026. (2) Compared with no policy subsidies, the cumulative emission reduction of sulfur dioxide, nitrogen oxides and soot will be approximately 15.13 million tons, 15.13 million tons and 2.37 million tons from the beginning of 2016 to the beginning of 2026, respectively.
