Based On The Research On Energy Efficiency Perspective Of Carbon Emissions

Both the tight energy efficiency problems and the huge pressure of carbon-dioxide emission reduction from the world are challenging China’s developmenttoday and future. What can we do to achieve better economic growth meanwhile withmeeting the constraint of carbon-dioxide emission reduction? It is now becoming oneof the most urgent problems for our sustainable development. In order to solve the bigproblem, this paper does a theoretical and empirical study on china’s energyefficiency and carbon-dioxide emission, especially on those of industry sector. By theSFA model and method which is often used in efficiency studies, this paper sets up aSFA model for energy efficiency and carbon-dioxide emissions, measuring thedifference between the real and the frontier of the carbon-dioxide emissions fromindustry sector. By situations analyzing of carbon-dioxide emissions with the energystructure factor entered, it discusses the solutions to deal with energy saving andcarbon-dioxide emissions reduction, hoping to help China’s sustainable development.This paper including seven parts: part one, introduction; part two, reviewing thethe literature studies on energy and carbon-dioxide emissions; part three, theoreticalstudying on china’s energy efficiency and carbon-dioxide emissions. Part four,comparatively analyzing China’s carbon-dioxide emissions and energy efficiencywith other countries; Part five, by the carbon-dioxide emissions frontiers model,empirically studying the energy efficiency and carbon-dioxide emissions of in China’sindustry sector, and discussing the gap between the real and the technical frontier.Part six, situations analysis of industrial energy efficiency and carbon-dioxideemissions in China. Finally, it gives conclusions and suggestions for helping energysaving and carbon-dioxide emissions reduction.It proposes the following main viewpoints:1, China’s total carbon-dioxide emission is huge. Although it is true that thecarbon-dioxide emission intensity has dropped obviously in recent years, the wholesituation of China’s carbon-dioxide emissions is very hard because of the presentrapid growth of the total carbon emissions and per capita carbon emissions.2, Industry sector is the main energy consuming sector and the main carbon-dioxide emission sector in China. There has great improvement on energy efficiencyin China industry sector in recent years, but there still exists obvious gaps especiallycomparing China with other countries and the average situation of the world. It is veryimportant and urgent for China’s industry sector to further improving its energyefficiency and decreasing its energy intensity and carbon intensity.3,If analyzing the energy using in detail industry sectors, we can infers that the manufacturing sector and the mining and quarrying sector are the better energy usingsectors comparing with other industry sectors. Based on the data analysis, it arguesthat the former two sectors has greatly improved their energy efficiency withdecreasing energy intensity, while other sectors, such as the production anddistribution of electric power and heat power sector, has not good energy efficiencyconditions.4, By the frontier studies and measurement, it proposes that:(1) there existscertain gaps between the industry practice carbon-dioxide emissions and the technicalfrontier.(2) under the present industry production input and output set, it is difficult tosave more energy and decrease any more carbon-dioxide emissions.(3) maybe we cando much more improvement on energy saving and carbon-dioxide emissions when putthe energy saving and carbon-dioxide emissions into the carbon-emissions technicalconditions.(4) with empirically studying, it finds that the fluctuation of industryenergy efficiency influences its carbon-dioxide emissions. Changeable energyefficiency means the energy input-output production is not stable, thus if we want tosuccessfully carry out the carbon-dioxide emissions task, we must manage and controlthe energy efficiency to a stable and better condition.5, with situations analysis this paper proposes that to complete the task of energysaving and carbon-dioxide emission reduction, we can adjust the energy structure andimprove energy using technology.(1) Energy structure adjusting, especially for thefossil energy, will bring obvious different carbon-dioxide emissions. It is a necessarychose for China to decrease the coal proposition in energy consuming in industrysectors.(2)Under the constraint of present energy consume structure, maybe it isdifficult to change the coal as the primary energy in China Industry’s production,encouraging technical innovation on energy using, for example innovation on coallow-carbon-using, can be taken into consideration to reduce carbon emissions inChina industry.(3) This paper finds that using different energy carbon coefficientswe can have different findings. When changing the coefficients especially thecoefficients of electric, the carbon-dioxide emission is varied obviously. Based thisfinding, this paper argues that we can use nuclear power, wind power, heat power, etc,to substitute traditional power to reduce carbon-dioxide emissions.6, The carbon-dioxide emissions of electric power and other energies which areinput in industry production should also be taken into consideration of energy savingand carbon emission reduction program. For the sake of using coal input to electricoutput in present electric power production, the carbon emissions during the processof power production is also very huge, while often neglected. In order to achievefinally success of energy saving and carbon-dioxide emissions reduction, Chinashould pay more attention to electric power besides the fossil energy use.
