Abstract

The aim of this paper is to identify the correlations between energy consumption and the factors that control usage in the city of Tangshan. To do this, we first analyze the current status of Tangshan’s economic development and energy consumption, and then applied the logarithmic mean Divisia index to identify the factors affecting the changes in energy consumption of all sectors. The findings are summarized as follows: (1) secondary industry accounts for an extremely high percentage of industry in Tangshan city, much higher than the national average; from 2007 to 2012, the proportion of secondary industry increased in Tangshan city; (2) Tangshan’s energy consumption in 2013 was nearly twice that in 2005. Coal and coke coal consumption was responsible for 96.2% of total energy consumption in 2005 and 95.1% in 2013; (3) Tangshan’s energy intensity decreased from 3.00 tce/thousand Yuan in 2005 to 1.85 tce/thousand Yuan in 2013. However, the energy intensity of Tangshan was far more than the average for China, and the decline in Tangshan’s energy intensity was much slower than the average for China; (4) The technical effect plays a dominant role in decreasing energy consumption in most sectors, and the scale effect is the most important contributor to increasing energy consumption in all sectors. Input structural and final use structural effects play different roles in energy consumption in different sectors.

In order to identify the factors contributing to changes in energy consumption in the city of Tangshan, we first analyzed current economic development and industrial structure within this region and considered energy consumption

Summary

Introduction

Global warming negatively affects the sustainable development of both ecosystems and the global environment. In the 21st Conference of Parties to the United Nations Framework Convention on Climate Change, the Chinese government further committed to reduce carbon dioxide emissions per unit GDP by 60%–65% compared to the 2005 level, with the peak carbon dioxide emission being reached by 2030. China distributed the emission reductions to local governments during the 12th Five-Year Plans and will continue this policy during the 13th Five-Year Plans [1,2]. In this context, an in-depth study of the trends in urban energy consumption and influencing factors will help achieve the overall goals of saving energy and reducing emissions
