Primary energy-related carbon dioxide emissions in China

Climate change is one of the focuses to mitigate greenhouse effect and reduce carbon dioxide emissions.First,the paper summarizes on the carbon dioxide emission factors and methods suitable to the situation in China.Second,it analyzes the primary energy-related carbon dioxide emissions during the period between 1995 and 2005 from different fossil fuels and different zones.The trend of primary energy-related carbon dioxide emissions from 1995 to 2005 is"first decreasing and later increasing."Seven regions-Liaoning,Shanxi,Hebei,Shandong,Henan,and Jiangsu-and most of the provinces(cities or regions)were found to have similar trends regarding total carbon dioxide emissions in China.The annual carbon dioxide emissions and the growth ratio of these seven regions are much higher compared to those of the other 24 provinces(cities or regions).Finally,this paper puts forward some suggestions to reduce carbon dioxide.     

Pollutant emissions,energy consumption and economic development in China:Evidence from dynamic panel data

This study investigates the relationship among pollutant emissions,energy consumption and economic development in China during the period 1982-2007 by using a one-step GMM-system model under a multivariable panel VAR framework,controlling for capital stock and labor force.Regarding the data for all 28 provinces as a whole,we find that there is a unidirectional positive relationship running from pollutant emission to economic development and a unidirectional negative relationship between pollutant emission and energy consumption.Based on traditional economic planning,the panel data of28 provinces are divided into two cross-province groups.It is discovered that in the eastern coastal region of China,there is only a unidirectional positive causal relationship leading from economic development to pollutant emission;while in the central and western regions,there are the unidirectional Granger causal relationships between pollutant emission and energy consumption,as well as between pollutant emission and economic development.There is also a unique unidirectional causal relationship running from economic development to energy consumption,which does not appear in the eastem coastal region or in China as a whole.     

Technological Progress,Structural Change and China’s Energy Efficiency

Abstract

China has witnessed rapid economic development since 1978, and during the time, energy production and consumption developed at a tremendous speed as well. Energy efficiency which can be measured by energy consumption per unit of GDP, however, experienced continuous decrease. Theoretically, the change of energy efficiency can be attributed to industry structural change and technological change. In order to explain the transformation of Chinese energy efficiency, we adopt logarithmic mean Divisia index techniques to decompose changes in energy intensity in the period of 1994–2005. We find that technological change is the dominant contributor in the decline of energy intensity, but the contribution has declined since 2001. The change in industry structure has decreased the energy intensity before 1998, but raised the intensity after 1998. Decomposed technological effects for all sectors indicate that technological progresses in high energy consuming industries such as raw chemical materials and chemical products, smelting and pressing of ferrous metals, manufacture of non-metallic mineral products and household contribute are the principal drivers of China’s declining energy intensity.     

China’s Export Expansion,Export Structure and Energy Consumption

Abstract

Since the reform and opening up, China’s export trade has maintained a rapid growth; meanwhile, China’s energy consumption has been increasing sharply. “High export and high energy consumption” has become the feature of China’s trade and economic development. In this paper, based on the input–output analysis approach, the authors have conducted an empirical study on the export trade and energy consumption of 21 trade industrial sectors. The results show that, China is a big net exporter of embodied energy. Assuming that the export growth rate of embodied energy maintains to be about 23.6%, the average annual growth rate of the past 32 years, and based on the input–output data of 2005, by 2030 China’s net export of embodied energy would be over eight times more than the aggregate energy production, which is obviously infeasible. As a country of very low per capita energy, China must change its export pattern, encourage or restrain the export of different industrial sectors according to their energy consumption intensity, and promote structural change of energy– efficient exported products, so as to achieve the sustainable development. Accordingly, the authors put forward some suggestions.     

Recycling and Reusing Heat Energy During the Production of Powdery Phospholipid

The temperature is 56.5°C when acetone gas is rectified during the production of powdery phospholipid. If heat exchanger is added, heat energy that is reclaimed can be used by other heaters. On the basis of exchange hot water (51°C) 4m³ every minute, a factory with the productivity of powdery phospholipid being 10 ton a day can save 533.2 ton standard coal which is equivalent to 746.48 ton common coal. If this technique of saving energy and reducing emission could be widely used in correlative industries of all over the country, economic benefits will be prominent.     

Analysis of the Energy Embodied in Foreign Goods Trade of China

Abstract

In recent years, scientists have been increasingly interested in the energy embodied in traded goods among countries. In this article, the direct energy intensities in various economic sectors of China were calculated with the data of energy consumption and output value of each sector, and the input–output table was used to estimate the external energy consumption. The total energy intensity of all sectors was then obtained. From the data of international trade, the energy embodied in goods trade of China was estimated for the period of 1994–2001. During this period, the average energy intensity of imported goods was always higher than that of exported ones. As a country with a surplus in international goods trade, China actually imported net embodied energy in the past few years. The net embodied energy imported was at the same magnitude of the imported energy in the form of fossil fuels.     

Policy options to promote Chinese new energy vehicles consumption

Inspired by the green revolution, new energy vehicles (NEVs) provide a fresh, alternative mode of transportation for Chinese consumers that reduce their reliance on traditional, gasoline/diesel-based cars. However, despite strong government support for NEVs in China, the level of uptake by consumers remains slow. Using Shanghai as a case study, this article provides a much-needed insight into local consumers’ motivations to invest in NEVs through a survey of 100 Shanghai residents. Results indicate that current NEV promotion policies do not have a significant impact on the cognitive trade-off of NEV consumption under the “Integrated Consumer Behavior Model,” mainly due to inconvenient charging facilities, technical concerns regarding battery, higher prices, and wait-and-see attitudes regarding the pilot policy environment. Drawing on experiences from Sweden and New Zealand, this research serves to enhance knowledge on consumer attitudes towards NEVs and assist policy makers in developing more effective green consumption promotion campaigns in the future.     

Gatekeeping and Communities in Energy Transition: A Study of the Block Island Wind Farm

ABSTRACT

The Block Island Wind Farm (BIWF) is the first offshore wind farm in the United States. Using gatekeeping theory as a framework, this research analyzes local and regional/national newspaper coverage of the BIWF paying particular attention to the use of sources. The data suggest that the differences between newspaper source usage from 1 January 2008 to 1 July 2017 is minimal. However, business sources appeared more than any other group, including government sources, which is a new finding. The prevalence of business sources leads to important questions about the role of businesses in shaping narratives about community transitions to renewable energy systems.     

Spreading the News on Carbon Capture and Storage: A State-Level Comparison of US Media

Carbon capture and storage (CCS) has received abundant federal support in the USA as an energy technology to mitigate climate change, yet its position within the energy system remains uncertain. Because media play a significant role in shaping public conversations about science and technology, we analyzed media portrayal of CCS in newspapers from four strategically selected states. We grounded the analysis in Luhmann's theory of social functions, operationalized through the socio-political evaluation of energy deployment (SPEED) framework. Coverage emphasized economic, political/legal, and technical functions and focused on benefits, rather than risks of adoption. Although news coverage connected CCS with climate change, the connection was constrained by political/legal functions. Media responses to this constraint indicate how communication across multiple social functions may influence deployment of energy technologies.     

Rearticulating Nuclear Power: Energy Activism and Contested Common Sense

This essay utilizes the perspective of articulation theory to examine how environmental advocates, public interest organizations, and citizen-consumers have challenged the nuclear industry's expansion efforts, linking strategies at local and global levels. The industry has articulated a material and discursive formation including reactor construction projects, financial and political arrangements, and an overarching narrative of nuclear necessity and inevitability. Opponents have responded by linking organizations, individuals, histories, geographies, and expertise, re-articulating the place of nuclear power in the field of energy choices. This essay examines those opposing articulations in the context of efforts to construct new nuclear power plants in the southeastern USA. There, opponents have challenged state-level regulatory approval of a corporate merger that would facilitate new nuclear construction and financing arrangements that would shift economic risks from the corporation to consumers. These local engagements have broader consequences: in challenging one corporation's nuclear ambitions, opponents also challenge the global industry narrative of nuclear necessity and inevitability.
