Adoption of the electric car to mitigate air pollution and climate change: myth or reality? This study aims to bring out the energy and climate mitigation impacts of mass introduction of electric cars in city of Sao Paulo, Brazil. A working scenario of 10 percent penetration of electric cars replacing gasoline-powered vehicles by 2020 and 20 percent by 2030 was set. The impact on the energy mix and...
With the change of global and the development of economy, low-carbon economy is attracting high attention of society and academe. Through the analysis of the relationship between low-carbon economy and economic development, the author proposes that the essence of low-carbon economy is the transformation of regional socio-economic. On this basis, the article takes Jinhua for example. The first is to...
On Dec. 2009, the Chinese government set up a low-carbon target of a 40%~ 45% carbon emission reductions per unit of GDP by 2020 compared to the 2005 level. To contribute to these discussions, we developed a carbon emission supervision system for the low-carbon city construction. The concept, role, contents and construction methods of carbon emission supervision system for have been proposed. The...
This paper describes a design and detailed analysis of a grid connected solar PV system for the Ahsanullah University of Science and Technology (AUST) campus. Various design considerations are discussed including the factors and parameters with limited data and information resources available for Bangladesh. Cost analysis reveals that the proposed design is economical and cost effective for the AUST...
In response to increasing environmental problems and consciousness in relation to urbanization, more and more cities are trying to become eco-cities. We can question, however, whether these cities can be considered as sustainable cities. The eco-city concept usually includes criteria regarding energy and water consumption, transport, waste management, amount of green spaces, etc. However, food consumed...
Firstly, this paper analyzes the status of energy consumption in Henan Province, and then the improved GM (1, 1) model is used to predict the energy consumption and energy structure in the following several years; it shows that the energy structure is unreasonable in the coming years; coal is consumed too much and the ratio of natural gas, renewable energy and new energy should be increased. Finally,...
The article builds the coordinating degree evaluation index system of energy-economy-environment (3E) composed of three modules, five factors and 34 indexes based on research on energy, economic and environmental correlation in the process of economic development, and uses expert evaluation method to determine the weight of each index; finally, we use AHP-GRAM to evaluate and analyze the 3E system...
To enlarge the difference of assessment values for energy consumption in equipment manufacturing industry among varied time, AIA based time series scatter degree method (AIA/TSSDM) is proposed so as to improve the energy consumption assessment performance. The comprehensive solution for energy consumption assessment by AIA/TSSDM is presented. AIA is introduced to adapt the conventional scatter degree...
This paper integrates the evaluation index system of sustainable development at home and abroad and calculates the technical efficiency, pure technical efficiency and scale efficiency of the sustainable development ability of energy consumption of 30 provinces (autonomous regions) in China in 2007 with CCR, BCC, SBM, and Super-SBM models. The results show that the ability of most provinces in energy...
The scientific and reasonable measure of energy-saving potential is the foundation based on which government departments at all levels sets their energy-saving goals and make corresponding policies. With reference to the research results of other scholars, the paper gives a new definition of the energy-saving potential. The definition is expected to cancel the incomparability of industrial structures,...
