South Africa accounted for more than one-third of the total energy-related CO2 emissions on the African continent. South Africa's energy and electricity supplies are dominated by coal. The country's energy mix is expected to shift considerably towards renewables over the next two decades. This paper examines policy options for promoting such a shift to clean electricity, in order for South Africa...
The power demand of many islands in Southeast Asia is projected to increase rapidly over the next decades. Especially on island systems, where the installation of large-scale fossil-fired power plants is not appropriate, renewable energy sources could contribute to an independent, economic and sustainable power supply. To analyze the cost-effective integration of renewables on large islands, a power...
In the wake of increasing challenges of high prices of oil and gas and uncertainties about political stability in many oil and gas producing countries, coal becomes more and more important in the coming years for its vast reserves and wide distribution all over the world. The technology of Underground Coal Gasification (UCG), converting in-situ, unmined coal into combustible gases, has continued to...
Coal combustion power plant Kolubara A has five thermal units with total installed capacity of 270 MW operates as a part of Public Enterprise which has planned to accept and apply the Clean Development Mechanism (new power plants on lignite and natural gas with higher energy efficiency as well as activities related to the rehabilitation and modernization of existing facilities). Two units were put...
Biomass cook stoves are widely used in developing countries. These stoves generally use wood fuel which represents about 60 to 86% of the total primary energy consumption in Africa; a few exceptions are observed in northern Africa countries and South Africa where this rate is lower. For some African regions, this rate raises up to 90–98% of the total consumption. In Benin, the estimations of the june...
Electricity market development (EMD) emerges to be a current concern following a shift of paradigm from EMD design with focuses upon energy as the key commodity to a need to deliver a sustainable low-carbon generation future. The feasible options of EMD are set to illustrate the interaction of the policy instruments, the market regulation and the sustainable investment environment. The economic benefits...
Hydroelectric power is the most important renewable energy technology in today's international. As a kind of renewable energy, water plays more and more important role in each country's energy development. This paper through the related theory method, query data and certain research, puts forward the development potential rating scale index system based on the water resources, and by using grey clustering...
It is an important prerequisite to determine the threshold of ecological water demand scientifically and reasonably for sustainable development of socio-economic and ecological environment. This paper analyzes the ratio of ecological water demand account for of the total runoff in Northwest arid areas, and combines with the instance of Manas River basin, proposes a reasonable threshold of ecological...
Based on the endogenous economic growth model, this paper presented a growth model with the consumption proportion of exhaustible resources and pollution control and then obtained the optimal economic growth path solutions. The prerequisites to optimal growth path are discussed based on these solutions. At last, some suggestions were given under the comparative static analysis of variables.
By use of the ecological footprint model, this paper calculated the ecological footprint and ecological carrying capacity of Jixi mining area in 2009. On that basis, the ecological deficit and surplus of this region have been analyzed in depth. The result of analysis demonstrated that the mining area's ecological economy is unsustainable. At the last, this paper proposed some suggestions and countermeasures,...
The collapse is a serious problem for the mining area in China. In order to improve the environment of mining area, this paper analyzes the presence of collapse area in Hebei province. This paper analyzes a series of environmental problems about mining area. And this paper gives some good way of restoring the mining area.
Based on the need of green mining development and large-scale development of ecological environmental damage as the background in China's coal resources, It analyzes the basis theory of mining resources, economy, people, environmental mutually relies on and restrict, green mining industry composition, characteristics and green mining industry. It gives the connotation and definition of green mining...
The article focuses on important of a low carbon economy development. Developing a low carbon economy as a coordinated social economy development. Energy security and the basic ways to address climate change, has been generally recognized around the world. The development of low-carbon economy, improving the proportion of renewable energy, can effectively reduce primary energy consumption of carbon...
Sustainable development is an urgent task that resource-exhausted cities are facing. The role and potential of urban spatial structure (USS) in achieving environmental, economic and social sustainability of resource-exhausted cities is vital. The first part of this paper discusses the basic connotation of sustainable USS and set up a framework for it which includes the urban spatial form (USF) and...
Shanxi Province is Rich in coal resources. For a long time, large-scale, extremely intense coal mining activities severely damaged the eco-geological environment in the mining areas, which restricts the regional social and economic sustainable development. This article discusses in detail the main types and features on eco-geological environment problems caused by coal mining in Shanxi Province, and...
Coal is a main primary energy sources in China. The regional coal transportation of closed loop in China reflects on inter- or intra- regional interaction of energy economy. This paper uses 0–1 linear programming to decompose the matrices of coal transportation on eight regions of mainland China to two hierarchies sub-matrices. We figure out the top-two hierarchies regional coal transportation of...
Coal is an important basic energy in China, the sustainable development of coal industry is relation to the national economic and security. After systemically analyzing the feature and the state of development, system model of the coal sustainable development was created by using the tool of system dynamic. Then different development modes are sifted and sorted by utilizing fuzzy comprehensive evaluation...
This paper analyzes the dialectical relationship between coal consumption and environment and economic growth; meanwhile discusses the reasonable coal consumption patterns based on constraints of economic growth and environment, which is of significance to ensure the sustainable development of the coal industry.
Energy is the lifeblood of economy development. The coordinated development of economy and energy is the initial mover of social development. The economy development, without the basis of energy, would be a river without sources, or a tree without roots. Therefore, only with the coordinated development of economy and energy, can society achieve steady progress.
Northwest slope of An Taibao open-pit mine in Shanxi province is under the condition of open-pit and underground combined mining, based on this slope project, the computation model is established for research and analysis using MIDAS / GTS and FLAC3D software, the deformation response characteristics of steep slope are researched by the method of numerical simulation. It is demonstrated that the steep...
