We discuss the role played by interregional power transmission on the basis of recent scenario work. In a project dealing with long-term planning for energy efficiency and renewable energy in Europe [described thoroughly in 1-4], we modelled a scenario for the present 15 EU countries' energy...

The amount of wind power in the world increases fast. The background for this development is improved technology, decreased costs for the units and an increased concern of the environmental problems of competing technologies such as fossil fuels. For the future, it is now interesting to evaluate...

The Swiss Association of Producers and Distributors of Electricity (VSE) identified a number of possible supply mix options to meet the future electricity demand in Switzerland. In this context, PSI, in co-operation with ETHZ, analysed environmental inventories for the selected electricity...

The Life Cycle Assessment (LCA) performed for the China Energy Technology Program (CETP) has established streamlined environmental inventories of coal, nuclear, natural gas, and wind energy systems for supply of electricity to Shandong province with a 20 years time horizon. This paper deals with...

In recent years, human activities have begun to seriously influence local and global environments. Under the circumstances, Life Cycle Assessment (LCA) is expected to be a powerful tool in evaluating impacts on environments. However, LCA is not yet established methodologically or formulated...

Oleaginous plants such as Jatropha Curcas Linnaeus (JCL), not intended for human consumption but used for biodiesel production, could contribute to beneficial outcomes. This plant grows on poor land (arid and marginal land) and is drought resistant. Jatropha Curcas is native to South America and...

A fuzzy logic based method of energy efficiency assessment of Biomass-based Fuel Ethanol (BFE) production is introduced in this paper. Energy relevant inventory variables are defined and described by fuzzy sets representing the differences in energy inventory data between the BFE system and its...

High energy consumption and the world population increase will lead to shrinking reserves of fossil fuels. Concern about carbon dioxide emissions may discourage widespread dependence on fossil fuels and encourage the development and use of renewable energy systems employing a variety of...

Life Cycle Assessment (LCA) is an instrument to quantify environmental impacts of the entire energy supply chain. According to the LCA, an appropriate indicator system should comprise all steps of a system's life cycle: production, operational and disposal processes ("cradle-to-grave")....
