The scenario method is used to investigate whether or not an energy supply system entirely based upon renewable energy sources (solar radiation, wind, biomass, environmental heat and hydro) can supply the energy globally required by the mid-21st century. A geographical information system (GIS)...

An approach to energy systems modelling is presented. It employs a mixture of non-linear programming techniques considered suitable for the particular structure of energy models, in order to overcome the problems encountered in optimisation with a non-trivial objective function topology, e.g....

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...
