Global scenarios of energy provision with zero net emissions of greenhouse gases are considered. The scenarios assume the same demand for energy services and a high degree of emphasis on energy efficiency, with supply options clean fossil fuels, safe nuclear power, centralised or decentralised...

In contrast to conventional energy modeling made on a national basis, we consider energy use and supply per unit of land area. This is particularly suited for dealing with dispersed energy resources such as renewable energy, and by making the match of demand with supply on this basis in a...

The official Danish energy plan “Energy 21” calls for a very high penetration of wind energy in the electricity sector. This will put issues of fitting a variable energy source into a stable supply system in focus. The present study investigates the role that collaboration with the...
