Abstract


The aim of this paper is to improve the basis for the comparison of energy products. The paper is based on results for hydropower, wind power and electricity from biomass, gas and coal, and discusses how system boundaries affect the results of the various energy indicators.
The internal ranking of cases within one electricity generation technology is dependent on the choice of energy indicator. These variations do not, however, alter the general ranking of the major technologies studied.
Future assessments are suggested to focus on a smaller set of energy indicators. CED should be included as it is the most universal indicator.

Keywords
