Overview

It can be stated

The costs of electricity don’t have to lie far above today’s costs even if very conservative assumptions are made. At today’s prices for all components, the costs of electricity don’t have to be higher than from a newly erected combined-cycle gas power plants and could be even lower than the current prices of electricity at the cheap base load electricity traded e.g. at the European Energy Exchange. The annual difference in cost compared with the current national bill for electricity, which typically may account for roughly 2 to 3% of the gross national product, would – if at all – only impose a few per mill of the gross national product as an additional burden on the industrial countries within the supply area of the scenarios, thereby constituting a highly rational alternative to the predictable consequences of climate change and declining fossil fuel resources. Foreseeable cost reductions – particularly for renewable energy technologies – make a spacious international renewable energy system both conceivable and potentially more economic than all current means of providing electrical energy. However, the costs are dependent on the future system configuration, and could be reduced by ongoing technical progress, or be negatively influenced by wrong energy policies.
