| Summary/Abstract |
Energy efficiency and energy conservation are the cornerstones of win-win strategies for reducing emissions while fostering economic development. Renewable energies can technically contribute to practically all sectors of energy demand, that is, fuel for transportation, electricity, low temperature heat for space heating and hot water and, to a limited degree, to high temperature process heat. However, costs and variability are the two major security concerns regarding renewable energies. An improvement of energy security by using renewable energies is possible but it causes additional costs. However, a sufficiently widespread variety of energy sources implies the acceptance of a certain spread of costs in any case. This means that efforts to improve energy security do not come for free. More secure energy systems require higher costs and thus, higher energy prices.
