Sustainability Appraisal Of Residential Energy Demand And Supply: A Life Cycle Approach Including Heating, Electricity, Embodied Energy And Mobility

The Energy Roadmap 2050 of the European Union aims at 80% to 95% greenhouse gas reduction until 2050 [1]. Energy saving, energy efficiency and the shift towards renewable energy supplies have to be jointly applied in order to reduce the environmental overshoot of the current energy systems. This environmental overshoot is due to the high energy intensity of society and the extensive use of fossil and nuclear energy sources [2]-[4]. All sectors of society and economy have to contribute to achieve this shift in energy supplies.
