1 Fundamentals of sustainable energetic. (October 2011) Energy Consumption and Energy Sources in Germany by 2050 Author 1 Author 2 Author 3

2 Status quo  Germany today Total area: 357,012m² Population: 82 mill. GDP 2.4trillion in 2010 Electricity imports: 42.1 TWh Electricity exports: 59.1 TWh  Energy resources Coal Oil Natural gas Nuclear Energy Renewable Energy


4 Reduction of Energy Consumption  Use of all available eco-friendly technologies  Lights. Reducing of street lights, eliminate lights- advertisement for reduction of energy consumption and light-pollution.  Give feed-back on energy consumption, at least a monthly bill  Enable the consumer to level-out the energy consumption over the day to make use of smart grids  Combustion of fossil fuels for heating is inefficient as electrical heating

5 Transport I  Tailormade transportation according to the needs and the traffic density (rush hour – rural areas)  Cities: public transport, supported by measures like city-toll (maut)  Rural area:Higher efficiency of infrastructure reduces the need of transportation, no need for long distances. In rural areas, efficient cars can be justified

6 Transport II  90% reducing of fossil fuel demand by new technologies and efficiency for cars (1-3liter cars, electro cars, etc.)  Electro cars used also as electricity storage  Reduce energy need by decreasing of traffic  Offer transport resources at the point of need, i.e. car sharing, public transport, bicycles  Get away from the attitude one consumer-one car. That reduces the problems of stationary traffic

7 Housing  Home heating. Zero energy homes (ZEH) – good insulation, solar or/and horisontal ground source heat pumps for water and room heating, solar or/and wind electricity production by house, controllers for energy and water consumption at homes  Electricity. Connect homes to electricity system – use energy from system if needed and donate energy to the system if it is overproduced by house  Water. Rain water collection for household needs  Create incentives for smart use of energy, i.e. flexible tarifs

8 Industry  Demographic change leads to decrease of industry production  Energy intensive industry sectors decline  Decrease of production (there are too many things produced we don´t really need)  Introduce more measures, based on the footprint of a production. I.e. ease investment in greener technologies through tax-legislation  Food. Use local food. Stop food waste and so reduce its production and transportation energy needs. Save territory for wild life.  Paper. Eliminate paper advertisement, packaging. Save forests and CO2/O2 balance.

9 People I  Parks. Plant more parks and forests to reduce CO2 amounts, to clean up the air  Waste. Waste sorting and their reuse or recycling  Introduce a master plan to make the people think green in their decisions  give a feed-back in their taken decisions and make them benefit financially from it

10 People II  Introduce the ecological footprint in tax-legislation  Do the right thing and benefit from it  Impose certain taxes on efficient usage of energy. Higher taxes on fossil fuels and unjustified usage

11 Demography I  ~15 Million people less until 2050  In Germany by 2050, the years with a strong birth rate are becoming erased due to their age  Introduce measures to help supporting the scarcely populated regions and optimize it under energy- saving aspects

12 Demography II  Industries with high energy consumption are decreasing generally in Germany and are not labour intensive  Change to the service industry, which is labour intensive solves the labour market problem  Environmental- and labour market issues are disconnected

13 How Much Energy Does Germany Need by 2050  Natural- and biogas for “high value energy” – industry  Heat pumps, geothermal and solarthermic sources for “low value energy” – housing, service sector  transportation

16 Possible Energy Sources  Solar PV. Even more potential than in the following graph  Solar heating. Especially for housing  Ground source heat pumps for housing limited by regional access  Wind. Increase mainly in offshore wind parks  Hydropower. Nearly constant amount of power plants  “Sustainable” biomass. No new areas of cultivation, but areas of compensation

18 Conclusion  There is no “right answer”, complex possibilities  Changes are introduced by the people and require a change in attitude  A master-plan for the introduction of new technologies according to the expected lifetime  Close consideration of international collaboration (im- and export)  Smart grids and storage can contribute to the need of installed power plants
