Moving from principles to action for energy supply that mitigates against climate change requires a long-term perspective. Energy infrastructure takes time to build up; new energy technologies take time to develop. Policy shifts often also need many years to take effect. In most world regions the transformation from fossil to renewable energies will require additional investment and higher supply costs over about twenty years

5.6 future investments in the heat sector

Also in the heat sector the Energy [R]evolution scenario would require a major revision of current investment strategies in heating technologies. Especially the not yet so common geothermal heat pump technologies need enormous increase in installations, if these potentials are to be tapped for the heat sector. Installed capacities for geothermal heat pumps need to increase to 42 MW and for solar thermal the capacity needs to increase even by 50%. Renewable heating technologies are extremely variable, thus the required investment costs can only roughly be calculated. The Energy [R]evolution scenario in total requires around € 3 billion to be invested in renewable heating technologies until 2050 (including investments for replacement after the economic lifetime of the plants) - approximately € 68 million per year.
