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. Installed capacities need to increase drastically for solar thermal heating systems, if their potential is to be tapped for the heat sector. Other technologies as geothermal heat pumps and hydrogen from renewable sources (for high temperature process heat) are not yet or only rarely used in Mexico today. However, they will play an important role for Mexico’s heat supply in 2050. Capacity of biomass technologies, which are already rather wide spread today will increase only slightly, but will remain a main pillar of heat supply.

Renewable heating technologies are extremely variable, from low tech biomass stoves and unglazed solar collectors to very sophisticated enhanced geothermal systems and solar themal district heating plants with seasonal storage.Thus it can only roughly be calculated, that the Energy [R]evolution scenario in total requires around $ 456 billion to be invested in renewable heating technologies until 2050 (including investments for replacement after the economic lifetime of the plants) - approximately $ 11 billion per year.
