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

heat and cooling supply

Renewables currently provide 3% of Transition Economies’ energy demand for heat supply, the main contribution coming from the use of biomass.The lack of modern and efficient district heating networks is a barrier to the large scale utilisation of geothermal and solar thermal energy. Dedicated support instruments are required to ensure a dynamic development. In the Energy [R]evolution scenario, renewables provide 74% of Transition Economies’s total heating demand in 2050.

  • Energy efficiency measures can decrease heat demand by 37% in spite of improving living standards.
  • For direct heating, solar collectors, biomass/biogas as well as geothermal energy are increasingly substituting for fossil fuel-fired systems.
  • A shift from coal and oil to natural gas in the remaining conventional applications will lead to a further reduction of CO2 emissions.

The advanced Energy [R]evolution version introduces efficiency measures e.g. via strict building standards and renewable heating systems around 5 years ahead of the Energy [R]evolution scenario. Compared to the Reference scenario, 9101 PJ/a or 37% are safed by 2050. Solar collectors and geothermal heating systems achieve economies of scale via ambitious support programmes five to ten years earlier, resulting in a renewable share of 50% by 2030 and 89% by 2050.
