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

Today, renewables provide around 49% of primary energy demand for heat and cooling supply in Other Developing Asia, the main    6 contribution coming from the use of biomass.The availability of less efficient but cheap appliances is a severe structural barrier to efficiency gains. Large-scale utilisation of geothermal and solar thermal energy for heat supply will be largely restricted to the industrial sector.
In the Energy [R]evolution scenario renewables provide 72% of Other Developing Asia’s total heating and cooling demand by 2050.

  • Energy efficiency measures can restrict the future primary energy demand for heat and cooling supply to a 45% increase, in spite of improving living standards.
  • In the industry sector solar collectors, biomass/biogas as well as geothermal energy are increasingly replacing conventional fossil- fuelled heating systems.
  • A shift from coal and oil to natural gas in the remaining conventional applications leads to a further reduction of CO2 emissions.

In the Energy [R]evolution scenario 3,566 PJ/a is saved by 2050, or 19% compared to the Reference scenario.The advanced version introduces renewable heating systems around five years ahead of the basic scenario. Solar collectors and geothermal heating systems achieve economies of scale via ambitious support programmes five to ten years earlier, resulting in a renewables share of 58% by 2030 and 85% by 2050.
