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 24% of energy demand for heat and cooling supply in China, the main contribution coming from the use of biomass. In the Energy [R]evolution scenario, renewables provide 65% of China’s total heating and cooling demand by 2050.

  • Energy efficiency measures will restrict the future energy demand for heat and cooling supply in 2050 to an increase of 12%, compared to 58% in the Reference scenario, in spite of improving living standards.
  • In the industry sector solar collectors, biomass/biogas as well as geothermal energy are increasingly substituted for conventional fossil-fired 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 efficiency measures save 12,459 PJ/a by 2050, or 29% compared to the Reference scenario. The advanced Energy [R]evolution version introduces renewable heating and cooling systems around five years ahead of the basic scenario. China can use concentrated solar energy to generate heat for industrial processes in its north western provinces. Efficient use of heating and architecture which avoids the need for air conditioning can reduce the overall demand. 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 33% by 2030 and 87% by 2050.
