1.7 japan: heating and cooling supply
Renewables currently provide 3% of Japan’s energy demand for heat supply, the main contribution coming from biomass. Dedicated support instruments are required to ensure a dynamic future development. In the Energy [R]evolution scenario, renewables provide 52% of Japan’s total heating and cooling demand in 2050.
- Energy efficiency measures can decrease the current demand for heat supply by 38%, in spite of improving living standards.
- For direct heating, solar collectors, biomass/biogas as well as geothermal energy are increasingly substitute 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 case introduces renewable heating and cooling systems around 5 years ahead of the Energy [R]evolution scenario. Solar collectors and geothermal heating systems achieve economies of scale via ambitious support programmes 5 to 10 years earlier and reach a share of 36% by 2030 and 71% by 2050.
