energy supply for heating and cooling
Today, renewables meet 47% of the ASEAN region’s energy demand for heating and cooling, the main contribution coming from the use of biomass. Dedicated support instruments are required to ensure a dynamic development in particular for renewable cooling technologies (e.g. solar cooling) and renewable process heat production. In the Energy [R]evolution scenario, renewables provide 52% of the ASEAN region’s total heat demand in 2030 and 78% in 2050.
- Energy efficiency measures help to reduce the currently growing energy demand for heating and cooling by 28% in 2050 (relative to the reference scenario), in spite of improving living standards and economic growth.
- In the industry sector solar collectors, geothermal energy (incl. heat pumps) as well as electricity and hydrogen from renewable sources are increasingly substituting for fossil fuel-fired systems.
- A shift from coal and oil to natural gas in the remaining conventional applications leads to a further reduction of CO2 emissions.
Table 5.2 shows the development of the different renewable technologies for heating and cooling in the ASEAN region over time. Up to 2040 biomass will remain the main contributors of the growing market After 2040, the continuing growth of solar collectors (also for solar cooling), a growing share of geothermal and environmental heat as well as heat from renewable hydrogen will reduce the dependence on fossil fuels.
