Renewables currently provide 55% of India’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 68% of India’s total heat demand in 2030 and 91% in 2050.
- Energy efficiency measures can decrease the specific demand in spite of improving living standards.
- For direct heating, solar collectors, new biomass/biogas heating systems as well as geothermal energy are increasingly substituting for fossil fuel-fired systems and traditional biomass use.
- A shift from coal and oil to natural gas in the remaining conventional applications will lead to a further reduction of CO2 emissions.
Table 5.44 shows the development of the different renewable technologies for heating in India over time. After 2020, the continuing growth of solar collectors and a growing share of geothermal heat pumps will reduce the dependence on fossil fuels and biomass.
