5.5 heating supply
Today, renewables meet 44% of Finland’s heat demand, the main contribution coming from the use of biomass. The expansion of the existing district heating network is an indispensable infrastructure element for the large scale utilization of geothermal and solar thermal energy. Dedicated support instruments are required to ensure a dynamic development. In the Energy [R]evolution scenario, renewables provide 72% of Finland’s total heat demand in 2030 and 94% in 2050.
- Energy efficiency measures help to reduce the currently growing energy demand for heating by 51% in 2050 (relative to the reference scenario), in spite of improving living standards.
- In the industry sector solar collectors, geothermal energy (incl. heat pumps), and hydrogen and electricity 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 in Finland over time. Up to 2050 biomass will remain the main contributor of the growing market share, although total biomass consumption for heating purposes decreases.
After 2020, the continuing growth of solar collectors and a growing share of geothermal heat pumps will reduce the dependence on fossil fuels.
