heat and cooling supply
Today, renewables provide around 39% of primary energy demand for heat supply in Latin America, the main contribution coming from the use of biomass.The availability of less efficient but cheap appliances is a severe structural barrier to efficiency gains. Large- scale utilisation of geothermal and solar thermal energy for heat supply will be largely restricted to the industrial sector.
In the Energy [R]evolution scenario renewables provide 81% of Latin America’s total heating and cooling demand by 2050.
- Energy efficiency measures can restrict the future primary energy demand for heat and cooling supply to a 29% increase, in spite of improving living standards.
- In the industry sector solar collectors, biomass/biogas as well as geothermal energy are increasingly replacing conventional fossil- fuelled 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 1,586 PJ/a is saved by 2050, or 17% compared to the Reference scenario.The advanced Energy [R]evolution version introduces renewable heating systems around five years ahead of the basic scenario. 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 66% by 2030 and 98% by 2050.
