heat and cooling supply

Today, renewables provide around 40% 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 83% of Latin America’s total heating and cooling demand in 2050.

Energy efficiency measures restrict the future primary energy demand for heat and cooling supply to a 60% 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 fuel-fired heating systems.
A shift from coal and oil to natural gas in the remaining conventional applications leads to a further reduction of CO2 emissions.
