What is Algeria's pathway to limit global warming to 1.5°C?
Buildings
Decarbonising the building sector
The buildings sector accounted for 13% of Algeria’s emissions in 2022.1,2 Fossil gas made up 72% of the mix, oil 10%, and electricity (including a very small share of biomass) met the remaining 18% of demand.3
The Deep Electrification pathway, which best captures the potential for rapid electrification to drive fossil fuels out of the energy system, relies the most on electricity to phase out fossil fuels in the buildings sector. By 2050, the share of electricity rises to 93%. The remainder of energy demand in the buildings sector is addressed through heat (e.g. through harnessing Algeria’s significant geothermal potential).4 As a result of this deep electrification, oil is phased out of the buildings sector by 2050, though gas continues to play a small role (4% of energy demand). The Deep Electrification pathway sees the highest final energy demand by 2050, at 710 PJ/yr.

The Minimal CDR Reliance pathway also primarily relies on electricity to push fossil fuels out of the system and align with 1.5°C, as well as slows the increase in final energy demand further than is achieved under the Deep Electrification pathway. Electricity makes up 34% of the buildings sector’s energy mix in 2030, though the role of heat (e.g. geothermal) and biomass increases through the 2030s and 2040s. Together they account for 8% of the energy mix in 2050, while electricity meets 84%. Similar to the Deep Electrification pathway, oil is mostly phased out of the system by 2050, though fossil gas supplies 7% of demand.
