Total final energy consumption of the industry sector has steadily increased from a 1993 low of 698,108 TJ to 1,001,498 TJ in 2019, largely driven by the overall performance of the economy., However, the emissions picture has been mixed, with vacillations driven by global economic pressures, electricity supply constraints, changes in product output, a growing service sector and slow annual GDP growth., Since 2017, in particular, fuel combustion emissions across all sectors have been decreasing due in part to the slowing economy (pre- and during COVID).,,,
Process emissions from the Industrial Processes and Product Use (IPPU) sector contributed on average, 7% of total national emissions (excl. LULUCF) between 2000 and 2017. The main drivers of emissions in the IPPU sector are the metal industries – principally the production of iron, steel and ferroalloys – and the mineral industries. More efficient energy and material use, and minimising waste, will be key to cutting these emissions, but the sector remains amongst the hardest to decarbonise.
To decarbonise the industrial sector, the share of electricity (powered by renewable energy) used in the sector would need to increase from 38% in 2019, to approximately 49% by 2030 and to between 69 to 82% by 2050. When combined with hydrogen and biomass, electrification penetration should reach up to 95% by 2050.
South Africa’s Post-2015 Energy Efficiency Strategy sets sectoral energy intensity improvement of 15% for industry and mining sectors by 2030, and aims to achieve this by implementing minimum energy performance standards (MEPS), amongst others.
