As a result, the deployment of renewables has increased considerably, particularly of solar PV, which in 2016 outstripped the growth in any other form of new power generation, with renewables reaching nearly a quarter in the world’s electricity generation (IEA, 2017b). Based on estimates, improved energy management through the scaled-up use of renewables can reduce mining companies’ energy costs by 25% for existing operations and up to 50% for new mines (Deloitte, 2017). There is scope for further research to look at issues related to the energy transition of processing facilities (Section 3.2).
