Energy Mix
78
Processing operations are energy-intensive and estimated to be 6.2 % of total global energy consumption – energy represents a third of a company ’ s total cost base . Energy mix considerations include : social and reputational implications of choosing energy sources ; viability of energy sources ( remote locations ) and management of the availability of energy over entire mine life while counteracting fuel price volatility . To date , mining operations have largely relied on fossil fuels to run equipment and electricity for processing . To minimise risk , companies are opting for a mix of fossil fuels , hydroelectricity and renewable energy . In his EY blog , Dr . Ali G . Madiseh , Canada Research Chair in Advanced Mine Energy Systems , maintained the solution is the development of ultra-efficient energy systems for mining operations to make them greener , less expensive and more sustainable by preventing energy wastes and taking advantage of the renewable energy sources available on-site ( wind and solar for power and geothermal for heating ).
