Mining companies are often considered as not willing to make changes towards environmental friendly solutions, but that perception may be changing as some companies turn to solar & wind energy to cut costs and improve their corporate sustainability.
Many of these bottlenecks actually do not reflect the reality today. There are solutions for external financing such as rental or power providers selling the energy to the mine. Flexible rental solutions allows at the same time for renewable energy solutions for mines with a shorter remaining lifetime. On the technical side improvements of diesel generators will improve penetration as well as enhancements of hybrid controlling units.
