The Diavik Diamond Mine, owned by Rio Tinto, has pioneered a transition to renewable energy by installing a 3.5 MW solar power station in northern Canada, a departure from the typical high-emissions mining industry. This facility is the largest off-grid solar project in Canada's territories, generating 4.2 million kilowatt-hours annually, saving one million liters of diesel, and reducing CO₂ emissions by 2,900 tonnes annually. As the mine nears closure in 2026, its solar and wind power systems will continue to power operations post-closure, illustrating a significant shift towards sustainable mining practices.
