IGF Case Study: Achieving a Successful Post-Mining Transition With Renewable Energy
The use of renewable energy technologies– including solar panels, wind turbines, and electric vehicles–has many benefits, from mitigating greenhouse gas emissions to diversifying the energy mix to reducing our dependence on fossil fuels.
In recent years, the mining industry has undertaken efforts to contribute to the renewable energy transition, including through the conversion of brownfields to brightfields. This entails transforming contaminated land or abandoned mine sites (brownfields) into areas that can generate renewable energy, most typically in the form of solar developments (brightfields). This practice not only contributes to the renewable energy transition but also serves to convert what would be a financial liability into an economic opportunity. Brownfield to brightfield conversion has increased significantly in recent years; for example, within the United States, the government vetted more than 80,000 brownfields for renewable energy development.
Former mine sites can be suitable locations for solar and wind power projects. The remediation process—the process of restoring the land—involves clearing the sites of any above-ground structures. Brownfields are then typically converted into sites suited to the installation of solar arrays and wind turbines. Former mine sites are also typically located in close proximity to power lines, which ultimately makes connecting to the grid easier.
This report from the Intergovernmental Forum on Mining, Minerals, Metals and Sustainable Development (IGF) shares case studies of renewable energy conversion from two different IGF member jurisdictions, both of which involved transforming a former mine site into a space used for renewables. The first case study outlines the efforts of SunMine, a solar farm within the interior of British Columbia. The second case study presents the conversion of a former coal mine site into a wind park in Ruhr, Germany.

Can we say ‘no’ to fuel subsidies?
Not a single country in the world prices fossil fuels "fairly". The fossil fuel industry benefits from subsidies worldwide – $11m every minute. Subsidies on oil, gas and coal amounted to $5.9 trillion in 2020, which may go up to $6.4 trillion in 2025, estimates the International Monetary Fund.

While the Canadian government is working on a plan to phase out public financing to the fossil fuel sector, the high-profile announcement may only result in a change in the way Ottawa supports the industry, not a reduction in the dollars that change hands, according to an analysis last week in the Globe and Mail.
