Mining can be divided into two main energy-use categories: off-grid and grid-connected. Traditionally, most off-grid mining operations depend on fossil fuels such as diesel, heavy oils, and coal for on-site generation and haulage [6].However, grid-connected mining operations are also reliant on fossil fuels, to some degree.
