Through necessity, Chile (supported by China), has developed various renewable energy projects to provide power for mining.

"As the scale of China’s renewable power expands, so the unit costs decline. This is the iron law of the learning curve. It is advantageous for China, of course, but it also means that the same lower costs can be enjoyed by other countries – in this case, Chilean power producers supplying renewable power to the minerals sector. The underlying technology is diffused around the world, and competition ensures that the lower costs are shared by all."
