The wave of interest in solar power across Europe has now touched Greece, and in a big way. The Mediterranean country of over ten million inhabitants plans to construct Earth’s biggest solar farm. Estimated to cost €600 million ($822 million), the project will cover 1,285 acres of depleted coal mines in the northern city of Kozani.

The solar project at Kozani will also lesson Greece’s dependence on lignite coal, a heavily-polluting energy source that accounts for about half of Greece’s generated electricity.​

Total output of the completed solar installation is estimated to be 200 megawatts (MW).
