Europe has a seemingly infinite amount of coal (same as everyone else), but obviously it's not exactly what anyone really wants (gas and even oil is more climate friendly than coal sadly).

North Sea oil and gas are long past its prime, Norwegian supply is already nearly as expensive as LNG shipped from half the world away. The ideal gas station is Siberia, but that is what it is currently.

So, dunno, what's left, the Arctic? Frack the polar bears?
