Greece spends billions importing oil and gas every year – so becoming an energy exporter once felt like a distant dream. Green energy is changing that.

Today, about 45 per cent of its electricity comes from renewables – and roughly 20 per cent of what it produces is exported, primarily to Italy and, to a lesser extent, neighbouring Balkan countries.

But momentum has hit a ceiling. Renewable capacity now far outstrips domestic demand. Greece is curtailing significant amounts of green power simply because there aren't enough buyers.

Exports aren't picking up the slack either, as neighbouring countries are producing their own cheap green energy.

Speaking at the Energy Transition Summit in Athens on 13–14 May, one industry insider was blunt about what that means for Greece's renewable rollout.
