Tilos, Greece: the first island in the Med to run entirely on wind and solar power

Tiny Tilos, in the Dodecanese, is a pioneering nature reserve. Now, Greece's 'green island' is set to be powered by renewable energy

You're more likely to run into friendly partridges, rare orchids and endangered eagles than people as you trek around Tilos. The entire Dodecanese island is a nature reserve, with more than 150 species of resident and migratory birds, over 650 plant varieties, and a permanent population hovering around 500. Tilos owes its extraordinary biodiversity to a network of underground springs that feed five wetlands - but also to the late mayor, Tassos Aliferis, a committed environmentalist who earned Tilos its reputation as "Greece's green island".
