Agios Efstratios or Saint Eustratius (Greek: Άγιος Ευστράτιος), colloquially Ai Stratis (Greek: Άι Στράτης) is a small Greek island in the northern Aegean Sea about 30 km southwest of Lemnos and 80 km northwest of Lesbos. Together with Lemnos and nearby islets it forms the regional unit of Lemnos, part of the Greek archipelagic region of the North Aegean.
The island was named after Saint Eustratius[disambiguation needed], who lived on the island in the 9th century as an exile, because he was opposed to the iconoclastic policies of the Byzantine Emperor Leo the Armenian. His grave is still being shown by the inhabitants.
Agios Efstratios is quiet, isolated and dry, with a population of approximately 300 people. The climate is arid, with little rainfall during the winter months and long, hot summers. The landscape is mostly rocky, with scarce and low vegetation. Crops are insignificant; the surrounding sea, however, is rich in fish which are fished by local fishermen. There are numerous beaches on the island such as Agios Antonios, Lemonies, Avlakia and others, most of which are reached by caique. Agios Efstratios Island is linked by boat with Limnos, Agios Konstantinos[disambiguation needed], Kymi and Kavala.
Recent political history 
The island was used to house political prisoners in internal exile during the 1930s. On 19 February 1968, an earthquake (7.1 on the Richter scale) demolished most of the houses, which were replaced by concrete prefabricated buildings laid out in a military-like camp formation. Nonetheless, the island retains a very attractive capital, also called Agios Efstratios, while preserving a rather unspoiled Mediterranean environment with pristine beaches. It is mostly a place for relaxation and meditation. In the 1970s, the island was again used as an offshore prison for political dissidents. One of its most famous prisoners was Mikis Theodorakis, political activist and musical composer.
Greece's first green island 
Athens News Agency  reporteded that, on 4 June 2009, at a two-day international conference in Athens on "Climate Change and Challenges for the Future Generations" under the patronage of UNESCO, Greece's Development Minister Kostis Hatzidakis said that Agios Efstratios would soon become the country's first "green" island, entirely powered by renewable energy sources (RES), its residents relying on solar and wind generated energy and moving around the island on bicycles and in electric cars. Hatzidakis said a €10 million project would be implemented by 2010. At the same conference Professor Philippos Tsalidis, Development Ministry General Secretary for Research and Technology, said that although Greece's energy needs currently required strategic reliance on natural gas, Aghios Efstratios, could serve as a global model for 100% reliance on RES. Agios Efstratios is included in the European Union's Natura 2000 network of nature protected areas.
