Electric energy production in Greece is dominated by the state-owned Public Power Corporation (known mostly by its acronym , or in English DEI). In 2009 DEI supplied for 85.6% of all electric energy demand in Greece, while the number fell to 77.3% in 2010. Almost half (48%) of DEI's power output is generated using lignite, a drop from the 51.6% in 2009.
Twelve percent of Greece's electricity comes from hydroelectric power plants and another 20% from natural gas. Between 2009 and 2010, independent companies' energy production increased by 56%, from 2,709 Gigawatt hour in 2009 to 4,232 GWh in 2010.
In 2012, renewable energy accounted for 13.8% of the country's total energy consumption, a rise from the 10.6% it accounted for in 2011, a figure almost equal to the EU average of 14.1% in 2012. 10% of the country's renewable energy comes from solar power, while most comes from biomass and waste recycling. In line with the European Commission's Directive on Renewable Energy, Greece aims to get 18% of its energy from renewable sources by 2020.
In 2013, according to the independent power transmission operator in Greece () more than 20% of the electricity in Greece has been produced from renewable energy sources and hydroelectric powerplants. This percentage in April reached 42%. Greece currently does not have any nuclear power plants in operation; however, in 2009 the Academy of Athens suggested that research in the possibility of Greek nuclear power plants begin.
Almost two-thirds of the Greek people live in urban areas. Greece's largest and most influential metropolitan centres are those of Athens and Thessaloniki, which is commonly referred to in Greek as the "" (lit. "co-capital"), with metropolitan populations of approximately 4 million and 1 million inhabitants respectively. Other prominent cities with urban populations above 100,000 inhabitants include those of Patras, Heraklion, Larissa, Volos, Rhodes, Ioannina, Agrinio , Chania, and Chalcis.
The table below lists the largest cities in Greece, by population contained in their respective contiguous built up urban areas, which are either made up of many municipalities, evident in the cases of Athens and Thessaloniki, or are contained within a larger single municipality, case evident in most of the smaller cities of the country. The results come from the preliminary figures of the population census that took place in Greece in May 2011.
