[6] The contribution of non-hydroelectric renewable energy sources (RES) to the gross final electricity consumption accounted for 24.5% in 2016,[7] while hydroelectric power represented approximately 25% by installed capacity.
[8] As of the 2023 International Energy Agency (IEA) report, Greece has made notable strides in reducing its reliance on lignite for electricity generation.
The shift away from lignite is complemented by increased generation from natural gas and renewables like wind and solar photovoltaics, aligning with the country's net-zero emissions goal by 2050.
[11] In 2011 the Greek government approved the start of oil exploration and drilling in three locations within Greece,[12] with an estimated output of 250 to 300 million barrels over the next 15 to 20 years.
[13][14] The Ministry of the Environment, Energy and Climate Change announced that there was interest from various countries (including Norway and the United States) in exploration,[14] and the first results regarding the amount of oil and gas in these locations are expected in the summer of 2012.
[23] Greek State allocated 350 MW of electricity to biomass - bio-fuels[24] Solar power in Greece has been driven by a combination of government incentives and equipment cost reductions.
The installation boom started in the late 2000s with feed-in tariffs has evolved into a market featuring auctions, power purchase agreements, and self-generation.
