Renewable Energy Sources (RES) dominated Greece's fuel mix in electricity generation for the whole of 2022. In particular, wind and photovoltaic parks, biomass units reached 35% and together with hydroelectric plants 41%. In fact, the gradual increase has been recorded for five years, as from approximately 10,000 GWh (gigawatt hours) provided by RES (excluding hydroelectric) in 2018, they increased to 10,600 GWh in 2019, to 13,700 GWh in 2020, to 16,100 GWh in 2021 and reached 17,500 GWh in 2022.

The road for the utilization of the rich solar and wind potential of the Aegean islands for the production of "green" electricity is generated by the electrical interconnections launched by the Independent Electricity Transmission Operator.

Greek renewable energy sources (RES) achieved a double record on September 14, meeting the highest rate of demand both nationally and at European level that day, according to Independent Power Transmission Operator (ADMIE) data.
