Mathraki
The Diapontian Islands, also known as the Diapontia Islands, are a group of Greek islands located in the Ionian Sea, northwest of Corfu. The main inhabited islands in this archipelago are Othoni, Ereikoussa, and Mathraki. The Diapontian Islands do not have conventional electricity production units or renewable energy sources (RES). Instead, they rely solely on their interconnection with Corfu for electricity supply. Heating on all three islands is primarily achieved using diesel, wood, air conditioning, and resistive heaters.
