Turkey has an adequate amount of water in general, but it is not always in the right place at the right time to meet present and anticipated needs. Turkey has 665.000 ha of inland waters, excluding rivers and small streams. There are 200 natural lakes, with a total area of 500.000 ha, and 775 dam lakes and ponds with a total surface area of 165.000 ha [2,20]. On the other hand, Turkey has made a positive step towards implementing future energy efficiency policies by drafting the Energy Efficiency Strategy Paper, which includes indicative sectoral targets. It was recently conveyed to the prime minister’s office via the Ministry of Energy and Natural Resources (MENR), for formal approval by the High Planning Council (YPK). This paper deals with energy management and Southeastern Anatolia Project (GAP) in Turkey.
