Turkey expects a very large growth in energy demand, especially for electricity and natural gas. Today, Turkey's energy production meets nearly 48% of the total primary energy demand. Total primary energy demand will reach 98 Mtoe in 2001 and 308 Mtoe in 2020. Import of primary energy will reach 226 Mtoe and production of primary energy will increase 81 Mtoe in 2020. As seen, Turkey is an importer country for primary energy. Turkey's indigenous energy sources are limited, and the country is heavily dependent on the import of primary energy from abroad. The growth of Turkey's industry is giving rise to a substantial increase in energy demand. In this paper, the primary energy production and sectoral consumption in Turkey is investigated. Further, a sectoral energy demand projection in Turkey is given until 2020. (C) 2002 Elsevier Science Ltd. All rights reserved.
