and wheat (2.07 million tons, ranked 35th in the world). Other important agricultural products are: sunflower, sugar beet, soybean, potato, apple, mutton, pork meat, beef, poultry and dairy. There are 56,000 ha of vineyards in Serbia, producing about 230 million litres of wine annually. Most famous viticulture regions are located in Vojvodina and Šumadija. Energy The energy sector is one of the largest and most important sectors to the country's economy. Serbia is a net exporter of electricity and importer of key fuels (such as oil and gas). Serbia has an abundance of coal, and significant reserves of oil and gas. Serbia's proven reserves of 5.5 billion tons of coal lignite are the 5th largest in the world (second in Europe, after Germany). Coal is found in two large deposits: Kolubara (4 billion tons of reserves) and Kostolac (1.5 billion tons). Despite being small on a world scale, Serbia's oil and gas resources (77.4 million tons of oil equivalent and 48.1 billion cubic meters, respectively) have a certain regional importance since they are largest in the region of former Yugoslavia as well as the Balkans (excluding Romania). Almost 90% of the discovered oil and gas are to be found in Banat and those oil and gas fields are by size among the largest in the Pannonian basin but are average on a European scale. The production of electricity in 2018 in Serbia was 38.3 billion kilowatt-hours (KWh), while the final electricity consumption amounted to 28.1 billion kilowatt-hours (KWh). Most of the electricity produced comes from thermal-power plants (71% of all electricity) and to a lesser degree from hydroelectric-power plants (24%) and wind energy (3%). There are 6 lignite-operated thermal-power plants with an installed power of 3,936 MW; largest of which are 1,502 MW-Nikola Tesla 1 and 1,160 MW-Nikola Tesla 2, both in Obrenovac. Total installed power of 9 hydroelectric-power plants is 2,831 MW, largest of which is Đerdap 1 with capacity of 1,026 MW. In addition to this, there are mazute and gas-operated thermal-power plants with an installed power of 353 MW. The entire production of electricity is concentrated in Elektroprivreda Srbije (EPS), public electric-utility power company. The current oil production in Serbia amounts to over 1.1 million tons of oil equivalent and satisfies some 43% of country's needs while the rest is imported. National petrol company, Naftna Industrija Srbije (NIS), was acquired in 2008 by Gazprom Neft. The company's
