Solar energy

Solar energy is radiant light and heat from the Sun harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture and artificial photosynthesis.

It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on the way they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

The large magnitude of solar energy available makes it a highly appealing source of electricity. The United Nations Development Programme in its 2000 World Energy Assessment found that the annual potential of solar energy was 1,575–49,837 exajoules (EJ). This is several times larger than the total world energy consumption, which was 559.8 EJ in 2012.

Solar Energy (journal)

Solar Energy is a peer-reviewed scientific journal covering research on solar energy such as photovoltaics and solar heating, but also its indirect usages like wind power or bioenergy. It is published by Elsevier on behalf of the International Solar Energy Society. The editor-in-chief is Yogi Goswami. According to the Journal Citation Reports, the journal has a 2013 impact factor of 3.541.

Romania (ⁱ/roʊˈmeɪniə/ roh-MAY-nee-ə; Romanian: România [romɨˈni.a]) is a unitary semi-presidential republic located in Southeastern Europe, bordering the Black Sea, between Bulgaria and Ukraine. It also borders Hungary, Serbia, and Moldova. It covers 238,391 square kilometres (92,043 sq mi) and has a temperate-continental climate. With its 19.94 million inhabitants, it is the seventh most populous member state of the European Union. Its capital and largest city, Bucharest, is the sixth largest city in the EU. The River Danube, which is Europe's second longest river after the Volga, rises in Germany and flows southeastwards for a distance of 2,857 km, coursing through ten countries before emptying in Romania's Danube Delta. Some of its 1,075 km length bordering the country drains the whole of it. The Carpathian Mountains, with their tallest peak Moldoveanu at 2,544 m (8,346 ft), cross Romania from the north to the southwest.

Modern Romania emerged within the territories of the ancient Roman province of Dacia, and was formed in 1859 through a personal union of the Danubian Principalities of Moldavia and Wallachia. The new state, officially named Romania since 1866, gained independence from the Ottoman Empire in 1877. At the end of World War I, Transylvania, Bukovina and Bessarabia united with the sovereign Kingdom of Romania. During World War II, Romania was an ally of Nazi Germany against the Soviet Union, fighting side by side with the Wehrmacht until 1944, then it joined the Allied powers after being occupied by the Red Army forces. During the war, Romania lost several territories, of which Northern Transylvania was regained after the war. Following the war, Romania became a socialist republic and member of the Warsaw Pact. After the 1989 Revolution, Romania began a transition back towards democracy and a capitalist market economy.

Romanian wine

Romania is one of the world's largest wine producers and sixth largest among European countries – in 2015 it produced around 4.069 million hectolitres of wine. In recent years, Romania has attracted many European business people and wine buyers, due to the affordable prices of both vineyards and wines compared to other wine producing nations such as France, Germany, and Italy.

In Romania are mainly cultivated grape varieties for white wines, the most widespread being Fetească Albă, Fetească Regală, Riesling, Aligoté, Sauvignon, Muscat, Pinot Gris, Chardonnay, Tămâioasă Românească, Grasă de Cotnari, Galbenă de Odobești. Therewith, the main grape varieties for red wines are Merlot, Cabernet Sauvignon, Băbească Neagră, Fetească Neagră, Pinot Noir, Busuioacă de Bohotin.

History

Romania has one of the oldest wine making traditions in the world, its viticulture dating back more than 6,000 years. Due to the hot dry summers, the location proved to be successful and the grape vineyards thrived. Since the medieval times, wine has been the traditional alcoholic beverage of the Romanians.
