Odessa

Odessa or Odesa (Ukrainian: Оде́са, [oˈdɛsɐ]; Russian: Оде́сса; IPA: [ɐˈdʲesə]) is a city in Ukraine and a major seaport and transportation hub located on the northwestern shore of the Black Sea. Odessa is also an administrative center of the Odessa Oblast and a multiethnic major cultural center. Odessa is the third biggest city in Ukraine and known in Ukraine as Black Sea Pearl or Southern Palmyra.

The predecessor of Odessa, a small Tatar settlement, was founded by Hacı I Giray, the Khan of Crimea, in 1440 and originally named after him as "Hacıbey". After a period of Lithuanian control, it passed into the domain of the Ottoman Sultan in 1529 and remained in Ottoman hands until the Ottoman Empire's defeat in the Russo-Turkish War of 1792.

In 1794, the city of Odessa was founded by a decree of the Empress Catherine the Great. From 1819 to 1858, Odessa was a free port. During the Soviet period it was the most important port of trade in the Soviet Union and a Soviet naval base. On 1 January 2000, the Quarantine Pier at Odessa Commercial Sea Port was declared a free port and free economic zone for a period of 25 years.

Energy

In physics, energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed. The "ability of a system to perform work" is a common description, but it is difficult to give one single comprehensive definition of energy because of its many forms. For instance, in SI units, energy is measured in joules, and one joule is defined "mechanically", being the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton. However, there are many other definitions of energy, depending on the context, such as thermal energy, radiant energy, electromagnetic, nuclear, etc., where definitions are derived that are the most convenient.

Common energy forms include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature. All of the many forms of energy are convertible to other kinds of energy, and obey the law of conservation of energy which says that energy can be neither created nor be destroyed; however, it can change from one form to another.

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.
