Bistrița-Năsăud County
Bistrița-Năsăud () is a county (județ) of Romania, in Transylvania, with its capital city at Bistrița. Name In Hungarian language, Hungarian, it is known as ''Beszterce-Naszód megye'', and in German language, German as ''Kreis Bistritz-Nassod''. The name is identical with the county created in 1876, Beszterce-Naszód County ( ro, Comitatul Bistriţa-Năsăud) in the Kingdom of Hungary (the county was recreated in 1940 after the Second Vienna Award, as it became part of Hungary again). Except these, as part of Romania, until 1925 the former administrative organizations were kept when a new county system was introduced. Between 1925–1940 and 1945–1950, most of its territory belonged to the Năsăud County, with smaller parts belonging to the Mureș County, Mureș, Cluj County, Cluj, and Someș County, Someș counties.

Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units, International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Energy transformation, energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish people, Scottish invention, inventor, mechanical engineer, and chemist who improved the Newcomen steam engine, Newcomen engine with his own Watt steam engine, steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potentia ...

Thin Film Solar Cell
A thin-film solar cell is a second generation solar cell that is made by depositing one or more thin layers, or thin film (TF) of photovoltaic material on a substrate, such as glass, plastic or metal. Thin-film solar cells are commercially used in several technologies, including cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), and amorphous thin-film silicon (a-Si, TF-Si). Film thickness varies from a few nanometers ( nm) to tens of micrometers ( µm), much thinner than thin-film's rival technology, the conventional, first-generation crystalline silicon solar cell (c-Si), that uses wafers of up to 200 µm thick. This allows thin film cells to be flexible, and lower in weight. It is used in building-integrated photovoltaics and as semi-transparent, photovoltaic glazing material that can be laminated onto windows. Other commercial applications use rigid thin film solar panels (interleaved between two panes of glass) in some of the world's largest photovol ...

Adevărul
''Adevărul'' (; meaning "The Truth", formerly spelled ''Adevĕrul'') is a Romanian daily newspaper, based in Bucharest. Founded in Iași, in 1871, and reestablished in 1888, in Bucharest, it was the main left-wing press venue to be published during the Romanian Kingdom's existence, adopting an independent pro- democratic position, advocating land reform, and demanding universal suffrage. Under its successive editors Alexandru Beldiman and Constantin Mille, it became noted for its virulent criticism of King Carol I. This stance developed into a republican and socialist agenda, which made ''Adevărul'' clash with the Kingdom's authorities on several occasions. As innovative publications which set up several local and international records during the early 20th century, ''Adevărul'' and its sister daily ''Dimineața'' competed for the top position with the right-wing ''Universul'' before and throughout the interwar period. In 1920, ''Adevărul'' also began publishing its prestigious ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Power
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine. Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar electricity has fallen, grid-connected solar PV systems have grown more or less exponentially. Millions of installations and gigawatt-scale photovoltaic power stations continue to be built, with half of new generation capacity being solar in 2021. ...

Solar Inverter
A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical balance of system (BOS)–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection. Classification Solar inverters may be classified into four broad types: # Stand-alone inverters, used in stand-alone power systems where the inverter draws its DC energy from batteries charged by photovoltaic arrays. Many stand-alone inverters also incorporate integral battery chargers to replenish the battery from an AC source when available. Normally these do not interface in any way wi ...

Euro
The euro ( symbol: €; code: EUR) is the official currency of 19 out of the member states of the European Union (EU). This group of states is known as the eurozone or, officially, the euro area, and includes about 340 million citizens . The euro is divided into 100 cents. The currency is also used officially by the institutions of the European Union, by four European microstates that are not EU members, the British Overseas Territory of Akrotiri and Dhekelia, as well as unilaterally by Montenegro and Kosovo. Outside Europe, a number of special territories of EU members also use the euro as their currency. Additionally, over 200 million people worldwide use currencies pegged to the euro. As of 2013, the euro is the second-largest reserve currency as well as the second-most traded currency in the world after the United States dollar. , with more than €1.3 trillion in circulation, the euro has one of the highest combined values of banknotes and coins in c ...

Photovoltaics
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors. A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating. The mount may be fixed or use a solar tracker to follow the sun across the sky. Photovoltaic technology helps to mitigate climate change because it emits much less carbon dioxide than fossil fuels. Solar PV has specific advantages as an energy source: once installed, its operation generates no pollution and no greenhouse gas emissions, it shows scalability in respect of power needs and silicon has large availability in the Earth's crust, although other materials required in PV system m ...

Renewable Energy Commercialization
Renewable energy commercialization involves the deployment of three generations of renewable energy technologies dating back more than 100 years. First-generation technologies, which are already mature and economically competitive, include biomass, hydroelectricity, geothermal power and heat. Second-generation technologies are market-ready and are being deployed at the present time; they include solar heating, photovoltaics, wind power, solar thermal power stations, and modern forms of bioenergy. Third-generation technologies require continued R&D efforts in order to make large contributions on a global scale and include advanced biomass gasification, hot-dry-rock geothermal power, and ocean energy.International Energy Agency (2007)''Renewables in global energy supply: An IEA facts sheet'' (PDF)OECD, 34 pages. As of 2012, renewable energy accounts for about half of new nameplate electrical capacity installed and costs are continuing to fall. Public policy and political ...
