Nellis Solar Power Plant
The Nellis Solar Power Plant is a 14-megawatt (MW) photovoltaic power station located within Nellis Air Force Base in Clark County, Nevada, northeast of Las Vegas. The power plant was inaugurated in a ceremony on December 17, 2007, with Nevada Governor Jim Gibbons activating its full operation. On average, it has since generated 32 gigawatt-hours of electricity annually and supplied more than 25% of the power used at the base. Occupying of land leased from the Air Force at the northeastern corner of the base, this ground-mounted solar system employs an advanced sun tracking system, designed and deployed by SunPower. The system contains approximately 70,000 solar panels, and the peak power generation capacity of the plant is approximately 13 MWAC. This means the ratio of average to peak output, or capacity factor, of this plant is around 22%. The energy generated will support more than 12,000 military and civilians at Nellis who are responsible for Air Force ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Solar Panel
A solar cell panel, solar electric panel, photo-voltaic (PV) module, PV panel or solar panel is an assembly of photovoltaic solar cells mounted in a (usually rectangular) frame, and a neatly organised collection of PV panels is called a photovoltaic system or solar array. Solar panels capture sunlight as a source of radiant energy, which is converted into electric energy in the form of direct current (DC) electricity. Arrays of a photovoltaic system can be used to generate solar electricity that supplies electrical equipment directly, or grid-connected photovoltaic system, feeds power back into an alternate current (AC) electric grid, grid via an solar inverter, inverter system. History In 1839, the ability of some materials to create an electrical charge from light exposure was first observed by the French physicist Edmond Becquerel. Though these initial solar panels were too inefficient for even simple electric devices, they were used as an instrument to measure light. ...

Renewable Energy In The United States
According to preliminary data from the US Energy Information Administration, renewable energy accounted for about 12.6% of total primary energy consumption and about 19.8% of the domestically produced electricity in the United States in 2020. Since 2019, wind power has been the largest producer of renewable electricity in the country. Wind power generated 337.9 terawatt-hours of electricity in 2020, which accounted for 8.4% of the nation's total electricity generation and 43.2% of the total renewable electricity generation. By October 2021, the United States nameplate generating capacity for wind power was 129,256 megawatts (MW). Texas remained firmly established as the leader in wind power deployment, followed by Iowa and Oklahoma as of year end 2020. Hydroelectric power is the second-largest producer of renewable electricity in the country, generating around 7.3% of the nation's total electricity in 2020 as well as 36.4% of the total renewable electricity generation. ...

List Of Photovoltaic Power Stations
The following is a list of photovoltaic power stations that are larger than 300 megawatts (MW) in current net capacity.Note that nominal power may be AC or DC, depending on the plant, and therefore any totals quoted are hybrid. SeAC-DC conundrum: Latest PV power-plant ratings follies put focus on reporting inconsistency (update) Most are individual photovoltaic power stations, but some are groups of co-located plants owned by different independent power producers and with separate transformer connections to the grid. Wiki-Solar reports total global capacity of utility-scale photovoltaic plants to be some 96 GWAC which generated 1.3% of global power by the end of 2016. The size of photovoltaic power stations has increased progressively over the last decade with frequent new capacity records. The 97 MW Sarnia Photovoltaic Power Plant went online in 2010. Huanghe Hydropower Golmud Solar Park reached 200 MW in 2012. In August 2012, Agua Caliente Solar Project in Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DeSoto Next Generation Solar Energy Center
The DeSoto Next Generation Solar Energy Center is a photovoltaic power station in Arcadia, DeSoto County, in the U.S. state of Florida, owned by Florida Power & Light (FPL). President Barack Obama attended the plant's commissioning on October 27, 2009. It has a nameplate capacity of 25 megawatts (MW), and produces an estimated 42,000 megawatt hours (MW·h) of electricity per year (an average output of about 4.8 MW). The plant cost $150 million to construct. The plant consists of over 90,000 SunPower solar panels with single-axis trackers on . FPL has to get a permit for construction of the second stage and had filed for the permit to build the third stage of the plant. At the second stage, 49 MW of capacity will be added. At the third stage, 226 MW of capacity is planned to be added bringing the total capacity of the plant up to 300 MW. Production See also * Solar power in the United States Solar power includes s ...

Energy Information Administration
The U.S. Energy Information Administration (EIA) is a principal agency of the U.S. Federal Statistical System responsible for collecting, analyzing, and disseminating energy information to promote sound policymaking, efficient markets, and public understanding of energy and its interaction with the economy and the environment. EIA programs cover data on coal, petroleum, natural gas, electric, renewable and nuclear energy. EIA is part of the U.S. Department of Energy. Background The Department of Energy Organization Act of 1977 established EIA as the primary federal government authority on energy statistics and analysis, building upon systems and organizations first established in 1974 following the oil market disruption of 1973. EIA conducts a comprehensive data collection program that covers the full spectrum of energy sources, end uses, and energy flows; generates short- and long-term domestic and international energy projections; and performs informative energy analyses. ...

MW·h
A kilowatt-hour (unit symbol: kW⋅h or kW h; commonly written as kWh) is a unit of energy: one kilowatt of power for one hour. In terms of SI derived units with special names, it equals 3.6 megajoules (MJ). Kilowatt-hours are a common billing unit for electrical energy delivered to consumers by electric utilities. Definition The kilowatt-hour is a composite unit of energy equal to one kilowatt (kW) sustained for (multiplied by) one hour. Expressed in the standard unit of energy in the International System of Units (SI), the joule (symbol J), it is equal to 3,600 kilojoules or 3.6 MJ."Half-high dots or spaces are used to express a derived unit formed from two or more other units by multiplication.", Barry N. Taylor. (2001 ed.''The International System of Units.'' (Special publication 330). Gaithersburg, MD: National Institute of Standards and Technology. 20.
