SunShot Initiative
The SunShot Initiative is a federal government program run by the US Department of Energy's Solar Energy Technologies Office. It bills itself as a national effort to support solar energy adoption in order to make solar energy affordable for all Americans. The initiative is a collaboration of private companies, universities, state and local governments, and nonprofits, as well as national laboratories. Background The United States Department of Energy (DOE) announced its sponsorship of the SunShot Initiative in 2011 and was established as a way to; increase utility of, photovoltaic goods and services in the United States by decreasing its original costs in order to: (1)enable the competitiveness of the Solar Powered energy market, and supply chain comparatively to other energy sources, (2) increase the competitiveness of solar power energy market, (3) foster growth of research and development within the energy sector, specifically in solar energy alternatives, and (4) address the g ...

United States Department Of Energy
The United States Department of Energy (DOE) is an executive department of the U.S. federal government that oversees U.S. national energy policy and manages the research and development of nuclear power and nuclear weapons in the United States. The DOE oversees the U.S. nuclear weapons program, nuclear reactor production for the United States Navy, energy-related research, and domestic energy production and energy conservation. The DOE was created in 1977 in the aftermath of the 1973 oil crisis. It sponsors more physical science research than any other U.S. federal agency, the majority of which is conducted through its system of National Laboratories. The DOE also directs research in genomics, with the Human Genome Project originating from a DOE initiative. The department is headed by the Secretary of Energy, who reports directly to the president of the United States and is a member of the Cabinet. The current Secretary of Energy is Jennifer Granholm, who has served ... [...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 ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Solar Power In The United States
Solar power includes solar farms as well as local distributed generation, mostly on rooftops and increasingly from community solar arrays. In 2021, utility-scale solar power generated 115 terawatt-hours (TWh), or 2.8% of electricity in the United States. Total solar generation that year, including estimated small-scale photovoltaic generation, was 164 TWh. As of the end of 2021, the United States had 121 gigawatts (GW) of installed photovoltaic and concentrated solar power capacity combined. This capacity is exceeded only by China and the European Union. In 2021, 36% of all new electricity generation capacity in the country came from solar, surpassed only by wind with 41%. By 2015, solar employment had overtaken oil and gas as well as coal employment in the United States. In 2020, more than 230,000 Americans were employed in the solar industry. The United States conducted much early research in photovoltaics and concentrated solar power. It is among the top countries i ...

United States Department Of Energy National Laboratories
The United States Department of Energy National Laboratories and Technology Centers is a system of facilities and laboratories overseen by the United States Department of Energy (DOE) for scientific and technological research. Sixteen of the seventeen DOE national laboratories are federally funded research and development centers administered, managed, operated and staffed by private-sector organizations under management and operating (M&O) contract with DOE (with the National Energy Technology Laboratory being the exception). History The system of centralized national laboratories grew out of the massive scientific endeavors of World War II, in which new technologies such as radar, the computer, the proximity fuse, and the atomic bomb proved decisive for the Allied victory. Though the United States government had begun seriously investing in scientific research for national security in World War I, it was only in late 1930s and 1940s that monumental amounts of resources were ...

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. ...

Federal Government Of The United States
The federal government of the United States (U.S. federal government or U.S. government) is the national government of the United States, a federal republic located primarily in North America, composed of 50 states, a city within a federal district (the city of Washington in the District of Columbia, where most of the federal government is based), five major self-governing territories and several island possessions. The federal government, sometimes simply referred to as Washington, is composed of three distinct branches: legislative, executive, and judicial, whose powers are vested by the U.S. Constitution in the Congress, the president and the federal courts, respectively. The powers and duties of these branches are further defined by acts of Congress, including the creation of executive departments and courts inferior to the Supreme Court. Naming The full name of the republic is "United States of America". No other name appears in the Constitution, and this i ...
