Electricity production. Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current. [63]
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current. [2] Concentrated solar power systems use lenses or mirrors and solar ...
Renewable energy (or green energy) is energy from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power and hydropower. Bioenergy and geothermal power are also significant in some countries. Some also consider nuclear power a renewable power source ...
Renewable energy debate. Global public support for energy sources, based on a survey by Ipsos (2011). [1] The 5 GW Rampart Dam was terminated as a result of concerns about indigenous people and ecological conservation issues. Policy makers often debate the constraints and opportunities of renewable energy .
A rooftop solar power system, or rooftop PV system, is a photovoltaic (PV) system that has its electricity -generating solar panels mounted on the rooftop of a residential or commercial building or structure. [1] The various components of such a system include photovoltaic modules, mounting systems, cables, solar inverters and other electrical ...
Solar panel – (also solar module, photovoltaic module or photovoltaic panel) is a packaged, connected assembly of photovoltaic cells. Thin film solar cell – made by depositing one or more thin layers of photovoltaic material onto a thin substrate. Polymer solar cell – are a type of flexible solar cell.
The nuclear power debate is a long-running controversy about the risks and benefits of using nuclear reactors to generate electricity for civilian purposes. The debate about nuclear power peaked during the 1970s and 1980s, as more and more reactors were built and came online, and "reached an intensity unprecedented in the history of technology controversies" in some countries.
Dye-sensitized solar cell. A selection of dye-sensitized solar cells. A dye-sensitized solar cell ( DSSC, DSC, DYSC [1] or Grätzel cell) is a low-cost solar cell belonging to the group of thin film solar cells. [2] It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system.
