Energy superpower
An energy superpower is a country that supplies large amounts of energy resources (crude oil, natural gas, coal, etc.) to a significant number of other countries - and therefore has the potential to influence world markets for political or economic gains. Energy superpower status might be exercised, for example, by…
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…
Photovoltaic system
A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the…
Distributed generation
Distributed generation, also distributed energy, on-site generation (OSG), or district/decentralized energy, is electrical generation and storage performed by a variety of small, grid-connected or distribution system-connected devices referred to as distributed energy resources (DER). Conventional power stations, such…
Concentrated solar power
Concentrated solar power (CSP), also called concentrating solar power or concentrated solar thermal, involves systems that collect solar heat for multiple purposes like cooking, desalination, or the generation of electric solar power, by using mirrors to concentrate a large area of sunlight toward a receiver. …
Economy 7
Economy 7 is a differential tariff provided by United Kingdom electricity suppliers that uses base load generation to provide cheap off-peak electricity during the night. Houses using the Economy 7 tariff require a special electricity meter which provides two different readings - one for electricity used during the…
Energiewende
The Energiewende (German for 'energy turnaround') (pronounced [ʔenɐˈɡiːˌvɛndə] ) is the ongoing energy transition by Germany. The new system intends to rely heavily on renewable energy (particularly wind, photovoltaics, and hydroelectricity), energy efficiency, and energy demand management.
Energy engineering
Energy engineering is a multidisciplinary field of engineering that focuses on optimizing energy systems, developing renewable energy technologies, and improving energy efficiency to meet the world's growing demand for energy in a sustainable manner. It encompasses areas such as energy harvesting and storage, energy…
Energy transition
An energy transition (or energy system transformation) is a major structural change to energy supply and consumption in an energy system. Currently, a transition to sustainable energy is underway to limit climate change.
