Electrification is generally referred to as the provision of infrastructure in the form of power grids to supply a region or country with electrical energy. As a key feature, large-scale electrification enables spatial separation between the energy consumer, such as an electric drive or lighting, and the power plant, where various primary energy sources are...

Electrical Engineering is an  engineering science that deals with research and development, as well as production, assembly and maintenance of electrical equipment and electrical equipment . This includes, for example, electrical machines and components,  circuits for the control, measurement, and computer technology or the technical informatics, electrical installation and power engineering. Electrical engineering also lays the foundation for the  digitization, which is the basis for technological development. The demand for electrical engineers is correspondingly high. Apprenticeships in electrical...

Energy efficiency generally describes the ratio of a certain benefit – for example, the provision of light or heat – to its energy input. The less energy used to manufacture or operate a product, the more energy-efficient and environmentally friendly it is. In the case of technical equipment, energy efficiency classes assist in the selection...

An energy community is an association of at least two, but usually several participants, in order to be able to both jointly produce and use energy in the form of electricity, heat and biogas. Members of this community can produce, store, sell, and consume energy across property lines. Such energy communities are also driving the...

Energy-intensive products are those whose production or operation requires above-average amounts of energy. The term comes from the noun energy intensity. Among other things, this is also an economic indicator of energy efficiency. Here, the energy consumption of an economy is set in relation to its production output and its overall energy efficiency. It is...

In a closed system, an energy source is the element that provides energy by conversion from another form of energy. It is used to generate useful energy, such as electricity, heating or energy needed to drive. Energy sources can be divided into fossil, nuclear and renewable. The most important source of energy on earth is...

Energy transition refers to the change from non-sustainable, fossil energy sources such as oil, natural gas and coal as well as nuclear energy to a sustainable energy supply using renewable energies from wind, water and sun. The aim is to create an alternative, clean, affordable and safe way to generate and use energy. The goal...

Energy industry refers to the branch of industry dealing with the production, processing and distribution of energy. These include town gas, natural gas, liquid fuels, electrical energy, district heating, oil and solid energy sources such as coal, coke, peat and wood. The electricity market is a particularly important energy market. Energy quantities that are generated...
