Knowra Energy industry Energy industry The energy industry produces, transforms, distributes, and sells fuels, electricity, and heat. It includes resource extraction, power generation, energy networks, and retail markets.
Primary energy : Energy in natural resources before conversion into usable fuels, electricity, or heat. It is the industry's raw energy input, from sunlight and wind to coal and uranium.
Electric grid : An interconnected system of power lines, substations, and control equipment that moves electricity. Grid operators balance generation and demand across the industry's electricity networks.
Renewable energy : Energy derived from sources replenished naturally on human timescales, including sunlight, wind, and water. Renewables are a growing source of electricity and heat supplied by the industry.
Greenhouse gas emissions : Gases released into the atmosphere that trap heat, including carbon dioxide and methane. Fossil fuel production and combustion are major sources of these emissions.
Vertically integrated utility : An electric utility that owns multiple stages of the electricity supply chain, often generation and networks. It contrasts with markets that separate generation from transmission and retail.
Energy conversion : The transformation of energy from one form into another, such as fuel into electricity. Conversion turns extracted resources and renewable flows into products customers can use.
Electricity market : A system for trading electricity through wholesale and retail transactions under market rules. Prices coordinate power production, network constraints, and consumption.
Nuclear power : Electricity generated using heat from controlled nuclear fission. It provides low-carbon electricity through a distinct fuel cycle and plant technology.
Energy security : The reliable availability of energy at affordable prices, despite disruptions and risks. Import dependence, infrastructure resilience, and fuel diversity affect security.
Energy liberalization : The introduction of competition and private participation into energy markets previously dominated by monopolies. Liberalization reorganizes how energy companies compete and how customers choose suppliers.
