Electric car use by country
Electric car use by country covers how battery electric and plug-in hybrid cars are adopted in national markets, with Norway, China, and Europe leading in 2025.
Electric double-layer gating
Electric double-layer gating is a technique in which ions in an electrolyte form a nanometer-thin capacitor at a material's surface, inducing carrier densities far beyond conventional dielectrics and tuning phase transitions.
Electric energy consumption
Electric energy consumption, also called electricity consumption, is the use of electrical energy by end users, billed in kilowatthours and growing faster than total energy demand.
Electric fireplace
An electric fireplace is an appliance that simulates a wood or gas fire with a flame effect and an electric heater, producing no combustion or fumes.
Electric generator
An electric generator is a device that converts a form of energy, usually mechanical motion, into electricity, based on electromagnetic induction discovered by Michael Faraday in 1831.
Electric guitar
An electric guitar is a guitar that converts the vibration of its metal strings into an amplified electrical signal, developed in the 1920s and 1930s to be heard over big bands.
Electric heating
Electric heating is the production of heat from electricity, through resistive elements or heat pumps, used in home furnaces, baseboard heaters, water heaters, and industrial furnaces and boilers.
Electric Hydrogen Co.

Electric locomotive
An electric locomotive is a railway locomotive with electric motors that draws power from overhead wires or conductor rails, offering high power and fast acceleration.
Electric machine
An electric machine, also called electrical machinery, is an electromechanical device that converts energy between electrical and mechanical forms using magnetic fields, including motors, generators, and transformers.
Electric motor
An electric motor is a machine that converts electrical energy into mechanical energy using a magnetic field and current, ranging from appliances to industrial machines.
Electric motorcycles and scooters
Electric motorcycles and scooters are two-wheeled road vehicles driven by an electric motor and rechargeable battery, ranging from 14 kg rental e-scooters to highway-capable motorcycles.
Electric multiple unit
An electric multiple unit (EMU) is a self-propelled passenger train with motors distributed among its carriages rather than concentrated in a locomotive, common in commuter and high-speed service.
Electric power
Electric power is the rate at which electric energy is transferred, measured in watts or megawatts, and produced from sources like coal, gas, and wind.
Electric Power Development (J-POWER)
Electric Power Development Co., Ltd. (電源開発株式会社), known commercially as J-POWER, is a Japanese power generation company founded in 1952, headquartered in Tokyo, and fully privatized in 2004.
Electric power distribution
Electric power distribution is the final stage of the electricity supply chain, delivering power from distribution substations to customers at voltages from 4 kV down to 120 V.
Electric power steering
Electric power steering (EPS) is a steering system where an electric motor provides assist, replacing hydraulic pumps. It debuted in 1988 and now dominates the market.
Electric power system
An electric power system is the network that generates electricity, transmits it over long distances at high voltage, and distributes it to consumers, joined at substations.
Electric power transmission
Electric power transmission is the bulk movement of electricity from power plants to load centers over high-voltage lines, kept separate from the lower-voltage distribution system serving homes and businesses.
Electric Reliability Council of Texas
The Electric Reliability Council of Texas (ERCOT) is the independent system operator managing power for 27 million customers, about 90 percent of Texas's electric load.
Electric rickshaw
An electric rickshaw, or e-rickshaw, is a low-speed battery-powered three-wheeler carrying passengers or goods for hire, used chiefly in India, Bangladesh, and Nepal, with India the world's largest market.
Electric sail
The electric sail, or E-sail, is a propellantless spacecraft propulsion concept that uses charged tethers to extract thrust from the solar wind, proposed by Pekka Janhunen in 2004.
