电
a source of power used for lighting, heating, and operating machines
Electricity is a form of energy that flows through wires and powers devices like lights, computers, and appliances. It is produced in power plants by converting other types of energy, such as burning coal, using wind, or harnessing sunlight. Electricity can be stored in batteries or used immediately when needed. It is essential for modern life and is used in homes, businesses, and factories. Although it is a very convenient energy source, producing electricity can sometimes cause pollution, especially when fossil fuels are used. Efforts are being made to use cleaner sources of electricity.
