An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire (likely copper) wound into a coil. A current through the wire creates a magnetic field which is concentrated along the center of the coil. The magnetic field disappears when the current is turned off.
With demand from data centers powering artificial intelligence and cryptocurrency operations, alongside rising electricity use in homes and businesses for heating and transportation, the EIA projects total power consumption will hit 4,179 billion kilowatt-hours (kWh) in 2025 and 4,239 billion kWh in 2026—both surpassing the current record of ...
This is a list of countries by electric energy consumption. China is the largest producer and consumer of electricity, representing 55% of consumption in Asia and 31% of the world in 2023. China is the largest producer and consumer of electricity, representing 55% of consumption in Asia and 31% of the world in 2023.
The average electric power consumption of a household in the United States is about 1 kilowatt. [ ii ] A surface area of 1 square meter on Earth receives typically about one kilowatt of sunlight from the Sun (the solar irradiance ) (on a clear day at midday, close to the equator).
Electricity consumption data in this section is based upon data mined from US DOE Energy Information Administration/Electric Power Annual 2022 files [30] In 2022 the total US consumption of electricity was 4,271.88 terawatt-hours (TWh). Consumption was up from 2021, by 122.87 TWh or +2.96%. This is broken down as:
Electric grid consumption in the US was 3,806 TWh in 2021. Since 2010, total consumption has remained within 2% of this figure. Per capita consumption was 11.5 MWh in 2021, down 8% from its peak in 2007. [85] [86] Residential customers used 39% of total electricity. [85]

Electric power, produced from central generating stations and distributed over an electrical transmission grid, is widely used in industrial, commercial, and consumer applications. A country's per capita electric power consumption correlates with its industrial development.
