electrification

Electrification is the process of powering activities and sectors by electrical energy, typically produced at central or distributed generation facilities and delivered through transmission and distribution networks. It encompasses expanding access to electricity, converting energy services from fossil fuels to electricity, and integrating electrical devices and infrastructure into daily life and industry. Historically, electrification began with the commercialization of electric power in the late 19th century, followed by rapid expansion of power grids and urban electrification; rural electrification programs in the 20th century aimed to supply remote communities.

Key components include generation, transmission, distribution, and end-use technologies. Generation can be fossil, hydro, nuclear, or renewable. Transmission lines move high-voltage power across distances; distribution networks deliver electricity to customers. Electrification also includes electrified transport (electric cars, buses, rail), electric heating (heat pumps, electric boilers), and electric industrial processes (electric arc furnaces). Increasingly, electrification relies on smart grids and microgrids, energy storage, and demand management to balance supply and demand, particularly when high shares of intermittent renewables are involved.

Benefits include reductions in local air pollution and greenhouse gas emissions when powered by low-emission sources, greater energy efficiency, and opportunities for economic development and resilience. Challenges include the high capital costs of grid expansion, the need for grid modernization, ensuring reliability and affordability, and addressing social equity. Policy often focuses on universal electrification access, decarbonizing electricity supply, and setting targets for vehicles, heating, and industry to shift to electric power.
