Electricity accounts for about 20% of final energy use globally, with China nearing 30%, as electrification shifts from climate strategy to economic competitiveness. Global electric car sales exceeded 20 million in 2025, one in four new cars sold. The transition exposes grid constraints as demand from EVs, data centers, and industry strains networks.

Key Facts

Electricity accounts for about 20% of final energy use globally, approaching 30% in China, 22% in the US, and 21% in the EU.
Global electric car sales exceeded 20 million in 2025, with electric cars making up one in four new cars sold worldwide.
Combustion engines can waste up to 80% of fuel energy, while electric motors convert about 80% of electrical energy into motion.
Fully electrifying a typical European household's heating and transport could cut its overall energy bill by more than half, according to WRI analysis.

Electrification Shift

Clem Perry, Global Lead for Clean Energy Supply at the WRI Polsky Center, says electrification is moving beyond climate strategy to become a question of affordability, competitiveness, energy security, and resilience to volatile fossil fuel markets. The shift is visible in electric buses, heat pumps, electric vehicles, and increasingly electrified industrial processes. More economic activity is shifting from direct fossil-fuel combustion toward electricity, from transport and buildings to industrial equipment. Electrification does not necessarily mean consuming more energy; its economic logic lies partly in efficiency.

Efficiency Gains

Electric motors can convert around 80% of electrical energy into motion, while combustion engines can waste as much as 80% of the energy contained in fuel. Heat pumps can deliver several units of heat for each unit of electricity consumed. As households and businesses electrify transport and heating, electricity consumption may rise while overall energy costs can fall because electric technologies are more efficient. Avoided fossil-fuel costs can offset higher electricity costs, although the scale of savings varies by market and technology.

Grid Constraints

The transition exposes a new constraint: electricity networks. The challenge facing many economies will not only be whether they can generate enough power, but whether their grids can deliver it at the right place and at the right time. Electric vehicles, industrial facilities, data centers, cooling systems, and new housing are all adding demand to networks that in many countries are already under pressure.
