The world needs to get serious about electrification – here’s why

the gist

Only 23% of the world's final energy, the energy that actually reaches factories and homes, arrives as electricity; the rest is fuel burned directly in cars, furnaces and boilers. At the UN climate summit COP31 in Turkey, the presidency launched a '35-by-35' pledge: lift electricity to 35% of final energy use by 2035. Electrification goes beyond swapping petrol cars for electric ones: it means replacing direct burning of fossil fuels in transport, buildings and industry with electricity, increasingly renewable. Analysts argue this matters because the world will probably overshoot 1.5°C of warming for at least a decade, peaking near 1.7°C in the 2040s, and removing carbon at scale isn't yet possible.

how it works

Burning fuel in an engine or furnace loses most of its energy as waste heat, while electric motors and heat pumps convert electricity into motion or warmth far more efficiently. So shifting to electricity cuts the total energy needed, and the electricity itself can come from wind, solar and hydro instead of coal and gas.

so what

Cutting emissions faster is the only tool already available, and electrification is its biggest lever. The 35% target is a measurable benchmark governments can sign up to or be judged against.

fun fact

Electric motors are typically far more efficient than combustion engines, wasting much less energy as heat.

background

Electrification is the process of powering by electricity and, in many contexts, the introduction of such power by changing over from an earlier power source. In the context of history of technology and economic development, electrification refers to the build-out of the electricity generation and electric power distribution systems. In the context of sustainable energy, electrification refers to the build-out of super grids and smart grids with distributed energy resources (such as energy storage) to accommodate the energy transition to renewable energy and the switch of end-uses to electricity.
