- 1Electrification could cut the world's total energy needs▼Electrification efficiency: The world will need less energy after the transition
A new analysis by researcher Hannah Ritchie argues that electrifying transport, heating and industry will make the global energy system far more efficient, so the world will need less primary energy after the clean transition. Fossil fuel combustion wastes most of its energy as heat, while electric motors, heat pumps and batteries deliver the same services with a fraction of the input, she explains.
