Electrification efficiency: The world will need less energy after the transition
2 hours ago
- Electrification of energy systems eliminates large inefficiencies, reducing final energy demand by about 40% compared to current levels.
- Transport sees major efficiency gains: electric vehicles are ~4 times more efficient than petrol, with cars/vans using one-quarter of current energy.
- Buildings can be nearly fully electrified via heat pumps, achieving massive efficiency gains, especially in space and water heating.
- Industrial electrification is limited: high-temperature processes need hydrogen, while low-temperature and drying processes can use electric boilers or heat pumps.
- The analysis likely underestimates savings because it ignores other efficiency measures (e.g., insulation) and uses final energy, not primary energy.
- Overall, the transition shifts final energy from 75% fuels to 75% electricity, with hydrogen for non-electrifiable sectors.
