Useful energy
Net Zero by 2050, A Roadmap for the Global Energy Sector, published by the International Energy Agency in May 2021, suggests that useful energy: ‘Refers to the energy that is available to end-users to satisfy their needs. This is also referred to as energy services demand. As result of transformation losses at the point of use, the amount of useful energy is lower than the corresponding final energy demand for most technologies. Equipment using electricity often has higher conversion efficiency than equipment using other fuels, meaning that for a unit of energy consumed electricity can provide more energy services.’
