Paper 3
Reducing energy use by avoiding waste or changing behaviour, such as switching off unused lights or making fewer car journeys.
Revise: Technical challengesEnergy conservation means avoiding unnecessary energy use or changing how energy is used. Switching off lights in empty rooms and turning appliances off rather than leaving them on standby both reduce demand. Efficiency changes how much energy a task requires; conservation changes whether, or how much, the task is carried out.
