AlbedoThe share of incoming sunlight that a surface reflects, on a scale from 0 (absorbs everything) to 1 (reflects everything).Anaerobic digestionA process in which microbes break down organic material such as food waste, slurry and crops without oxygen, producing biogas and a fertiliser called digestate.Balancing MechanismThe real-time market the National Energy System Operator uses to pay generators, batteries and large users to change their output so supply matches demand every second.
