The document discusses how water dispenser savers called ELIMINATAs can save money, energy, and reduce carbon emissions by automatically turning off a water dispenser each night for 11 hours using a light detector, and then turning it back on in the morning. This cuts costs by £150 over 3 years while reducing carbon emissions by 216kg, by removing the 100 watts of power the dispenser uses each night when not in use. The ELIMINATAs require no setup and simply plug into the dispenser and mains power.
