A photocopier left on overnight may waste enough energy to produce over 1,500 copies.
PC monitor energy consumption
Leaving a PC monitor on all night wastes enough energy to microwave six dinners.
AAA Batteries
A typical alkaline AAA battery stores about 1.5 watt hours: enough energy to power a 12 lumen LED bulb (typical bike light) for about 3 hours.
Hot water
Between 15 and 30 percent of the energy used by hot water tanks goes to keeping a tank of water hot, just in case you need it.
TV energy consumption
An old television in standby mode can use up to half of the electricity as it does when switched on.
Microwave energy consumption
Switching off (or unplugging) a microwave when not in use can save up to 80 kg of co2 per year.
Compressed air energy
A compressed air leak the size of a match head can waste enough energy in a working day to toast 444 slices of bread.
Lightning energy
One thunderstorm can discharge enough energy to supply the entire US with electricity for 20 minutes.
Public biogas
Three London sewage works use anaerobic digestion to decompose the sewage of 6 million people. The biogas produced (equivalent to 250,000 gallons of petrol per day) is used to heat the incoming sewage for faster treatment.
