One litre of used cooking oil equals how much energy?

According to the CIEH (Chartered Institute of Environmental Health), it is estimated that 170,000 tonnes of FOG (Fats, Oils and Grease) is emptied into the UK's sewage system every year.^†

One litre of used cooking oil can generate enough electricity to make 240 cups of tea (i.e. 4.5 kWh)

4.5 kWh is equivalent to:

• Using a toaster for three hours, which is the same as using a toaster 60 times at 3 minutes (for a toaster that uses 1.5kW, and takes 3 minutes to toast)
• Running a dishwasher for 3 hours (for an A rated dishwasher that uses 1kW)
• Run a washing machine at 40C for 8 cycles (for a very efficient A rated machine which needs 0.56kWh per cycle at 40C)
• Switch on an old-fashioned 100W light bulb for 45 hours - or a new energy saving light bulb which gives you the same amount of light (using only 20 Watts) for 225 hours!
• Have just one 30 minute shower with a 9 kW electric shower
