Energy leaks

Other Names:
Electricity losses
Losses in electrical systems
Unused energy saving

Energy losses occur at all levels of the energy production cycle. For example coal energy is lost as coal dust, through inefficient combustion, through wasted heat dispersed up a chimney or in cooling water, through electricity leakage along transmission lines, through inefficient electrical appliances, such as radiators.


The energy efficiency of personal mobility is around 2% for private cars. In other words, 98% of the fuel used for a trip is consumed incidental to moving the person from A to B -- a huge 80% is transformed into heat in the internal combustion engine. The current energy efficiency of lighting is around 8% and for cooking and hot water around 4%.
