Energy leaks
Name(s):
Electricity losses
Energy inefficiency
Unused energy saving
Nature
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.
Incidence
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%.
