Electric energy consumption is the form of energy consumption that uses electric energy. Electric energy consumption is the actual energy demand made on existing electricity supply. The total electricity consumption in 2012 was 20,900 TWh.Electric energy is most often measured either in joules (J), or in watt hours (W·h) representing a constant power over a period of time.
1 W·s = 1 J1 W·h = 3600 W·s = 3600 J
Electric and electronic devices consume electric energy to generate desired output (i.e., light, heat, motion, etc.). During operation, some part of the energy—depending on the electrical efficiency—is consumed in unintended output, such as waste heat.
Electricity has been generated in power stations since 1882.[2] The invention of the steam turbine in 1883 to drive the electric generator started a strong increase of world electricity consumption.
In 2008, the world total of electricity production was 20.279 petawatt-hours (PWh). This number corresponds to an average power of 2.31 TW continuously during the year. The total energy needed to produce this power is roughly a factor 2 to 3 higher because a power plant's efficiency of generating electricity is roughly 30–50%. The generated power is thus in the order of 5 TW. This is approximately a third of the total energy consumption of 15 TW (see world energy consumption).
