Electric energy consumption is the form of energy consumption that uses electric energy.
-------------------------------------------------
Overview
Consumption of electric energy is measured by W·h (Watt x Hour):^).
1 W·h = 3600 joule = 859.8 calorie energy in one year. Electric/Electronics devices consume electric energy to generate desired output(i.e. light, heat, kinetic etc.), while its operation some part of energy are consumed in unintended output. see Electrical efficiency
In 2008, world total of electricity production and consumption was 20261TWh. This number corresponds to a "consumed" power of around 2.3 TW on average. The total energy needed for producing this power is roughly a factor 2 to 3 higher because the efficiency of power plants is roughly 30-50%, see Electricity generation. 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.
16816TWh(83%) of electric energy was consumed by final users. The difference of 3464TWh(17%)was consumed in the process of generating power and consumed as transmission loss.

Electricity Consumption in 2009 Enerdata Statistical Energy Review.
At the world level, energy consumption was cut down by 1.5% during 2009, for the first time since World War II.[1] Except in Asia and Middle East, consumptions were reduced in all the world regions. In OECD countries, accounting for 53% of the total, electricity demand scaled down by more than 4.5% in both Europe and North America while it shrank by above 7% in Japan. Electricity demand also dropped by more than 4.5% in CIS countries, driven by a large cut in Russian consumption. Conversely, in China and India (22% of the world's consumption), electricity consumption continued to rise at a strong pace (+6-7%) to meet energy needs related to high economic growth. In Middle
