Explanation:
Electric energy consumptionis the form ofenergy consumptionthat useselectric energy. Electric energy consumption is the actual energy demand made on existing electricity supply.OverviewConsumption of electric energy is measuredin watt-time, or precisely multiples of watt-hours (writtenW·h, equal towattsx hours) which is the universal measure of Energy,1 W.h [Watt hour] = 60 Wm [Watt minute]1 W.m = 60 W.s [Watt second]so,1 W.h = 60 x 60 W.s = 3600 W.s = 3.6 kWs (kilo Watt second)1 W.s = 1 JouleHence, 1 W.h = 3600 Ws = 3600 JouleAlso,1 W.h = 0.860 kcal (one food calorie Cal= 1 kcal not to be confused with a gram calorie cal)1 kWh = 860 kcal1 W·h = 3600 Watt second = 3600joule= 0.860 kcal (calorie).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 theelectrical 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 20,279terawatt-hours(TWh) or 20.279petawatt-hours(PWh). This number corresponds to an average rate of around 2.3 terawatts 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 ofgenerating electricityis 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 (seeworld energy consumption).In 2005, the primary energy used to generate electricity was 41.60 Quadrillion BTU [12, 192 TWh] (Coal 21.01 quads [6,157 TWh], Natural Gas 6.69 quads [1,960 TWh], Petroleum 1.32 quads [387 TWh], Nuclear electric power 8.13 quads [2,383 TWh], Renewable energy 4.23 quads[1,240 TWh] respectively). The gross generation of electricity in that year was 14.50 Quads [4,250 TWh]; the difference, 27.10 Quads [7,942 TWh], was conversion losses. Among all electricity, 4.84 Quads [1,418 TWh] was used in residential area, 4.32 Quads [1,266 TWh] used in commercial, 3.47 Quads [1,017 TWh] used in industrial and 0.03 Quads [8.79 TWh] used in transportation.1 Quad= 1 Quadrillion BTU = 1 x 1015BTU=293 TWh
