In W-Europe this is between 5 and 8 MWh/a. Total consumption (2nd column) divided by number of inhabitants (last column) gives a country's consumption per head. The total consumption (including the amount consumed by the power plants) and the energy sources to generate this electricity is given per country. 90% of the consumption of all more than 190 countries. The table lists the top 37 electricity consuming countries, which use 19,000 TWh/a. In Middle East, growth rate was softened but remained high, just below 4%. 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 demand related to high economic growth. Electricity demand also dropped by more than 4.5% in CIS countries, driven by a large cut in Russian consumption. In OECD countries, accounting for 53% of the total,Įlectricity demand scaled down by more than 4.5% in both Europe and North America while it shrank by above 7% in Japan. Įxcept in Asia and Middle East, consumptions were reduced in all the world regions. Source: Enerdata Statistical Energy ReviewĪt the world level, energy consumption was cut down by 1.5% during 2009, for the first time since World War II. World electricity consumption down in 2009 Įlectricity Consumption in 2009. The study used six parameters as input data, employment, GDP, dwelling, population, heating degree day and cooling degree day, with electricity demand as output variable. The difference of 3,464 TWh (17%) was consumed in the process of generating power and lost in transmission to end users.Ī sensitivity analysis on an adaptive neuro-fuzzy network model for electric demand estimation shows that employment is the most critical factor influencing electrical consumption. Among all electricity, 1,420 TWh (4.84 quad) was used in residential area, 1,270 TWh (4.32 quad) used in commercial, 1,020 TWh (3.47 quad) used in industrial and 8.8 TWh (0.03 quad) used in transportation.ġ Quad = 1 Quadrillion BTU = 1 x 10 15 BTU = 293 TWhĭuring the year 16,816 TWh (83%) of electric energy was consumed by final users. The gross generation of electricity in that year was 4,250 TWh (14.50 quad) the difference of 7,940 TWh (27.10 quad) was conversion losses. In 2005, the primary energy used to generate electricity was 12,190 terawatt-hours (41.60 quad). This is approximately a third of the total energy consumption of 15 TW ( see world energy consumption). The primary energy consumption to generate electric power is thus in the order of 5 TW. The total primary energy used in a thermal power station to produce this power is roughly a factor 2 to 3 higher because the efficiency of electricity generation is roughly 30–50% (see also energy conversion efficiency). This number corresponds to an average power of 2.31 TW continuously during the year. In 2008, the world total of electricity production was 20.279 petawatt-hours (PWh).
#Tera term 4.84 generator
The invention of the steam turbine in 1883 to drive the electric generator started a strong increase of world electricity consumption. During operation, some part of the energy-depending on the electrical efficiency-is consumed in unintended output, such as waste heat.Įlectricity has been generated in power stations since 1882.
