Energy Consumption Essay

Energy Consumption Essay-61
The total consumption (including the amount consumed by the power plants) and the energy sources to generate this electricity is given per country. Total consumption (2nd column) divided by number of inhabitants (last column) gives a country's consumption per head. (1 MWh equals 1000 k Wh.) In Scandinavia, USA, Canada, Taiwan and South Korea it is much more, in developing countries much less. A very low consumption per head, as in Indonesia, means that many inhabitants are not connected to the electricity grid, and this is the reason that the world's 7th and 8th most populous countries—Nigeria (177M) and Bangladesh (156M)—do not appear in the table.From 2012 to 2014 worldwide electricity consumption increased 5%.Productivity per Electricity generation (concept similar to Energy intensity) can be measured by dividing GDP amount by the electricity generated. Electricity generation include Final consumption, in process consumption, and losses.

Many new nuclear plants will be constructed, mainly to replace old ones.

The nuclear part of electricity generation will increase from 11 to 12%. The IEA warns that in order to restrict global warming to 2 °C, the carbon dioxide emission sees world electricity consumption increasing to more than 40,000 TWh/a in 2040.

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.

Listed countries are top 20 populous countries and/or top 20 GDP (PPP) countries and Saudi Arabia as of CIA World Factbook 2009.

30 countries (exclude EU/IEA) in this table represent 77% of world population, 84% of world GDP, 83% of world electricity generation.

In Middle East, growth rate was softened but remained high, just below 4%.

The table lists the top 37 electricity consuming countries, which use 19,000 TWh/a. 90% of the consumption of all more than 190 countries.

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.
