<P> Next, processing of produced energy, for instance crude oil, to make it suitable for consumption by end users is described . So the supply chain between production and final consumption involves many conversion activities and much trade and transport among countries, causing a loss of one third of energy before it is consumed . </P> <P> Then lists of countries / regions are shown where most energy is consumed, distinguishing fuel and electricity . In N - America energy used per person is very high and in developing regions the percentage of renewable energy is quite high compared with world average value . </P> <P> Institutions such as the International Energy Agency (IEA) and the U.S. Energy Information Administration (EIA) collect, analyze and publish comprehensive energy data periodically . These data are used in the country lists below . </P> <P> Worldwide carbon dioxide emission from fuel combustion was 32 gigaton in 2015 . In view of contemporary energy policy of countries the IEA expects that the worldwide energy consumption in 2040 will have increased 30% and that the goal, set in the Paris Agreement about Climate Change, will not nearly be reached . A major reallocation of investment capital in the energy sector is required . </P>
