The line graph provides information about a 2008 report about consumption of energy in the USA since 1980 with projections until 2030. In general, it can be seen from the graph that the trends will probably be different.
Wr can see the number of energy in petrol and oil increased sharply from almost 35 quadrillion unities in 1980 to 42 quadrillion unities in 2005 and it will grow rapidly between 44 quadrillion unities in 2010 to 50 quadrillion unities in 2030. However, the unities of energy in coal climbed gradually from 16 quadrillion in 1980 to 23 quadrillion in 2008. After the estimations it will rise slowly between 24 quadrillion in 2010 and approximately 30 quadrillion in 2030. Furthermore, natural gas unities of energy consumption fluctuated about almost 20 quadrillion unities in 1980 to nearly 25 quadrillion in 2008.
On the other hand, the unities of nuclear and solar energy was increased slowly from almost 4 quadrillion unities in 1980 to less than 10 quadrillion unities in 2008 but in 2010 it will remain unchange over the period of next 20 years. In addition, the hydropower unities of energy consumption was vary from 3 quadrillion unities in 1980 to 5 quadrillion in 2005. After the period the unities of Consumption will decrease and remain same from 2 quadrillion in 2009 to 2030.
