The line graph demonstrates account of energy using in the USA between 1980 with planning until 2030.

It can be clearly seen that all units of energy consumption by fuel increased, except Hydropower which will remain steady from 2010 to 2030 and Natural Gas which would stop rising in 2015.

Although in 1980 there were just over 15 quadrillion units of Coal, the number of Natural Gas was 5 points higher. Despite of that 50 years later, starting in 2015 the number of coal will gradually climb to 60 per cent, whereas Natural Gas, will stay at the same point after some slight falls and growthes.

During 1980 the number of both Nuclear and Solar/Wind sources were just under 5 quadrillion units, however it had insignificantly increases and it reached around 20 per cent of total amount. In contrast ,the rate of Hydropower reached the highest point of 50 units in 2005 and after slight decrease starting by 2015 would remain stable.

Consumption of Petrol and Oil had substantial rise between 2005 to 2013, moreover it will increase till 50 quadrillion units by 2030.

To sum up consumption of Coal and Petrol/Oil in US, according to the graph will steadly increase 15 following years.
