Another comparison... The line graph illustrates datas of energy consumption in the USA by different type of fuels from 1980 to 2030, a period of 50 years. Overall, consumption of Petrol and Oil raised and will rise in the whole period, the Coal and Natural Gas energies had a gradual rise, and will increase wildly for the next 14 years. Whereas, the Nuclear, Solar/Wind and Hydropower energies, there had no considerable increase. In 1980 the most fuel consumed was Petrol and Oil, being used up 35 quadrillion units per year. This was far higher than Coal and Natural Gas which were consumed just over 15 quadrillion units and 20 quadrillion units respectively. For the group of the Nuclear, Solar/Wind and Hydropower energies, which were less used up than the last group mentioned, it had between an insignificant minority (around 2.5 quadrillion units) to just under 10 quadrillion units. However, a part of a fluctuation from 1982 to 1995, the consumption of Petrol and Oil increased gradually, and will have raised over the period. In contrast to this, citizens of USA consumed the last group of energy at much lower units than Petrol and Oil and more especially, from the Coal and Natural Gas energies. In 1980, Nuclear, Solar/Wind energies started at the same units of consumption around 5 quadrillion units however, in 2015, established a value, which will be steady over the period.
