The provided graph illustrates information from a 2008 report concerning use of energy in the USA in a period of 50 years with predictions.
Overall, the results fluctuated in all the six types of energies. Petrol and Oil dominated the survey in 2030, whereas the least unit was registered by hydropower and solar/wind at about 3 unit.
Firstly, petrol and oil registered 35 units, which was the highest units among energies in 1980. It fluctuated until 1995 and slightly increased during of 20 years. There is likely to be a slow rise in units over the next 15 years. The amount of consumption of natural gas and coal was 15 and 20 respectively in the beginning of the period. There was a marginally increase in coal in the next following years before the used of coal excedeed the consumption of natural gas in 2015. Coal consumption is projected to reach a peak in 2030 and natural gas will remained steadily after the year 2015.
Secondly, nuclear, solar/wind and hydropower recorded the same units(4) in 1980. Over the next 35 years nuclear and solar/wind gradually grow. There was a slightly decrease in the unit of hydropower till 2015. It is predicted, that in the 2030 nuclear, solar/wind and hydropower consumption will be around 6, 5 and 3 units respectively.
