The graph illustrates the data from an Annual energy outlook regarding the daily consumption of six different energies in the USA for the fifty year period from the year 1980 to 2030. The energy consumption is measured in quadrillion units.
Overall, petrol and oil was the most consumed fuel across the time period. The least consumed fuel is the hydropower. While the natural gas, coal, and nuclear was experiencing an increasing usage across the time period, the other two fuels nuclear, solar and hydropower showed a little variation in the usage.
In terms of consumption of petrol and oil, it recorded about 35 quadrillion units in 1980, following which a slight dip in the consumption was observed. The daily usage of the fuel fell by 5 quadrillion units compared to starting year. A marked increase was evident after the year 2000, reaching its peak of about 50 quadrillion units in 2030.
An moderate increase in the consumption rates was visible in the case of natural gas and coal, which ranged from approximately 15 and 20 quadrillion units respectively in 1990 to about 27 and 30 quadrillion units in 2030.
A similar trend was observed in the nuclear power, which saw a noticeable growth in its consumption from about 4 in 1990 to 10 quadrillion units in 2030. The solar and wind power saw a negligible change in the consumption rate over the 50 year period. The solar power ranged from 4 quadrillion units to 6 quadrillion units, whereas the hydropower experienced a minute dip from 4 to 3 quadrillion units over the 50 year interval.
