The pie charts compare the shares of energy production through distinct sources – oil, nuclear, hydrogen, coal, natural gas, and other renewable sources – in a state in 1985 and 2003.
Overall, as is evident from the charts, oil was a leader in terms of energy production in both years. The rates of hydrogen usage for the production of energy showed no change.
At the outset with 1985, oil constituted half of the energy production and took the first place, accounting for 52%. Nuclear utilization constituted 22% of energy manufacture, highlighting a 30% marginal difference in contrast to oil. Coal and hydrogen were among the least utilized sources; the former and latter showed 8% and 4%, respectively. Natural gas was roughly three times higher than hydrogen, illustrating 13% with a 9% marginal distinction.
As for 2003, variation is obvious compared to the former year. Natural gas exhibited 23%, a 10% increase in contrast to 1985. Conversely, oil and nuclear usage for energy production experienced a depletion, accounting for 39% and 17%, in turn. The figure of nuclear sources constituted 17% of energy production. Strikingly, the percentages pertaining to coal saw no change, remaining only 4% in both years.
