The line graph provides data from a 2008 report about usage of energy in the United States of America from 1980 with predictions up to 2030, measured in quadrillion units.
Overall, it is clear that America mostly relied on fossil fuels, which will continue in the future. Petrol and Oil was the highest amount in used, while hydropower was the least amount.
First of all, petrol and oil stood at 36 quadrillion units in 1980, which fluctuated over the period. In 1986, It saw a slight drop to just over 30 quadrillion units; however, that amount increased significantly in 2005 to nearly 40 quadrillion units. In 2030, it will be witness significant growth to around 50 quadrillion units. Coal and Natural Gas have also experienced dramatic fluctuations during the time span. From 1986 to 1990, these two sources of energy was identical more than 15 quadrillion units, but these two fossil fuels increased substantially to over 20 quadrillion units in 2000. Moreover, in 2030, Coal will rise sharply to nearly 30, and Natural Gas will grow considerably to less than 25 quadrillion units.
On the contrary, Nuclear and solar/wind have seen moderate fluctuations from 1980 to 2030. These renewable energy sources was similar in 1985 to approximately 4 quadrillion units; however, these sources of energy increased slightly to just over 5 quadrillion in 2005, respectively. In 2030, there will be a slight increased up to 5 quadrillion units. Finally, hydropower started at less than 5 quadrillion units, and that amount will be remain constant until 2030.
