The line graph from a 2011 report compares the usage of energy in the UK from 1978 to 2038 with projections.
Overall, the largest amount of fuel to produce energy throughout the entire period is petrol and oil, while the opposite is true for hydropower.
In 1978, energy consumption was mainly produced by petrol and oil, with 35 quadrillion units, which is 15 and 19 quadrillion units higher than coal and natural gas, respectively.
After 25 years, the amount of petrol and fail using for energy consumption increased significantly to 40 quadrillion, although there were fluctuations in the way. The amount of both coal and natural gas increased moderately by 4 and 3 quadrillion, respectively. Until 2038, petrol and oil, as well as coal, witnessed a permanent and noticeable growth to almost 50 and 30, respectively, while the amount of natural gas rose to 25 quadrillion until 2018 and remained stable until the end of the period.
In the beginning year of the graph, the quantity of nuclear, hydropower, solar, and wind power stood at the same amount. The amount of nuclear energy used for production increased slightly and steadily until 2003, whilst the amounts of both hydropower and solar and wind fluctuated and reached 3 and almost 5 quadrillion, respectively. Until 2038, the usage of nuclear power will increase slightly to around 7 quadrillion units, despite remaining stable before. The quantity of both hydropower, solar, and wind fluctuated until 2013, and then the amount of solar and wind will increase unnoticeably to 6, whereas the quantity of hydropower will remain unchanged until 2038.
