The chart displays three kinds of fuel’s level of production from 1981 to 2000 in the UK.
Overall, there was an upward trend for petroleum and natural gas. Coal, though started as the second highest used source of energy in 1981, ended as the lowest kind of fuel being used in 2000, while the highest point of the graph belonged to petroleum.
As can be seen from the table, petroleum has a, though fluctuating, rise. The year 1981 witnessed the energy from around 90 million tons of oil being manufactured from petroleum, climbing up to the level of 140 units until 1986. In the next 5 years, the energy being generated dropped to 100 units, then gradually increased to 60 units in 2000. Natural gas maintained an upward trajectory, though is the lowest source of energy being used, only 40 units, but steadily climbed up to 100 units in 2000, and ended as the second highest used energy source.
The production levels of coal were double the level of natural gas in 1981. The United Kingdom used around 80 units of energy generated from coal in the beginning, but had a sudden drop around 1983. In the next 2 years, it had climbed up a little, but gradually decreased over the next 14 years, hit the lowest point of only almost 40% in 2000.
