the line graph shows the generating steps of the energy resource in last 19 years from 1981 until 2000 in British. Overall, the petrol was the highest product, while natural gas and coal were the lowest expenditure in the using of energy fossil fuel.
In the 1981, natural gas manufacture started from 40 units, afterwards its gradually increased in 1994 around nearly 80 units and kept growth until reach the peak at 100 units in 2000.
Coal were produced 80 units in 1981; however, in next 3 years, the coal production plummeted in 40 units. Subsequently, in 1986 the mining of coal rose into approximately 60 units, which the rest of manufacture of coal remained steady until 1989; furthermore, the coal trends dived similarly in 1984 and kept unchanged until 2000.
Ultimately, the outcome of the petrol has become the most popular energy source in Britain with the production began from 90 units and it increased in 140 units in 1984, which was steady until 1987. however, in 1990 the coal dramatically go down around 90 units production and then it rose again into 140
unit for the 10 years .
