The surge of Industrial Revolution, brought with it the dire need of finding effective ways to harness the fuel resources present in the UK. The UK had then resolved to explore and draw out energy from three major kinds of fuel: Petroleum, Coal and Natural Gas.
Petroleum could sustain its dominance in the fuel market, as it was produced almost double the amount of other fuels, ranging from 90 to 145 energy units, for almost two decades: 1981 and onwards. Its production levels were at its peak during the 1984-1986, then fluctuated to its trough decreasing almost 40 energy units during the year 1990. However, they rose again from the year 1995 and are increasing at a steady but slow pace.
The coal reserves of the country appear to slowly exhaust, starting at 80 energy units in the year 1981 and dropping at a sharp 40 energy units in a span of three years. Then onwards after its recovery back to 60 energy units in 1981, the production levels are roughly declining linearly, and are standing at 36 energy units in year 2000.
UK is growing increasingly familiar with new means to harness the untapped Natural Gas present in its territory. From its uniform trough at 40 energy units from 1981 to 1989, it is rising at an accelerated pace, and is at 100 energy units in the year 2000. However, petroleum remains the dominant fuel, from the years 1981 to 2000.
