The pie charts compare the proportions of energy produced by five categories of fuels in the United Kingdom in 2014 and 2018. Overall, the figures for oil and gas remained the largest and smallest shares in both years. By contrast, that of coal and nuclear showed a downward trend, while renewables’ increased.
In both 2014 and 2016, as the dominant energy producer, gas constituted 30.1% of the overall energy generation in the UK. Meanwhile, oil and other resources produced only 4.0% of the total energy in both years, which consistently had the lowest.
Moreover, the percentage of coal started at 28.4% and dropped significantly to 18.1% between 2014 and 2018. Similarly, that of nuclear only decreased marginally by 0.9% from 22.5% to 21.6% during the period. Conversely, the trajectory of renewables differed from other fuels, which saw a notable growth from 15.0% to 26.2% over the period, overtaking nuclear and coal to become the second-largest energy generator in the United Kingdom in 2018.
