The pie chart illustrates the proportions of energy generation using different fuel sources in the UK over two separate years, 2014 and 2018. Overall, while nuclear energy and coal recorded a decline in the production of energy over the 2014-2018 period, renewable energy followed an upward trajectory; however, oil & other and gas stood out as the sole exception, remaining largely unchanged throughout the timeframe. Notably, gas consistently recorded the highest figures, whereas oil and other types of energy remained the lowest. Additionally, of all kinds of fuel, renewable energy demonstrated the most pronounced growth throughout the period.
Examining the falling trends, the percentage of nuclear energy in the UK decreased slightly, starting at 22.5% in 2014 and declining to 21.6% by 2018. Similarly, coal experienced a significant drop over the period. With an initial figure of 28.4% in 2014, the proportion of coal decreased considerably to 18.1% by the year 2018.
By contrast, renewable energy completely bucked this trend. The percentage of renewable energy accounted for 15.0% in 2014 – a figure that went on to increase sharply to 26.2% in 2018. Meanwhile, the proportion of gas and oil and other fuels amounted to 30.1% and 4.0%, respectively, in 2014, thereafter remained unchanged until 2018. Moreover, among all fuel sources, these two – gas and oil and other fuels – showed the lowest and highest figures.
