The pie charts compare the proportion of energy generated from five fuel sources, namely coal, gas, nuclear, renewables, and oil and other fuels in the UK from 2014 to 2018.
Overall, the charts show noticeable shifts in energy production over the given period, with nuclear and coal fuels seeing declines, whereas the reverse was true for renewable sources, which experienced an increase in energy generation. Gas, however, along with oil and other fuels remained unchanged across the whole timeframe. It is also noteworthy that the gas accounted for the highest share of its total energy production.
Gas clearly remained the dominant category throughout the period, despite remaining unchanged at 30.1%. Similarly, oil and other fuels bucked the trends, remaining static at 4.0% in both years. Renewable sources, on the other hand, were generated 15.0% by the UK initially, before rising significantly to 26.2% in the final year, respectively.
By contrast, the remaining fuels – nuclear and coal – witnessed opposing trends throughout the period, with the former declining at a moderate rate from 22.5% to 21.6% between 2014 and 2018. In contrast, coal, however, fell sharply from 28.4% in 2014 and 18.1% by 2018.
