The pie charts illustrate the proportion of energy generation by fuel type in the UK over a 5-year period.
Overall, in both years, gas was the primary source of energy generation, while oil and other sources were the lowest contributors. However, by 2018, gas and oil still remained the dominant fuel sources. In contrast, the renewable source significantly decreased in 2018.
In 2014, gas was the dominant source of energy generation by fuel type in the UK, registering a significant figure of 30.1%. Although this proportion remained unchanged at 30.1% by 2018, it still remained the top contributor overall. In stark contrast, the share of energy generated from oil and other sources stood at a modest 4% in the initial year. However, this sector remained completely unchanged over the 5-year period, finishing at 4% by the final year.
Moving to the remaining energy generation categories, coal accounted for 28.4% of the total energy production at the beginning of the period. Following this, the reliance on coal decreased, with its figure declining to 18.1% in 2018. Conversely, energy generation produced from renewable sources stood at 15%. This category, however, experienced a dramatic surge, peaking at 26.2% by the end of the period, which made it the fastest-growing sector on the chart. One last energy generation source was Nuclear; Nuclear was the 3rd largest energy generation source in the UK in 2014 at 22.5%, although this proportion decreased to 21.6% by 2018.
