The pie charts compare the distribution of different kinds of energy consumption in the UK over the period from 2000 to 2010.
Overall, it is evident that coal remained dominant component in both years, although its proportion increased over time. Meanwhile, petrol experienced a noticeable change, whereas the remaining categories underwent relatively minor fluctuations.
In 2000, coal accounted for 30.0%, making it by far the most significant component. This was followed by gas and petrol, which comprised 29.5% and 29.0%, respectively, whereas solar represented a more modest share at 6.5%. Collectively, these four categories constituted 95% of the total. By contrast, other accounted for only just 5.0%, indicating that it made a negligible contribution to the overall distribution in that year.
Turning to 2010, coal remained predominant at 31.0%, despite a significant increase, while gas climbed significantly to 30.0%. Notably, petrol experienced the pronounced shift, falling from 29.0% to 20.0%. Meanwhile, solar underwent moderate change to 10.0%, whereas other rose slightly to 9.0%, suggesting that overall pattern remained broadly similar despite some redistribution among the categories.
