The two pie charts illustrate the proportions of five different types of energy consumption in the UK in 2000 and 2010, with figures expressed as percentages.
Overall, coal and gas remained the dominant sources of energy across both years, while petrol experienced a notable decline. In contrast, renewable and alternative sources such as solar and other forms of energy increased their shares.
It can be seen that in the UK, the largest proportion of energy consumption was occupied by coal, accounting for 30% in 2000, followed by gas and petrol at 29.5% and 29%, respectively. In addition, solar and other sources represented the smallest shares.
By 2010, coal consumption rose marginally to 31% and gas slightly increased at 30%. However, petrol saw a significant drop to 20%, making it the third-largest contributor. Conversely, solar energy grew to 10%, and other sources almost doubled to 9%, indicating a shift towards more diverse energy use.
