The pie charts compare the proportions of energy production by different sources in Spain between 2008 and 2017. Overall, the reliance on fossil fuels (coal, oil, and gas) decreased over the period, while the share of renewable energy and other sources increased significantly.
In 2008, fossil fuels constituted the majority of energy production, with coal being the largest contributor at 28%, followed by oil at 27% and gas at 22%. However, by 2017, the production of energy from coal dropped markedly to 17%, and oil’s share also declined to 23%. In contrast, gas experienced a slight increase, rising by 1 percentage point to 23%.
On the other hand, the proportion of energy from non-fossil fuel sources saw a considerable rise. Renewable energy accounted for just 9% in 2008 but nearly doubled to 16% in 2017, representing the most significant growth among all categories. Nuclear energy production also rose, increasing from 11% in 2008 to 17% in 2017. Similarly, the category of “Other” energy sources, though small in both years, doubled from 3% to 6%.
In summary, Spain shifted towards cleaner energy sources between 2008 and 2017, with a decline in coal and oil usage and notable growth in renewable energy, nuclear energy, and other sources.
