The two pie charts illustrate how electricity was generated in a European country in 1980 and 2020, across five energy sources.

Overall, the country shifted dramatically away from coal towards cleaner sources such as natural gas, nuclear power and renewables. Coal was by far the largest source in 1980 but had become a minor one by 2020.

In 1980, coal accounted for half of all electricity, more than the other four sources combined. Natural gas contributed 20 per cent, followed by nuclear at 15 per cent, oil at 10 per cent, and renewables at a mere 5 per cent.

By 2020, natural gas had become the leading source, rising to 35 per cent. Nuclear power nearly doubled its share to 30 per cent, while renewables tripled from 5 per cent to 15 per cent. In contrast, coal's share collapsed from 50 per cent to just 15 per cent, and oil fell slightly to 5 per cent.

In conclusion, the period saw a clear diversification and decarbonisation of the country's energy mix.
