The pie charts illustrate the sources of electricity generation in Germany in 1980 and 2010, measured in units.
Overall, it is clear that there was a significant shift towards conventional thermal power in 2010, while other sources either declined or remained relatively small.
In 1980, electricity production was more evenly distributed among different sources. Nuclear and renewables both accounted for 28 units, while coal contributed 22 units. Oil also made up a noticeable portion at 20 units, and hydro was the smallest source at only 7 units.
By contrast, in 2010, conventional thermal power became the dominant source, producing 155 units out of a total of 214 units. Meanwhile, nuclear and coal dropped significantly to 28 and 27 units respectively. Oil and hydro contributed the least, with just 2 units each.
