The two pie charts compare the accumulation of electricity generated by seven different resources in Scotland: hydro pump storage, gas, other renewables, nuclear, hydro natural flow, oil, and coal. The data spans two decades, indicating percentages for each resource for both periods.
Overall, the trends in electricity generation between the two periods differ significantly. Notably, nuclear energy, other renewables, and oil saw increased production last year compared to two decades ago. Nuclear energy production was at 26.4%, which represented a 34% increase. Additionally, other renewables and oil experienced substantial growth, increasing by around 50% when compared to twenty years ago, reaching peaks of 5.1% and 4.0%, respectively.
It is clear that while other renewables and oil surged in the recent period, the output of some other generators declined. For instance, coal dropped to 41.4%, hydro natural flow decreased to 7.9%, and hydro pumped storage fell to 2.2%.
Despite these differences, there are some similar patterns between the two periods. Coal generation was consistent over the years, reaching 41.4% and experiencing a minor decline of 8.7% last year, bringing it to precisely 32.7%.
