Our system will evaluate the answer based on this AI-generated description.
The image displays two pie charts indicating the amount of electricity generated in Scotland by energy source for two different periods- 20 years ago and last year. For 20 years ago, it shows coal at 41.4%, gas at 22.3%, nuclear at 19.9%, hydro natural flow at 8.7%, hydro pumped storage at 3.1%, other renewables at 2.8%, and oil at 2.1%. For last year, it shows coal at 32.7%, nuclear at 26.4%, gas at 21.7%, other renewables at 5.1%, hydro natural flow at 7.9%, oil at 4.0%, and hydro pumped storage at 2.2%.
Given the complexity of the image, the above description may not be entirely accurate.

The pie charts present the comparative data about different energy sources that produce electricity in Scotland for 20 years ago and last year.
In twenty years back, Scotland mostly depended on natural sources as coal and gas in producing their electricity which was 41.4% and 22.3% of the total sources. However, a downward trend has been observed in electricity generation from coal and gas which is decresed at 32% and 21.7% in the last year . Noticeably, in recent years, government focus has been shifted to renewable sources like neclear, hydro natural flow and other renewables in compare to 20 years back.
The evidence shows that amount of natural sources of energy such as gas,oil. coal are decreased over the two decades. Therefore, plan for alternative sources are come into light .
