Overall

, it can be seen that among the 7

energy

sources

, only nuclear, oil and other renewable

energy

sources

have increased over the past

year

compared to two decades. The various

sources

of

energy

used in Scotland and the amount of

energy

gained from each of them have not significantly changed when comparing the values from

last

year

and

twenty

years

ago. The greatest amount of

electricity

was generated from coal, with 41.4% being generated

’s data. Compared to

twenty

years

ago, the country has made slight changes to its reliance on certain

sources

for the generation of

electricity

.

Although

the major generation remains coal ( followed again by gas,) there has been an increase in the use of oil from 2.1% to 4.0%, nuclear

energy

( from 19.6% to 26.4%) and other renewable

sources

( from 2.8% to 5.1%) The most significant changes would be to the use of oil and other renewable

sources

, as the use of these two

sources

last

year

was almost double the percentage of

electricity

that was being generated from them

twenty

 

years

 ago.
