The chart below each illustrates the electric generation by source in

China

and

Spain

. We can find out that renewable

sources

became a dominant feature for electric generation in both

China

and

Spain

in 2015, after the 10-year gap. First of all, the difference between 2005 and 2015 in

China

is pretty apparent. In 2005, Coal had a great portion among all of the

sources

, which made

China

dependent on coal.

However

, the trend changed in 2015. By reducing the amount of coal usage,

China

's renewable source usage was 10% increased than before. Compared to

China

,

Spain

had quite an even number among the

sources

in 2005. The impressive feature different from

China

is that

Spain

's oil & gas usage was 32%, which was the highest percentage in 2005. But after the 10-year gap, it totally changed. Renewable

sources

turned out to become the main source, which is the same as

China

.

Instead

of consuming coal, oil & gas, it is quite definite that both two countries focused on producing renewable

sources

for electricity generation.
