These two pie charts show the proportion of the energy cultivated from different resources in a country in 1985 and 2003.
During this time, the percentage of each resource has changed little. Some had increased, and others had decreased.
When you focus on the type of resource which had go up toward 2003, they are natural gas, coal and other renewable.
On the other hand, the percentage of nuclear and oil diminished. The ratio of the sum of the two accounted for almost three quarters but that of 2003 dropped to about a half.
From these facts, you can find a trend in this graph. The energy produced by natural gas, other renewable and even hydrogen has less harmful effect on the earth.
They are eco-friendly energy compared to one by nuclear and oil.
Nowadays, more and more people pay attention to environmental problem. It will result in further decline of using nuclear and oil to generate energy.
