The pie charts shows changes in the proportions of energy produced in a country from 1983 to 2003. It contains the energy such as hydropower, oil, nuclear power, coal, and natural gas. The red shape represent the hydropower, the blue shape represent the natural gas, the orange shape represent the oil, the gray shapes represent the nuclear power, the yellow shape represent the coal. The data was measured in percen per energy that divided into five energy from 1983 until 2003.
The hydropower energy remained fluctuated for 4 percen from 1983 until 2003. The oil and the coal decreased from 1983 until 2003. Whereas, the nuclear power and natural gas increased form 1983 until 2003. The coal decreased gradually from 42 percen to 38 percen, and the oil decreased significantly from 23 percen to 11 percen. Compared to, the nuclear power increased slightly from 20 percen to 24 percen, and the natural gas increased significantly from 11 percen to 21 percen.
The proportions of energy that produced by the country having a different result. In contrast, the hydropower energy remained fluctuated, whereas the oil and the coal decreased, instead of the natural gas and nuclear power increased in within 20 years.
