Worldwide Energy Use

All nations have contributed to the growth in use of energy, as is shown in Figure 4. The centrally planned economies include China, Russia, and other communist countries, and the nations making up the Organization for Economic Development and Cooperation are listed in Figure 4. The Carbon Dioxide Information Analysis Center provides global and regional contributions to fossil fuel CO ₂ emissions.

The Energy Information Administration provides a wide variety of energy-related statistics from the US Government. Figure 5 converts the national carbon emissions into the fractional contribution of each nation to greenhouse warming. This pie chart shows that the US is the major single contributor, accounting for 21% of the total. The former USSR and the European Economic Community are approximately the same at 14% and China is fourth at 7%. More recent figures likely will show China to be a much larger contributor, however.
