3. Energy Consumed by the Commercial Sector Total electricity usage strongly follows the total energy consumed by the commercial sector.

4. Energy Consumed by the Transportation Sector Petroleum dominates the transportation sector.

5. Energy Consumed by the Residential Sector Electricity is the primary energy source for the residential sector, followed by natural gas.

6. Energy Consumed by the Electric Power Sector Coal has always been the chief source of energy for the electric power sector. Natural Gas and Nuclear energy usage has increased greatly over the past decade.

7. Industrial Electricity Consumption Coal consumption occupies the greatest amount of total industrial electricity consumption.

8. Residential Electricity Consumption Coal is also used in the majority of residential electricity consumed. This data is similar to the industrial electricity consumption.

9. Transportation Electricity Consumption Overall, transportation electricity consumption has decreased. Coal produces most of the electricity used by transportation.

10. Commercial Electricity Consumption Coal produces most of the electricity used in the commercial sector.

11. Total Energy Consumption Total energy consumption has increased greatly over the past 50 years, with fluctuations in the 1970s. The industrial sector has always used the most amount of energy.
