Why Select This Indicator?

The end-use energy consumption indicator shows which sectors are driving energy consumption in the state. The trends indicate changes in growth rates (or declines) in end-use consumption by sector and how those rates are changing.

What Are The Trends?

Total end-use energy consumption increased 51 percent from 1970 to 1993. The trends in end-use consumption fall into three distinct periods. From 1970 to 1983 there were moderate levels of growth in total consumption. This growth accelerated between 1983 and 1990; much of the overall growth occurred during this period. Energy consumption increased in each of the end-use sectors. The growth in total end-use consumption leveled off after 1990. Key trends include:

• The most important cause of the overall increase in end-use consumption was a doubling of transportation sector energy use. Transportation increased its share of total consumption from 38 percent to 51 percent between 1970 and 1993. Growth in transportation energy consumption accounted for 77 percent of the growth in total end-use energy consumption during this period.
• Industrial energy consumption declined in both the 1970 to 1983 and 1990 to 1993 periods. It was the only sector to experience declines in consumption during these periods. The industrial share of end-use consumption declined from 36 percent in 1970 to 22 percent in 1993.
• Commercial sector use more than doubled from 1970 to 1993. Much of the increase occurred prior to 1982. The commercial share of total consumption increased from eight percent to 11 percent.
• Residential sector consumption increased 32 percent from 1970 to 1993, but its share of total consumption dropped from 17 percent to 15 percent.

What Does it Mean?

The transportation sector consumed over half of the total end-use energy in Washington in 1993. This explains why petroleum consumption accounted for the largest share of fuel consumption. Increases in transportation energy consumption were due to increased travel. The decline in industrial consumption was due largely to changes in the economy and shifts to less energy intensive industries. The rapid population growth experienced by the state was the principal cause of increased residential sector energy consumption, while strong growth in the service sector was responsible for increases in commercial sector energy consumption.

About the Data

End-use energy consumption data are obtained from the Energy Information Administration. The data are adjusted to remove all non-energy uses of petroleum (see Appendix D for more information).
