Total Electricity Consumption in Iowa

Most economists link electricity consumption directly with economic growth. Analysts at the U.S. Department of Energy (DOE) Energy Information Administration (EIA) project that the U.S. gross domestic product will grow at an average annual rate of 2.9% per year through 2030. And they predict electricity consumption will grow over this same period at a rate of 0.8% per year. That means electric power consumption, and the accompanying infrastructure to produce and deliver electricity, will be about 43% greater in 2030 than it is today.

For Iowa, looking at past consumption trends is one good indicator for projecting growth rates into the future.
