This weeks segment looks at how Iowa’s energy consumption has increased over the years.

Transcript:

Iowa’s energy consumption has increased over the years—but have we been moving in a greener direction?

This is the Iowa Environmental Focus.

Iowa’s population has grown from two and a half million in 1960 to just over three million now, and our methods of producing energy have grown and changed over the decades. In the 60s, Iowa was mostly run on natural gas and coal. Wind energy didn’t enter our sphere until the late 90s. Now, coal is our primary source of energy, followed by natural gas and wind.

The consumption of energy is measured in BTUs—British Thermal Units, with each unit representing the amount of energy needed to heat one pound of water one degree Fahrenheit. 

In the 60s, the average Iowan used about 217 million BTUs of energy per year. In 2016, that number jumped to a consumption of 488 million BTUs per Iowa every year, over double the amount of energy despite a population increase of less than a million.

New technology and an increased energy grid are partly to blame, but Iowa would benefit from cutting down energy use when possible, and relying more heavily on green energy—like solar and wind—to light our homes.
