Energy Facts by State

Because of many local laws and guidelines, energy production and use is highly dictated by each state government. Below is a state-by-state assessment of energy production and use in the Midwestern US (from


  • Illinois is a key transportation hub for crude oil and natural gas moving throughout North America, with over a dozen interstate natural gas pipelines, two natural gas market centers, several petroleum and petroleum product pipelines, and an oil port.
  • In 2010, Illinois’ producing coal mines had the third largest recoverable coal reserves in the nation. It also ranked first in the nation for both generating capacity and net electricity generation from nuclear power; generation from its nuclear power plants accounted for 12% of the nation’s total.
  • In 2011, Illinois led the Midwest in crude oil refining capacity and ranked fourth in the nation.
  • With a production capacity of 1.5 billion gallons per year, Illinois is a top producer of ethanol; it ranked third in the United States in 2011.


  • Indiana’s industrial sector, which includes manufacturers of aluminum, chemicals, glass, metal casting, and steel, consumed more energy in 2010 than the residential and commercial sectors combined.
  • The largest geothermal heating and cooling system in the United States is being built in Muncie, Indiana.
  • Indiana ranked seventh among all states in coal production in 2010, and coal-fired electric power plants provided 83% of Indiana’s net electricity generation in 2011.
  • In 2011, the Whiting oil refinery had the largest processing capacity of any refinery outside of the Gulf Coast region.
  • Indiana is a major producer of ethanol;; in 2011, it had 13 ethanol plants capable of producing 906 million gallons per year.


  • The use of liquefied petroleum gases (LPG) in the residential and industrial sectors contributes to Iowa’s relatively high consumption of LPG.
  • Iowa was the largest producer of ethanol in the United States in 2011, accounting for 27% of the nation’s fuel ethanol production.
  • Seventy-seven percent of Iowa’s 2011 net electricity generation came from electric utilities; most of the rest came from independent power producers.
  • In 2011, Iowa was ranked third in the share of net electricity generation from non-hydroelectric renewable energy resources.
  • Wind provided 19% of Iowa’s total electricity generation in 2011;; it was second only to coal as an energy source for electricity generation in the state.



  • In 2010, Michigan had more underground natural gas storage capacity—1.1 trillion cubic feet—than any other state in the nation.
  • The Antrim Gas Field, located in Michigan’s Lower Peninsula, was ranked 15th in the nation in estimated wet natural gas reserves as of 2009 and produced an estimated 126 billion cubic feet of gas that year.
  • In 2011, Michigan’s three nuclear power plants, with four reactor units, provided 30% of the state’s net electricity generation.
  • Michigan used coal for 54% of its net electricity generation in 2011;; much of its coal is imported from Wyoming.
  • Biomass from Michigan’s almost 19 million acres of forest land provided fuel for 54% of Michigan’s renewable net electricity generation in 2011.


  • Two nuclear power plants near Minneapolis-St. Paul, the Monticello reactor and the Prairie Island I and II reactors, account for 22% of Minnesota’s net electricity generation.
  • Despite its extremely cold climate, Minnesota ranked 20th among all states for per capita energy use in 2010.
  • Minnesota ranked fourth in the nation for ethanol production in 2011, and has approximately two dozen ethanol production plants.
  • Fifty-three percent of the electricity generated in Minnesota came from coal-fired electric power plants in 2011;; most of its coal supply was brought in by rail from Montana and Wyoming.
  • Minnesota ranked fourth in the nation in net electricity generation from wind energy in 2011;; its net generation was 6.8 million MWh in 2011, an increase of 42% from 2010.


  • Current interest in Ohio oil and gas exploration is focusing on two of its shale formations—the Marcellus Shale and the Utica Shale.
  • In August 2003, a transmission failure in Ohio led to the largest blackout in North American history, affecting over 50 million people.
  • Ohio had the eighth largest crude oil refining capacity in the nation in 2011.
  • Coal fueled 78% of Ohio’s net electricity generation in 2011, nuclear energy contributed 11%, and natural gas added another 8.9%.
  • Ohio ranked fifth in the nation in 2010 in energy consumption by the industrial sector; in 2011, Ohio ranked third in manufacturing employment, with 5.4% of US manufacturing jobs.


  • Wisconsin’s industrial sector, which includes energy-intensive industries such as food processing, chemical manufacturing, plastics, and forest products, was the highest energy-consuming sector in the state at 577 trillion Btu in 2010.
  • In 2010, Wisconsin produced 438 million gallons of ethanol and ranked ninth among all states in ethanol production.
  • Coal has dominated electricity generation in Wisconsin; in 2011, it provided 63% of the state’s net electricity generation.
  • Point Beach nuclear power plant’s Unit 1 reactor, one of the oldest operating reactors in the United States, started commercial operations in 1970;; in 2005, its operating license was extended 20 years (for a total of 60 years).
  • In 2011, 8.4% of Wisconsin’s net electricity generation came from renewable energy resources, split among conventional hydroelectric power, biomass, and wind.
