Overview

Located in the center of the United States, Illinois is the most populous Midwestern state, and ranks sixth in the nation in population and fifth in GDP.1,2,3 Most of the state's residents are concentrated in a few large urban areas, leaving much of the state rural.4 Chicago, located in northeastern Illinois on the shores of Lake Michigan, is home to one-fifth of the state's population and is the third-largest U.S. city.5,6

Illinois plays an important role in the nation's economy because of its central location and extensive transportation network. The state has the nation's fifth-busiest commercial airport and the second-largest rail network with almost 7,000 route miles.7,8 Illinois has the third-largest number of interstate highways, after Texas and California, at about 2,200 miles, and it also has about 1,100 miles of navigable waterways. The state's inland waterway system connects the Great Lakes to the Mississippi River and the Ohio River, linking the central United States to the Atlantic Ocean and the Gulf of Mexico.9,10

Illinois is a key hub for crude oil and natural gas moving throughout the United States.

Illinois is a key hub for crude oil and natural gas moving throughout the United States.11 The state also has substantial coal reserves and some crude oil resources.12,13 Illinois is a major electricity generator and produces the most nuclear power among the states, and is a top supplier of wind power.14 The state has 26 million acres of farmland and ranks among the top 5 states in the market value of agricultural products sold.15,16 Corn and soybeans, the state's most important crops, provide feed for livestock and are used as feedstock for many ethanol and biodiesel plants.17,18,19,20

Illinois is the nation's sixth-largest energy-consuming and eleventh-largest energy-producing state. The state's industrial sector, which includes agriculture, accounts for three-tenths of Illinois's total energy use.21,22 Chemicals, food and beverages, machinery, fabricated metal products, and computers and electronics are the largest contributors to the state's manufacturing GDP. Other energy-intensive industries in Illinois include petroleum refining, coal mining, and plastics manufacturing.23 The residential sector accounts for one-fourth of the state's energy consumption, the transportation sector uses slightly less than one-fourth, and the commercial sector accounts for one-fifth.24 Despite the state's cold winters and its warm, humid, and occasionally hot summers, Illinois's total energy consumption per capita ranks near the midpoint of the states.25,26

Electricity

Illinois generates more electricity from nuclear energy than any other state, accounting for one-eighth of the nation’s total nuclear power generation.

Illinois is the nation's fifth-largest electricity producer, and typically sends about one-fifth of the power it generates to other states over the regional grid.27,28 Illinois generates more electricity from nuclear energy than any other state, accounting for one-eighth of the nation's total nuclear power generation.29 In 2023, the state's 6 nuclear power plants, with 11 total reactors, produced 54% of the state's electricity net generation.30,31 Five of the six nuclear plants rank among the 10 largest power plants in the state by generating capacity and all six by annual electricity generation.32 Because of economic issues in the electricity market, several of the state's nuclear power stations were scheduled to close, but the Illinois legislature in 2016 approved financial incentives to keep the stations operating.33 The utility that owns two nuclear power plants in northern Illinois, the Byron and Dresden generating facilities, reversed its plans to retire the nuclear power plants in the fall of 2021 after a new state law passed that requires Illinois to transition to 50% clean energy by 2040 and 100% clean energy by 2050.34,35,36,37 Illinois has the only chemical facility that converts uranium yellowcake into uranium hexafluoride, a step in making fuel for use at nuclear power reactors.38,39,40

Coal-fired power plants have been the second-largest electricity providers in Illinois from 2009 until 2023. However, coal's contribution to in-state generation declined significantly from 46% of electricity net generation in 2009 to 15% in 2023, as about 9,000 megawatts of coal-fired generating capacity shut down during that period in response to stricter emissions regulations and economic pressures. About 2,700 megawatts of coal-fired capacity shut down in 2022.41,42,43,44 The state's natural gas-fired generation reached its highest level ever in 2023. Natural gas-fired power plants provided almost 16% of Illinois's electricity net generation in 2023, about four times more than a decade earlier. Wind-powered generation closely followed, accounting for 12% of in-state generation. Other renewables, led by solar power, biomass, and hydropower, accounted for almost all the rest of the state's net generation in 2023.45

About 96% of Illinois households use electric air conditioning, but only one in five Illinois households rely on electricity for home heating.46,47 Electricity retail sales in Illinois do not vary greatly among end-use sectors. The commercial accounts for 35%, the residential sector 33%, and the industrial sector 31% of the state's electricity retail sales. A small amount of electricity goes to the transportation sector for light-rail.48

In July 2024, Illinois had 1,322 public electric vehicle charging locations.49 The largest number of charging locations are around the Chicago area.50 The Illinois Department of Transportation updated the Illinois Electric Vehicle Infrastructure Deployment Plan last year, with a goal to have 1 million electric vehicles in the state by 2030 and expand charging infrastructure through public-private partnerships.51

Coal

Illinois’s estimated recoverable coal reserves are the second largest in the nation.

Illinois has 15% of the nation's economically recoverable coal reserves, second only to Montana, and it is the nation's fourth-largest coal producer after Wyoming, West Virginia, and Pennsylvania.52,53 In 1673, Europeans first discovered coal in North America along the Illinois River, and coal underlies about two-thirds of the state. However, coal was not mined in the state until the early 1800s.54,55 Coal mines in Illinois provide 6% of U.S. total coal production.56

Illinois exports about one-fourth of the coal mined in the state to other countries.57 Typically, about 11 states receive Illinois coal primarily to generate electricity, with Kentucky and Florida receiving the most coal.58 Illinois produces only bituminous coal, which has a high sulfur content. Many electric utilities burn that coal in combination with lower sulfur coal from other regions to meet federal Clean Air Act emissions regulations.59,60,61 Coal from Illinois is transported to other states mainly by rail and truck.62 Illinois consumes about one-fourth of the coal mined in the state, most of which is used in the electric power sector.63,64 Nearly all the coal that Illinois receives from other states comes from Wyoming by rail and is also used for electric power generation.65 Industrial and coking plants account for one-tenth of the state's coal consumption.66

Petroleum

Illinois has the fourth-largest crude oil-refining capacity of any state.

Illinois is a major crude oil-refining state. Its 4 refineries can collectively process about 1 million barrels of crude oil per calendar day into petroleum products, the largest refining capacity in the Midwest and the fourth largest in the nation after Texas, Louisiana, and California.67,68 The largest refinery in the state is the Wood River refinery, located in southwest Illinois close to the Mississippi River near St. Louis, Missouri. It can process 356,000 barrels of crude oil per calendar day.69,70 Another refinery operates in southern Illinois, and two more operate in northeastern Illinois. The state's refineries process domestic crude oil, as well as Canadian and other imported crude oils, into motor gasoline, diesel fuel, jet fuel, and other petroleum products.71,72,73,74

The state's crude oil reserves and production are modest.75,76 Most of the producing wells in Illinois are located in the Illinois Basin in the southern half of the state.77 Oil exploration in Illinois began in the 1860s, but commercial production did not occur until 1905. Since the 1860s, tens of thousands of wells have been drilled in the state. Crude oil production in Illinois peaked in 1940, reaching almost 150 million barrels that year. In 2023, the state's oil production decreased to just under 7 million barrels, the lowest output level since the mid-1930s.78,79 Most of the oil wells in the state are stripper wells that each produce on average less than 2 barrels of crude oil per day.80

Several crude oil and petroleum product pipelines cross Illinois and the state is home to the Patoka Terminal crude oil storage hub, which has 80 storage tanks that can hold more than 19 million barrels.81,82 Illinois has crude oil ports at Chicago on Lake Michigan and at Peoria on the Illinois Waterway, which connects Lake Michigan to the Mississippi River. Both ports also handle small amounts of petroleum product imports.83,84,85

Illinois consumes the sixth most petroleum of any state. The transportation sector accounts for almost three-fourths of Illinois's petroleum consumption, and about two-fifths of the state's petroleum use is motor gasoline.86,87 Reformulated motor gasoline blended with at least 10% ethanol, which reduces smog-forming emissions, is required to be sold in the areas around Chicago in northeastern Illinois and around the St. Louis, Missouri, suburbs in southwestern Illinois.88,89 There are 282 public fueling stations throughout the state that sell E85, a blend of 85% ethanol and 15% gasoline. Only California, Minnesota, and Iowa have more E85 refueling stations.90,91 In February 2024, federal regulators approved the sale of gasoline with up 15% ethanol (E15) throughout the year in Illinois and seven other Midwest states starting in 2025. Previously, E15 gasoline was banned during the summertime due to concerns that it caused smog in hotter temperatures.92 Illinois is a busy aviation hub and about one-eighth of petroleum used in the state is jet fuel, making it the fifth-largest consumer of jet fuel among the states.93,94

Nearly one-fourth of the petroleum consumed in Illinois is used in the industrial sector, the state's second-largest petroleum-consuming sector.95 The industrial sector also uses about two-thirds of the hydrocarbon gas liquids (HGLs), including propane, ethane, and ethylene, consumed in Illinois.96 Farmers use propane to dry the state's corn crop after harvest, and industry uses ethane and ethylene as feedstock for making plastics.97,98,99 Overall, Illinois is the fourth-largest HGL-consuming state and HGLs account for about one-tenth of the state's petroleum consumption.100,101 The residential and commercial sectors combined make up 5% of the state's petroleum use. About 5 in 100 Illinois households use petroleum products, mostly propane, for home heating.102 A small amount of petroleum is used in the state's electric power sector.103

Natural gas

Illinois has 11% of total U.S. natural gas underground storage capacity, the second highest among the states.

Illinois has few natural gas reserves and little production. 104,105 However, the state is a major natural gas crossroads, with many interstate natural gas pipelines and two natural gas market hubs.106 Natural gas supplies enter Illinois primarily from Iowa, Indiana, Missouri, and Kentucky. Slightly more than half of the natural gas that enters Illinois continues on to the east through Indiana, to the north via Wisconsin, and to the south through Missouri.107 Some of the natural gas that enters Illinois stays in the state's 28 underground natural gas storage fields, which have a total storage capacity of just over 1 trillion cubic feet of natural gas, the second highest among the states and equivalent to 11% of U.S. total natural gas underground storage capacity.108

Illinois is the eighth-largest natural gas-consuming state in the nation.109 The residential sector accounts for about one-third of the natural gas consumed in the state, the largest share of any sector.110 Almost 8 in 10 Illinois households use natural gas for heating.111 The industrial sector is the second-largest natural gas-consuming sector in Illinois, making up one-fourth of the state's total. The state's commercial sector and electric power sector each account for about one-fifth of natural gas use.112

Renewable energy

In 2023, Illinois ranked fifth in the nation in wind power capacity with about 7,900 megawatts installed.

In 2023, renewable resources generated 14% of Illinois's total in-state electricity generation, more than double the amount generated a decade earlier. Wind is the primary renewable resource used for electric power generation in the state. In 2023, wind power provided 85% of the state's renewable generation and Illinois ranks fifth in the nation in utility-scale (1 megawatt or greater) wind power generating capacity, with about 7,900 megawatts.113,114 About 1,200 megawatts of additional wind power capacity are scheduled to come online by 2026.115 Illinois's best wind energy resources are found in the northern one-third of the state.116

In 2023, Illinois's total solar power generation from both utility-scale facilities (1 megawatt or larger in capacity) and small-scale, customer-sited solar panel systems (less than 1 megawatt each) accounted for 13% of the state's renewable electricity. The largest solar power facility in Illinois, the 200-megawatt Prairie Solar Farm, came online in late 2021. About three-fifths of the state's solar generation in 2023 came from utility-scale facilities and the rest was small-scale generation, mostly from rooftop solar panels.117,118 Biomass and hydropower together generated 1% of Illinois's renewable-sourced electricity. Waste and methane gas from municipal landfills fuel nearly all of the state's biomass electricity generation at 12 facilities with 55 megawatts of combined generating capacity.119,120 Illinois has many rivers, but the state's relatively level terrain limits hydroelectric potential. The state's 8 hydroelectric facilities have a total of 33 megawatts of generating capacity.121

Illinois's primary renewable energy product is biofuels. The state is a leading producer of both ethanol and biodiesel, with an annual production capacity of 1.9 billion gallons of ethanol and 192 million gallons of biodiesel. A fertile prairie state, Illinois is a major corn and soybean producer. The state's 13 ethanol plants use corn as feedstock, and the state's 4 biodiesel plants use multiple feedstocks, including soy and corn oils.122,123,124 Illinois's annual ethanol production of 1.4 billion gallons is the third-highest in the nation, after Iowa and Nebraska, and is more than three times larger than the state's annual ethanol consumption of 432 million gallons.125,126 Illinois produces 168 million gallons of biodiesel, the third-highest after Iowa and Missouri. The state is the third-largest consumer of biodiesel at 163 million gallons.127,128

Illinois has a renewable portfolio standard (RPS) that requires all investor-owned electric utilities and alternative retail electricity suppliers to obtain increasing proportions of the power they sell from renewably-sourced generation. In 2021, the RPS target was increased to require that 50% of electricity retail sales come from renewable sources by 2040, replacing the earlier target of 25% by 2026.129,130 The RPS will help Illinois reach its goal for its economy to have net zero carbon emissions by 2050.131
