Energy in Illinois

Following is an overview of Illinois' consumption and production of transportation fuels, electricity, and heating fuels, as well as the mandates and initiatives that affect the state's energy supply and economy.
Transportation fuels (gasoline and diesel fuel)
According to the Energy Information Agency, Illinoisans consumed 5.0 billion gallons of gasoline in 2009 and 2 billion gallons of diesel fuel in 2008. The state leads the Midwest in crude oil refining capacity with its four oil refineries - two are located near Chicago; one is in Robinson, near the Indiana border; and one is in Roxana, near St. Louis, Missouri. Illinois receives most of its crude oil from Canada and the U.S. Gulf Coast. The state is also a central hub for crude oil pipelines moving throughout the country, with a number of major pipelines converging in Illinois.

Illinois is among the top producers of ethanol in the country, providing a large amount of its output to other states. There are 10 ethanol plants in Illinois with four under construction. Several regions of Illinois - including the Illinois suburbs of St. Louis and the Chicago metropolitan area - have mandated that gasoline be blended with ethanol in an attempt to reduce emissions. Illinois is also home to four biodiesel plants.

Illinois is one of the leading electricity-producing states in the country and a top exporter of electricity to other states. About one-half of Illinois' power comes from nuclear plants. The state has six nuclear power plants with 11 operating reactors, making it the top state in nuclear power generation.

Nearly half of the state's energy production comes from coal. While Illinois has an estimated one-tenth of the nation's recoverable coal reserves, only a small amount of the reserves are found at producing mines. Illinois provides more than half of its coal production to other states. Natural gas and renewable energy supply the remaining energy used in the state.
Natural gas
Heating fuels
More than four-fifths of Illinois households use natural gas as their primary source of heat. While the state produces almost no natural gas itself, Illinois has the second largest natural gas storage capacity in the country. The state is a major transportation hub for natural gas supplies moving across the country through pipelines, many of which converge at the Chicago Hub and ANR Joliet Hub.

Illinois' existing energy mandates
Biofuel tax incentive
In 2003, Illinois passed legislation to create tax incentives for biodiesel and ethanol. The legislation provided for a partial sales tax exemption on biodiesel blends with 1-10% biodiesel (B1-B10) and a full sales tax exemption on blends higher than 10% (e.g., B20). It also eliminated state sales tax on E85 fuel blends (a mix of 85% ethanol and 15% gasoline) and reduced sales tax on E10 blends (a mix of 10% ethanol with 90% gasoline).
Renewable Fuels Development Program
Illinois developed the Renewable Fuels Development Program in 2003 to provide grants for construction projects of new renewable fuels plants that have an annual production capacity of 30 million gallons or more. The program also provides grants for expansion projects of existing biofuels production facilities that have a minimum capacity of 30 million gallons per year.
Alternative fuel vehicle and alternative fuel rebate program
The state offers rebates on purchases of alternative fuel vehicles, including those that use biodiesel or ethanol. In addition, the program provides rebates for the additional cost of using B20 or E85 fuels in these vehicles.
