Power Plant Fuel Types, Emissions & Pollution Factors

Coming in as the 17th worst ranked state in the country, Illinois releases 28,726,954,974.78 kilograms of CO2 emissions from electricity consumption. A better measurement of pollution is the CO2 levels per person in the state, which amounts to 2,283.17 kilograms of CO2 emissions per person per year from electricity use. Using this calculation Illinois is the 44th highest polluting state in the nation. Nuclear makes up 54.61% of the fuel sources used for electricity generation in the state of Illinois. Adding Nuclear totals to Natural Gas (16.24%) and Coal (14.94%), these three fuel types make up 154,740,098.77 megawatt hours (or 85.79%) of the state's electricity production. Illinois has 316 power plants, which is the 8th most in the United States and 33rd most when considering facilities per capita.

Illinois Net Metering

Illinois has 54 out of 113 electricity suppliers reporting that they offer net metering to residents with personal solar panels. The state of Illinois has above average state level net metering regulations.

Energy Loss

The average energy loss for companies in Illinois is 2.82%. This includes data from 22 companies, including Commonwealth Edison, MC Squared Energy Services, and City Water, Light and Power Springfield. With a nationwide average of 2.87%, Illinois is ranked as the 19th best state in the US.

Solar Taxes And Rebates

In order to foster solar panel installs at private residences, all a state needs to do is pass legislation with solar related tax and rebate incentives. Illinois, unfortunately, has no statewide tax credits offered to residents who install solar panels. The state offers rebates of over $500 to consumers who wish to install private solar panels at their home. Unfortunately, homeowners in the state are only offered some optional tax exemptions for what they spend on solar installs. Citizens in the state do not have access to a sales tax exemption when purchasing solar panels.

State Level Initiatives

Legislation enforced at the state level determines whether customers who are seeking renewable energy sources can easily find alternatives. Many states require green fuel sources to make up a percentage of the fuel used for electricity generation by suppliers in the state. These stipulations are referred to as Renewable Portfolio Standards (RPS). Illinois requires electricity companies to produce between 1-15% of their output from renewable fuel sources. Additionally, low income solar programs are another way a state can encourage renewable fuel sources and the state of Illinois is home to one such program.

Learn about going solar in Illinois, find out which system size is best for you, compare local installers and see which incentives are available in your area.
