Power Plant Fuel Types, Emissions & Pollution Factors

The state of Illinois’s primary fuel type utilized for electricity generation is Nuclear. They generate 56.21% of the total production in the state from this fuel. Totaling Nuclear with Coal (21.31%) and Natural Gas (11.83%), the three fuel types make up 89.35% of the generation in the state. About 3,023.36 kilograms of CO2 and CO2 equivalent emissions per citizen are emitted in the state, making them the 42nd worst polluter per capita in the nation. This adds up to total emissions of 38,311,512,180.8 kilograms of CO2 & CO2 equivalent gases from electricity production, making the state the 13th highest for total pollution in the United States. Illinois has the 11th most power plants of any state in the country, with 235 total plants. This translates to the 39th most power plants per person in the United States.

Net Metering

Companies offering net metering in Illinois include Commonwealth Edison & Ameren Illinois & MidAmerican Energy . At the state level, Illinois has decent laws for consumers interested in installing personal solar.

Energy Loss

There are 62 companies in Illinois that reported energy loss, including Commonwealth Edison, MC Squared Energy Services, and City Water, Light and Power Springfield. Combined, these 62 companies average an annual energy loss of 2.67% of electricity produced. The United States average for energy loss is 2.72%, which earns a rank of 40th worst in the country for Illinois in this category.

Solar Taxes And Rebates

When it comes to stimulating home installs of solar, one of the best uses of government resources is tax breaks and rebates for solar installs. Illinois currently does not offer a state tax credit for solar panel installation at a private residence. Residents in the state enjoy rebates for private solar installs of over $500. This is the highest amount we’ve seen in the nation. Unfortunately, residents in the state are only offered some optional tax exemptions for what they spend on solar installation. There is currently no sales tax exemption for consumers who install solar.

State Level Initiatives

Policies drawn up at the state level determine whether customers who are seeking renewable energy sources can easily find alternatives. Many states require green fuel types to be a percentage of the fuel used for electricity production. These guidelines are known as Renewable Portfolio Standards (RPS). While further enhancements could be made, Illinois requires for 1-15% of electric generation to come from renewable fuel sources. In addition, low income solar programs are another way a state can encourage renewable fuel types and the state of Illinois is home to a program that does exactly that.
