Illinois’ massive new clean energy bill, signed into law last this month, is a landmark in the state’s battle against climate change: a systematic plan for boosting solar and wind power, getting a million electric cars on the road, and phasing out coal and natural gas by 2050.

Whether you’re installing solar panels, buying an electric car, or just looking for a break on your electricity bill, the energy law offers incentives, both new and familiar. Estimated savings range from 5% to 10% on your electric bill, $4000 on an electric car purchase and about $8,000 to $9,000 on a new rooftop solar energy system for your home.

On the transportation front, the new law offers a $4,000 rebate for people buying electric cars, starting in July. The rebate falls to $2,000 in 2026 and $1,000 in 2028.

The upfront cost for installing a solar rooftop is about $22,000 in Illinois, said Delurey, but the state will pay for about $8,500 of that through an incentive program, and you can claim a hefty 26% rebate on that initial cost on your federal taxes. That reduces your upfront costs by about $14,200, making the tab about $7,800.
