The federal energy tax credits have expired
Costs and payback figures on this page may still assume a federal credit that no longer exists. The 30% Residential Clean Energy Credit (25D) and the Energy Efficient Home Improvement Credit (25C) both ended for property placed in service after 31 December 2025, and the home EV charger credit (30C) ended after 30 June 2026. Assume no federal credit on work done today.
What expired, and what still exists →Is Electrification Worth It in Wisconsin?
Green Bay gets 7,600 heating degree days. Can heat pumps really handle that?
Yes, but you need the right equipment. A basic 14-SEER heat pump from Home Depot will struggle when it's -5°F and run up your electric bill with resistance heat. But a Mitsubishi Hyper-Heat or Fujitsu -15H? They'll keep running efficiently down to -15°F, which covers all but the coldest 5-10 days of a Wisconsin winter.
If you're heating with propane or oil, switch to a cold-climate heat pump and watch your bills drop 40-50%. If you have natural gas ($1.10/therm in Madison), the math is tighter—probably 10-12 year payback. The key is getting a quality cold-climate model installed correctly. Cheap out on equipment or installation, and you'll regret it.
What Do Energy Costs Look Like in Wisconsin?
Here's the real data from EIA (Energy Information Administration). These are the rates that determine whether electrification makes financial sense.
Visual ROI Analysis
Payback Period Comparison
Lower is better • Shortest payback = fastest return on investment
Annual Savings Comparison
Higher is better • More annual savings = greater long-term benefit
Cumulative Net Savings Over Time
Point where line crosses $0 = payback achieved • Steeper line = faster savings growth
Which Upgrades Pay Off the Fastest?
The economics are broken down for each major upgrade. Pay attention to the payback period—that's how long until savings equal your net cost.
Heat Pump HVAC
Solar Panels
Heat Pump Water Heater
EV Charger + Electric Vehicle
Should You Go All-In?
Here's what it costs to electrify everything at once—heat pump HVAC, solar panels, heat pump water heater, and EV charger. The upfront cost is high, but so are the savings.
Best ROI for Wisconsin
Based on your state's energy costs and climate, EV Charger offers the best return on investment with an average payback of 1.3 years and an ROI of 1390%.
0.0 years slower than average compared to the national average.
