Why these numbers hold up

8 data sources, one answer

We cross-reference Census data, utility rate databases, Rewiring America, climate models, and more to give you the complete picture -- not just one program's marketing.

Math that shows its work

Loan payment vs. energy savings, month by month. You see whether an upgrade pays for itself -- and how quickly. No hand-waving.

60 seconds, not 60 minutes

No signup, no phone calls, no contractor visits. Enter your address and see everything available -- rebates, rate plans, financing -- instantly.

The math nobody shows you

Stack rebates, rate plan savings, and smart financing. Many upgrades pay for themselves from month one.
