Guides to home energy rebates in 2026

Each guide answers one question a homeowner actually types — is there still a tax credit, what does my utility pay for a heat pump water heater, what pays for insulation — with every figure read on the official page and dated. Guides are written by service, across the states and utilities we have verified; the state registry and the utility pages hold the row-by-row detail, the deadline calendar the dates, and the corrections log every change we have made. When a guide’s facts change, the guide changes and the change is logged.
