Insulation first, battery last: the order that saves thousands on energy

Lower your energy demand first through better insulation and draft-sealing. Then replace gas heating with a heat pump. Add solar next, and install a home battery last. This order saves $4,400 to $5,900 yearly.

Why it mattersGetting the order right cuts energy bills drastically. Many people miss the biggest savings by focusing on expensive batteries before tackling cheaper insulation upgrades.
