Should a heat pump be worth it for home emissions with mixed electricity?

I’m trying to figure out if my family’s plan to install a heat pump is actually a good move for reducing our home’s emissions, or if we’re overlooking some bigger picture issue with the electricity it will use. Our power still comes from a mix of sources, including natural gas, so I’m feeling unsure if the switch really adds up.

We swapped to a heat pump last winter. It felt good on paper for emissions, but in practice the cold snaps kept shifting how clean the power looked. Our electricity is a mix, and on the coldest days the system pulled more kWh than I expected.

I learned that the big variable is the grid mix. If the grid clean up is real, a heat pump can cut emissions even with some gas in the mix; if the grid stays heavy on fossil fuel, the advantage shrinks or shifts to peak times.

There’s a bigger picture thing here that’s easy to miss: sealing the house and reducing leaks matters more than I thought. We did a quick weatherization after the install and it felt like a real change in comfort; the heating load dropped a bit, and that helped the math.

I ran a rough estimate using city grid data and our hourly usage for a month. It showed a modest drop in emissions, but the result bounced with temperature and wind. I’m not confident I’m reading it right, and I’m still unsure if this was the right move for us.
