Is Electrification Worth It in Missouri?
St. Louis: Hot summers, cold-ish winters, and cheap energy.
About 4,900 heating degree days. Natural gas at $1.05/therm. Electricity around $0.11/kWh from Ameren Missouri. You need both heating and cooling, but neither is extreme. Most newer homes (post-2000) already have heat pumps because they're cost-effective in Missouri's moderate climate.
If you're replacing an old system, go with a heat pump. Your cooling efficiency gains alone will save $250-400/year, and heating costs will be similar to gas. Total payback around 7-9 years. If you're currently using propane or electric resistance, upgrade immediately—you're overpaying by $600-1,200 annually.
What Do Energy Costs Look Like in Missouri?
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?
I've broken down the economics 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.
