Save Energy in Missouri: Practical Tips for Lower Utility Bills

Missouri experiences a mix of hot, humid summers and cold winters, which means residents face high energy demands year-round. Air conditioning is essential during the summer, while heating costs climb in the winter. Fortunately, Missouri homeowners can take a number of steps to improve energy efficiency, lower utility bills, and reduce environmental impact.

1. Maintain and Upgrade Your HVAC System

Heating and cooling can account for over 50% of a Missouri household’s energy use. Schedule seasonal maintenance to ensure your HVAC system runs efficiently. Replace dirty filters monthly during peak heating and cooling seasons, and consider upgrading to an ENERGY STAR® unit if your system is over 10 years old.

2. Install a Programmable or Smart Thermostat

In Missouri’s climate, temperature control plays a major role in energy costs. A programmable thermostat allows you to reduce heating and cooling when you’re away, saving 10–15% on your annual bills. Smart thermostats can adjust settings automatically based on your habits.

3. Seal Leaks and Improve Insulation

Air leaks in ductwork, windows, and doors can waste significant amounts of energy. Seal gaps with weatherstripping and caulk, and add insulation to attics, basements, and crawl spaces to prevent heat loss in winter and heat gain in summer.

4. Manage Sunlight and Heat Gain

Use reflective blinds or thermal curtains to block heat during the summer. In winter, open curtains during sunny days to allow natural warmth to enter, then close them at night to retain heat.

5. Upgrade to Energy-Efficient Appliances

When replacing appliances, choose models with the ENERGY STAR® label. High-efficiency refrigerators, dishwashers, washers, and dryers consume less electricity and water, which saves money over time.

6. Switch to LED Lighting

LED bulbs use up to 80% less electricity than traditional incandescent bulbs and last much longer. Replacing your home’s lighting is an easy, cost-effective way to reduce energy consumption.

7. Use Ceiling Fans for Comfort

Ceiling fans help circulate air and allow you to adjust your thermostat by a few degrees without sacrificing comfort. In summer, set fans to rotate counterclockwise; in winter, switch to clockwise to push warm air downward.

8. Reduce Water Heating Expenses

Lower your water heater’s temperature to 120°F, insulate the tank and hot water pipes, and install low-flow showerheads and faucets to reduce both energy and water usage.

9. Take Advantage of Missouri Energy Rebates

Utilities like Ameren Missouri and Evergy offer rebates for energy-efficient appliances, HVAC systems, and home weatherization. Check the Missouri Department of Natural Resources for updated programs.

10. Explore Renewable Energy Options

Solar power is increasingly accessible in Missouri, and net metering policies allow homeowners to receive credits for excess electricity generated. This can significantly lower your long-term energy costs.
