How Does Weather Affect Energy Bills?

How Does Weather Affect Energy Bills?Energy bills account for a large portion of the average household expenses. During our hot, humid summers, cooling costs can rise significantly. Here are ways weather conditions increase your energy bill and how to reduce those costs.

Soaring Heat

As air temperatures rise outside, that heat doesn’t just stay put. Instead, following the laws of physics, it moves towards cooler areas. This means heat will infiltrate the home to warm the interior, and your air conditioner will use more energy to keep things cool.

You can block much of this heat by sealing air leaks and adding insulation to your attic and exterior walls. If you haven’t done so already, consider having an energy audit performed on your home to check for hidden energy leaks.

Sunny Days

Barring differences in humidity, a sunny day will drive up cooling costs faster than overcast days. The culprits are solar rays, which can quickly heat up the house through a process called solar heat gain. The best methods for reducing energy costs caused by sunny days is to add shade via landscaping and awnings, or by adding energy efficient windows or window treatments.

High Humidity

High humidity can increase your energy bill in several ways. For example, one way an air conditioner cools the home is by removing moisture from the air. In humid weather, condensation can form on the A/C coils, causing the unit to run longer and consume more energy. This is one reason high humidity leads to higher energy bills.

Another reason is that humidity makes us feel warmer. Sweat doesn’t evaporate as readily so, body heat isn’t whisked away from the skin. This means we are more likely to adjust the thermostat, and make the air conditioner work harder, so we can keep cool.

While you can’t do anything about muggy Florida weather, you can lower indoor humidity by running fans, using portable or whole-house dehumidifiers, and ensuring your home has proper ventilation.
