Your Home’s Energy Use

How We Use Energy in Our Homes

Heating and Air Conditioning Typically Accounts for the biggest portion of electricity consumption for a homes utility bill.

To begin you want to locate the areas in the house that use the most electricity. Pie chart shows energy use in a typical home: 34% space heating, 34% appliances and lighting, 13% water heating, 11% electric A/C, 8% refrigerator.This type of approach is known as the wholehouse energy efficiency approach. You can bring in a home energy audit specialist who can determine where the energy is escaping from holes and cracks in the homes ducts and exterior entrance and exit ways. Cracks and openings in windows and door seals are a few easy locations to look at. Single pane windows and attics and walls not properly insulated or updated with Radiant Barrier can also cause substantial energy loss. Many regional utilities in Texas such as Oncor Delivery and Centerpoint Energy provide free home energy efficiency programs to assist in making your home a more efficient and bring needed money savings to the bottom line for your families needs. Everybody could use a little extra money and these tips could give you more then just a little extra. Of course, many of these suggestions you could perform yourself but some of them require a utility or energy expert to take a look at. You can learn more about energy tools and audit’s that can help you in your search for energy savings by checking out the Electricity Guide or the Residential Energy Services Network (RESNET) member page.

Tips On Auditing Home Energy

Creating a Reliable Plan

At this point you have located everywhere energy is being lost in the house. Ask yourself these questions:
