What is Energy Efficiency?

Being energy efficient means using energy in smarter, less-wasteful ways. From using different light bulbs and insulation to using programmable thermostats and sealing your windows and doors, there are many ways to improve the efficiency of your home and workplace while keeping your electric and heating bills low.

Energy Efficiency Programs by Texas Electric Utilities

In Texas, most electric utilities participate in energy efficiency programs. The utilities like to promote energy efficiency, because it helps keep the demand for electricity at a manageable and cost-efficient level.

When the population grows, more people need electricity. The need for electricity is also called "demand." The amount of electricity sent over the wires by the utilities is called "load." So, when the population and demand for electricity both increase, it is called "load growth."

If the utilities can continue sending the same amount of power over the wires instead of having to increase it as the population grows, that means that utilities and consumers are all being energy efficient.

The Legislature and the Public Utility Commission set the goals for the utilities to meet.  The utilities meet their energy efficiency goals by providing incentive money to energy service providers such as home energy auditors, air conditioning companies, insulation companies, and even home builders to provide energy efficiency services to you.  Some energy service companies may then pass that discount to you to match the incentive that the utility pays the company.  Before having any energy efficiency measure installed in your home, you should ask the energy service company if there is a discount based on the utility’s incentive to the energy service company.

Some electric cooperatives and municipal utilities offer energy efficiency programs as well. Some examples are:

CPS Energy

Austin Energy

Pedernales Electric Cooperative

How do I participate in a utility's energy efficiency program?

Before having any energy efficiency measure installed in your home, you should check with 2 or more energy service providers to get the best price for the service. An energy service provider can be a home energy auditor, air conditioning company, insulation company, and even a home builder. You should ask the energy service provider if there is a discount based on what incentives your utility may be offering. You should also ask whether there is a fee to audit (check) the home to find the energy efficiency measures that will save you the most energy and money.

One example of a home energy audit is when a professional home energy auditor checks your home for air leakage. They do this by closing all the windows and doors and then pumping air throughout your home to check if air is leaking to the outside. If leaks are found, they can recommend that certain measures be taken to fix the leaks, such as caulking around windows and replacing weatherstripping around doors.

Prices for energy audits vary, depending on the type of audit requested. You could pay anywhere from $79 to $400 for a home energy audit. You should first ask your utility if they provide free or discounted energy audit programs before paying full price. It's also important to shop around. If you like to handle home repairs yourself, you may only need a basic inspection to get the information your need.

Are there any energy efficiency programs for low-income customers?

If you meet certain income requirments, you may be able to have free energy efficiency measures done on your home. This is offered through the Public Utility Commission's Hard-to-Reach Standard Offer Program. Ask your utility or retail electric provider about the standard offer program available in your area.


The Texas Department of Housing and Community Affairs’ Energy Assistance Section administers two federally funded programs through local subrecipient agencies. Application intake, income verification, and all client services are handled by the local agencies.

These programs are the Comprehensive Energy Assistance Program (CEAP) and the Weatherization Assistance Program (WAP). CEAP provides heating and cooling home energy assistance. WAP provides weatherization services.

If you need help with utility bills, find the local CEAP service provider nearest you. You may also call toll free (877) 399-8939 between 8 a.m. and 5 p.m., Monday through Friday. The toll free number will connect you with the CEAP service provider in your county. Please use a land-based phone when dialing the toll free number. If using a cell phone, please dial  2-1-1, and the operator will direct you to your local service provider.

If you need help weatherizing your home , find the local WAP service provider nearest you. You may also call toll free (888) 606-8889 between 8 a.m. and 5 p.m., Monday through Friday.

8 Tips For Light Bulb Shopping

New standards give consumers new lighting choices that are 25-30 percent more efficient than the decades-old, incandescent bulbs. Contrary to reports, incandescent lights are NOT banned—they are simply becoming more efficient.

Not only will these new light bulbs cut your energy bills, they’ll improve the environment by
reducing emissions from power plants due to less energy consumption.

Here’s what you need to know the next time you are looking for a new light bulb:

Halogen incandescents—These look like the older bulbs, but use 25-30 percent less energy
and can last up to three times longer.  A new 72-watt, energy-saving, incandescent bulb,
which replaces the old 100-watt, bulb will cost about $1.50. But each one will save you about
$3.00 over its lifetime.

Compact fluorescent lamps—CFLs are your best value. They use about 75 percent less energy
than older bulbs and last up to 10 times longer. A $2.00 CFL will save you up to $50 over
the bulb’s lifetime.

Light-Emitting Diodes—LEDs will last up to 25 years (based upon usage of 3hr/day) and
save 75 percent, or more, in energy costs—but they will cost you more to buy than the other
choices. Even though LEDs today cost around $25 per bulb, they’ll still save you around
$150 over their 25-year lifetime. As they become more common, you can expect their
prices to go way down.

In other words, if you are trying to replace your old, inefficient, 60-watt, incandescent bulb with a
bulb that gives off the same amount of light, look for one around 800 lumens.

  • Read the package: A Lighting Facts label will be required on packages for most bulbs manufactured after January 1, 2012. As shown below, it will tell you the brightness in lumens, estimated yearly energy cost, expected bulb life, light appearance (“warm” or “cool”), wattage (energy used) and whether it meets Energy Star standards (See #8). The label will also tell you if the bulb contains mercury.
  • The Mercury Question: CFLs contain a small amount of mercury (typically less than 3 mg.) to produce light. Three milligrams is an infinitesimal amount compared with old thermometers, which contained  500 mg of mercury. Even with the small amount of mercury, CFLs actually reduce mercury in the environment because they reduce the amount of mercury produced by power plants. Intact and in use, CFLs release no mercury. However, like nearly everything else in your house, they need to be properly recycled and cleaned up, if broken. Many retailers recycle CFLs for free.

Go to for more information.

  • Look for the ENERGY STAR label: CFLs and LEDs with the Energy Star Label meet specific performance standards and are subjected to independent testing to help ensure a high level of efficiency and quality. Beware, not all lights qualify. Check out: for more info.
