These eight tips will help you cut down on energy costs in your home. The addition of smart meters by San Diego Gas & Electric will help too.

Sometimes, looking out for the environment will cost you extra time, effort and cash. In other cases, however, it can pay major dividends. Improving your home’s energy efficiency, for example, is a win for the environment and your pocketbook. By employing the right combination of cutting-edge technologies and good old-fashioned behavioral changes that fit your budget, your monthly gas and electric bill can be more wallet-friendly. Here are eight places to find opportunities for energy savings in your home.
1. If your furnace is 18 years old, it’s time to buy a new one.
Furnaces built before 1992 are extremely inefficient, wasting more than a third of the fuel they use to get the job done. They are also near the end of their service life. Replace yours with a unit that has an annual fuel utilization efficiency of at least 90 percent. This type of unit will cost between $1,500 and $3,000.
2. Swap out incandescent bulbs for CFLs.
Now’s the time! Don’t let the up-front cost of a CFL bulb prevent you from making the swap. Over its lifetime, a CFL bulb’s operating cost is less than one-third of that of an incandescent. Remember, if you’re replacing a 100-watt incandescent, you need only a quarter of the wattage, so purchase a 25-watt CFL. CFLs cost about $10-$15 per bulb but less if you buy in bulk.
3. Landscape strategically.
Planting a deciduous tree on the southwest side of your home can provide real energy savings, especially if your home has poor insulation and/or leaky windows and doors. In summer, the leaves block the rays that would otherwise heat up your home and, in winter, the bare branches allow the sun to shine through, warming it up. While a fully grown tree will cost you, you can get a 15-gallon deciduous tree for under $100.
4. Insulate your walls and attic.
Proper insulation minimizes the energy you need to heat or cool your home simply by slowing the rate of airflow in and out of the house, saving energy and money. Depending upon the R-value, a measure of thermal resistance, blown-in insulation can cost between 75 cents and $2 per square foot.
5. Fine tune your hot-water system.
You can improve the efficiency of your water heater in three easy steps.
- Turn the temperature setting down from hot to warm. Free.
- Purchase a jacket to insulate your water heater. Kits are available for about $30.
- Swap out the aerators in your sink faucet for low-flow models. $2 per aerator.
6. Rid yourself of phantoms.
Even when the electronic devices in your home are turned “off,” they still draw power when plugging into an outlet. While unplugging devices is a cost-free way to solve the problem, it’s not the most feasible. Simplify your efforts by plugging devices into a surge protector that you can easily switch on and off. A surge protector should cost you $10 or less.
7. Upgrade or replace your windows and seal up your doors.
When it comes to windows, the greatest energy- and money-saving strategy is to replace single-glazed windows with double-glazed. If you’re not ready to swap out your windows, you can still boost their efficiency with weather-stripping, which should also be done around drafty doors. A tube of indoor caulking will set you back about $6, and placing a rolled bath towel (also called a draft snake) at the bottom of leaky doors is absolutely free.
8. Invest in a clothesline.
For the cost of some rope and a couple dozen clothespins, you can dramatically reduce your dependence on your dryer. Inexpensive pulley kits are available at your nearest hardware store for under $10. Not comfortable displaying your unmentionables outside? You can still make energy efficiency gains in the laundry room by washing all loads—even whites—in cooler water and/or setting the dryer to a cooler setting. These tricks are both free.

When considering energy efficiency measures, you should always check with your local utility for rebate programs. San Juan Capistrano’s provider, San Diego Gas & Electric is offering the following rebates for single-family residences:
- Attic or wall insulation, $0.15 per square foot
- Central furnace, $200
- Dishwashers, $30
- Water heaters, $30
- Whole-house fans, $50
It’s also important to note that by the end of 2011, San Diego Gas & Electric will have upgraded all gas meters to smart meters, which is a very handy energy conservation tool. What exactly is a smart meter? It’s simply a high-tech version of your current meter, which, instead of being read once monthly by a utility representative, can send real-time energy use information to SDG&E, which then sends the information to your online customer portal. This allows you to access and monitor your energy use (and see how much it’s costing you) as you are using it. The goal of smart meters is to save time, energy and money and to prevent blackouts. All SDG&E customers will be receiving the smart meters this year.
