Someday I’ll install solar panels on my roof and watch my electric meter slow to a stop then start whirling backwards as I generate more juice than I can use. On that day I will become an energy producer and seller (to my electric company), not just a consumer. But that day is still years away; I’m waiting for the average $35,000 pricetag (that’s after a $20,000 tax rebate) for the panels to come down.
In the meantime I’ve discovered three new products that will take a big bite out of my utility bills and make me less of an energy guzzler.
Solar Water Heaters. Tapping a free and renewable energy source, solar water heaters provide the most cost effective means of heating the water in your home. The systems use solar collectors (mini panels installed on your roof) and insulated storage tanks, and are either active, using circulating pumps, or passive, without. Though some small households in the sun-drenched southwest are an exception, most homes require the backup of a gas water heater to kick in on cloudy days and for excessive water use. The system is initially more expensive than a conventional water heater to purchase and install, but you will immediately start saving between 50-80% of your water heating cost and will make up the difference in a few years.
LED lights. Light-emitting diode, that is. By now we all know that CFLs, compact fluorescent lights, use one fourth the energy of incandescent lights and last six times as long. But did you know that LEDs use one tenth the electricity of the old bulbs and last forty times as long? Which is why they cost around $55 a piece, vs. $3 for a CFL. However, over the long life of an LED you will realize big savings, especially as energy costs soar. But there are a few drawbacks: LEDs provide directional light, which is great for task lighting, but not good for table and floor lamps. And you may have to save up to invest in your first bulb.
Energy-Monitoring Smart Homes. For years home automation has helped homeowners dim lights, lower the thermostat and time sprinklers. But now some smart homes track energy usage for you in real time, like an electric meter brought inside. When the home exceeds a certain level of energy use, the system can be programmed to close shades, reduce lighting levels and moderate the thermostat. These monitors can prevent your house from ever going on an energy binge again. Home automation systems are a sizable investment, starting around $3,500. If you are determined to lessen your carbon footprint, installing an energy whistleblower might be a good investment.
