AGA has conducted an extensive analysis on the emissions and energy costs of home appliances, and the results are impressive. We’ve found that the direct use of natural gas in residential appliances results in lower energy production, lower consumer energy bills and lower greenhouse gas emissions when pitted against fuel oil, electricity and propane. The measurements were taken on a “full-fuel-cycle” basis, or, from the point of production to the end-use, accounting for energy lost along the way. The full-fuel-cycle measurement is really the most logical way to measure energy efficiency and carbon output – otherwise consumers aren’t getting complete information.
Consider that where an electric resistance water heater produces 3.1 metric tons of CO2 per year, a comparable natural gas water heater produces only 1.5 metric tons. And natural gas retains about 90 percent of its useable energy from the point of production to the burner tip in the home. In contrast, only about 30 percent of the energy produced to satisfy the electricity needs of consumers is retained in the process of energy production, conversion, transmission and distribution.
Homeowners using natural gas are not only doing their part to reduce greenhouse gas emissions but also can significantly reduce their energy bills – on average, 34 percent lower than oil homes, 30 percent lower than all-electric homes and 45 percent lower than propane homes.
More and more, Americans are striving to find ways to save money while making eco-conscious choices in their everyday lives. Using the full-fuel-cycle parameters, the facts are clear: natural gas is the cheaper, greener choice for appliances.
