The U.S. Department of Energy (DOE) has announced it has increased the energy efficiency standards for residential furnaces and boilers.
DOE estimates that these amended standards, which become effective in 2015, will save the equivalent of the total amount of energy consumed by 2.5 million American households in one year, or approximately 0.25 quadrillion (10x15) British thermal units of energy in the 24 years from 2015 to 2038.
"As a nation, we must find better and more ways to both conserve energy and use it more efficiently and productively. These amended standards will not only cut down on greenhouse gas emissions, but they also allow consumers to make smarter energy choices that will save energy and money," said Andy Karsner, DOE assistant secretary of energy for energy efficiency and renewable energy.
DOE has determined that energy efficiency standards for residential non-weatherized and weatherized gas furnaces, mobile home gas furnaces, oil-fired furnaces, and gas- and oil-fired boilers are technologically feasible, economically justified, and will result in significant conservation of energy as a result of increased efficiency.
The total energy savings are estimated to result in cumulative greenhouse gas emission reductions of approximately 7.8 million tons of carbon dioxide – an amount equal to the emissions produced by 2.6 percent of all light truck vehicles on U.S. roads in one year.
