In 1995, a group of agencies in Florida teamed up to bring low-cost solar systems to low-income households so they could save money on their utility bills. [continue reading]
Reducing hot water costs is the most cost-effective way to save money for low-income housing in warm climates. This is one conclusion that can be drawn from a new study on the cost-effectiveness of energy-saving measures for low-income housing in warm climates. [continue reading]
The National Plumbing Standards passed by Congress in 1992 as part of the Energy Policy Act marked a turning point for U.S. manufacturers of toilets, faucets, and showerheads. [continue reading]
