Heat water efficiently. Invest in a “tankless” hot-water heater that starts only “on-demand,” or in a solar water-heating system. Besides cutting costs, both can qualify you for a federal tax credit.
Bolster insulation. “Exterior walls, basements, and attics” are usually problem spots. “Fill the cavity any time a wall is open.” Use environmentally sensible insulators, such as “soy-based foams, loose-fill cellulose, and denim,” and opt for the one with the highest thermal resistance, or R-value.
Check kitchen cabinets. Many contain “added urea formaldehyde,” which has been classified as a “human carcinogen.” Find formaldehyde-free cabinetry at Greencabinetsource.org.
Don’t use tainted paint. Many paints contain “volatile organic compounds” that can contribute to smog, as well as a host of illnesses, especially in children. Check out Greenseal.org for a list of certified non-VOC paints.
