Energy Facts
A well sealed and insulated home saves you money and is more comfortable, clean and energy efficient.

A home with low-wattage, high-output lights saves you money.

 Almost all homes could be more energy efficient and, as a general rule, the older the home, the less efficient it is.

Did you know that you are probably heating and cooling your attic/crawlspace? The average household in California has ducts that leak 30% (to the outside). [California Energy Commission Letter to California Homeowners, August 2, 2005]

Some heating experts claim that an unlit fireplace with a damper open can increase heating costs by as much as 30 percent. Air flowing up or down a chimney could increase your heating and cooling costs up to $500 over the course of just one season.

The US Department of Energy estimates that inadequate insulation in the ceilings, walls and floors amounts to nearly one-third of air leakage, while ducts, fireplaces and plumbing add up to nearly 45%. Leakage from doors and windows amount to 10% each. The solution, for leaky doors windows and many exterior plumbing fixtures, is often as simple as caulking or weather stripping.

Where Does the Most Air Leakage Occur?
Floors, Walls & Ceiling 31%
Ducts 15%
Fireplace 14%
Plumbing Penetrations 13%
Doors 11%
Windows 10%
Fans and Vents 4%
Electric Outlets 2%

An investment in improved energy efficiency has one of the highest returns on investment (ROI). Energy efficiency projects typically see a 20-50% return on investment. Surprised? By dividing estimated annual savings by a project’s cost, you can determine your return on investment. For example, a $1,000 project will save $250 annually, so the return on investment is 250 ÷ 1000 x 100 = 25%.

By stopping drafts in your home, you'll reduce CO2 emissions by 35 lbs. per month.

The U.S. Energy Information Agency estimates buildings currently consume more than 70 percent of the electrical power generated nationwide. What’s more, the Department of Energy calculates 60 percent of a building’s energy use – including heating, cooling, lighting and ventilation – relates to its enclosure (walls, floors ceiling and roof).

An investment in improved energy efficiency is one of the highest forms of political expression.
