As Utility prices continue to climb there is a growing interest in reducing home energy usage. According to the U.S. Department of Energy the residential sector accounts for approximately 21 percent of all energy used in the U.S.
With all of the attention going towards Property Assessed Clean Energy and the proposed Home Star program it is important identify common myths about home energy improvements.
- Install solar first: With all of the excitement around Solar energy (especially in CA) you would think that you're not green until you install solar. Although you will really enjoy watching your meter spin backwards, you could invest in energy efficiency (Solar isn't energy efficiency it's energy generation). Doing some of the basics first like weatherstripping and making sure your duct system is sealed can save you time and money. Read more about "Thinking of installing solar"
- All Insulation is the same: Not true, while we equate insulation to the fluffy pink fiberglass material, there are several other types of insulation that can be more effective if properly installed. Believe it or not if insulation is improperly installed, too compressed or too loose, it will not do its job effectively. It may be worth looking into blown-in or loose fill insulation in places that are appropriate.
- Double-paned windows are always beneficial: While in most cases double paned windows provide increased efficiency, manufacturers are not required to report test data on air leakage. This leakage could come from a poorly insulated frame or due to a loose fit between the frame and glass. It's also important to consider where double paned windows are being installed. If you currently have south facing windows that you rely on for heat in the Winter, that may be lost when you install install double panes.
- Install a tankless water heater: Although a great idea these systems don't always save energy. Since there is no tank to store hot water, tankless systems have a much larger burner to heat water as its needed. Depending on a homes water demand tankless systems may not save energy.
- Zeroing your electric bill means you're using no energy: In many cases, homes rely on natural gas or propane for space and water heating. These can account for more than a third of a homes energy use. This being the case electricity is only part of the battle.
