Energy Star Partner of the Year Awards

Home Energy

On March 21, the EPA and the DOE honored businesses and organizations for their outstanding contribution to reducing greenhouse gas emissions through energy efficiency at the 2007 ENERGY STAR Awards ceremony. EPA introduced the Energy Star program in 1992 as a voluntary market-based partnership to reduce greenhouse gas emissions through increased energy efficiency. Today, in partnership with DOE, the program offers businesses and consumers energy-efficient solutions to save energy, money and help protect the environment for future generations. ...

March/April 2007 Editorial: Surprising Turnabout at Energy Star

Alan Meier

For the first time, Energy Star is decertifying an entire category of product—the programmable thermostat—because it doesn’t reliably save energy (see “Energy Star Changes Approach to Programmable Thermostats,” p. 10). Field studies in diverse climates demonstrated that homes with programmable thermostats used no less—and often more— energy than similar homes without the smart thermostats.† As a result, the programmable thermostat will no longer receive the ...

Off-the-Grid Power Consumption

Off-the-Grid Power Consumption

Home Energy

Question for the Editors Could you please answer a question for me? Living off the "grid", am I better off using flourecent 12 volt dc lights or 120 volt ac flourecent lights through my inverter? Ohm's law seems to say I will use less power through the inverter, with a 26 watt 120 volt light using .2166 amps with a .5 amp inverter draw for a total of .7166 amps, and a 26 watt 12 volt DC light drawing 2.166 Amps. Somehow logic tells me ... [continue reading]

Legislation Would Make California the First State to Ban Incandescent Light Bulbs

Home Energy

Assemblymember Lloyd Levine (D-Van Nuys), the Chair of the Assembly’s Utilities and Commerce Committee, plans to introduce legislation†- the How Many Legislators Does it Take to Change a Light Bulb Act - to ban the sale of incandescent light bulbs in California by the year 2012. Says Levine: "Incandescent light bulbs were first developed almost 125 years ago, and since that time they have undergone no major modifications. Meanwhile, they remain incredibly inefficient, converting ... [continue reading]

High vs Mid-Efficiency Furnaces

Question for the Editors I have a problem with this high efficiency furnace (Carrier Natural Gas Furnace Model 58 MVP) which has been installed in my home for 3 years.† Once each year, and occasionally twice each year, my furnace has shut itself off because the exhaust vent and the air intake have frozen up.† I live in Saskatchewan where we have very cold winter temperatures and accompanying wind making the wind chill a factor.† I have 2 ...

January/February 2007 EditorialóCompliance: Following the Letter (and the Spirit) of the Law

Home Energy

Several unrelated matters related to compliance with energy efficiency regulations crossed my desk recently (see “Caveat Emptor,” p. 12). These incidents illustrate that compliance—or failure to comply—with a regulation is not always objective. Indeed, one could say that there is a spectrum of “compliance.” First there is outright fraud. This was probably the case where the Federal Trade Commission (FTC) ordered an insulation company to desist from its ... [continue reading]

EPA Introduces WaterSense Labelling Program

Home Energy

America's water supplies are precious but not unlimited. Every drop counts. Water is the lifeblood for families, communities, and ecosystems. Using it efficiently is everybody's business. Increasingly, water and wastewater utilities, industry, and agriculture are relying on water efficiency as a low-risk and low-cost option to help meet growing demands. Faced with rising demands for water and an increased need for wastewater treatment, it's just common sense to use the water that we have as ... [continue reading]

The Cost Of Air Tightening May Go Up by Max Sherman I grew up in an old, leaky house. I’ll bet a lot of Home Energy readers did too. When the wind blew, you could almost feel it inside. No one worried about getting enough ventilation then, though. After all, the Latin root of “ventilation,” ventilare, means to expose to the wind. Houses were said to breathe. Despite the back-to-nature feel ... [continue reading]

Partnerships for Home Energy Efficiency a Success in its First Year

Home Energy

Formed in 2005, Partnerships for Home Energy Efficiency (PHEE) is a joint effort by the US Department of Energy, the US Environmental Protection Agency and the US Department of Housing and Urban Development to reduce the energy consumption of the average U.S. home by 10%† by 2015. Currently, US residents spend more than $160 billion a year to heat, cool, light and live in their homes. US residences account for approximatley 21% of our country's energy use, and contribute ...
