Some people claim that most of our inefficient use of energy will disappear once we “get the price right”— that is, that the price reflects the true costs of supplying that energy. I agree that the price is important, but even when the price is right, the system may still be broken. Here are a few examples.
More than one-fourth of all refrigerators are purchased by people who will not pay for ...
Nothing frightens me more than those model “homes of the future.” I recently visited one of them—the “ConnectedLife” home—at the Consumer Electronics Show (CES) in Las Vegas. The ConnectedLife concept is a joint creation of Microsoft, HP, LifeWare, and many others; the ConnectedLife hardware and software is available at Best Buy. The home sported all of the features that you would expect from these companies: coordination of ...
You bought the new computer for yourself, the game module for your kids, those great new lamps that really brighten up the living room; then, one day you noticed your utility bill had really jumped. Using less heat and shivering through November didn’t cut it. Welcome to the brave new world of energy use in your home. Traditionally, heating and cooling, along with water heating, have consumed most of the energy we use ...
I am looking to purchase window jamb liners that I can install. We are
building an addition and using old wooden windows - we were going to
install weights, but I saw a project on DIYNET that used jamb lines in
old windows. Does anyone know where I can purchase the jamb liners?

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.
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 ...
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 ...
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 ...

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 ...
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 ...
