Energy Star Program Needs an Overhaul 306

Martin Hellman writes "DeviceGuru.com ran my piece raising questions about the EPA's Energy Star program. For example, an Energy Star compliant TV that claims to draw 0.1 watts in sleep mode appears to do that — but only seems to sleep about 25% of the time that it is 'off.' The other 75% of the time it draws about 20 watts, for an effective sleep power draw from the user's perspective that is 150 times what the manufacturer claims. Based on the observations described, it is also questionable how many PC's really are sleeping when their screens are blank, even if the user has turned sleep mode on. Given the billions of dollars and tons of CO2 that are at stake, this situation demands more attention."

    You do want your TV to respond to your remote control, download it's clock-setting and other background data, and be ready to boot up in a timely manner? Don't ya?

    We can reduce it, but this is something that ain't going to zero.

For something like a microwave that's always displaying the time, you could probably use a battery or rechargeable battery. The battery degrading would probably be the limiting factor there.

            Not so easy, if you're using the ATSC EPG information. It's broadcast; you have to wait for the data to come around, you can't request it. And the data for each channel is available only on that channel. So to get the guide data, you have to scan to each channel sequentially and wait for the data on it; this can take a while. You can't do it while the TV is on (because your tuner is otherwise occupied). It takes significant power to run the tuner. Fortunately, you do only have to do this once every three hours.

Coax networks become unstable if users are constantly logging on and off.

    Suggesting that the testing regime is faulty is a stretch. As with all the other qualms mentioned in the article, you have to question whether the manufacturer provided a proper product, rather than one designed to pass, followed by production of one with "faulty firmware".

    There isn't a whole lot of restriction out there for this type of practice in any standards testing. At least, you can get away with it, most of the time.

      No, not kidding. Like many technical regulations, the cost and expertise required is considerable and the government has little desire to be involved (and less funding). Some large companies can afford to run their own test labs with the necessary equipment and training, but most don't. If you don't have a steady stream of testing, expensive gear is left sitting idle and the test techs' expertise grows stale. That's why independent testing labs are in business: you hire a reputable, qualified lab to do the

    Before going crazy overhauling, let's audit the devices that are out there. Then you can assign marketing labels (Bronze, Silver, Gold, Platinum) in case you can't read the numbers. (Numbers would be watts per day, assuming constant usage)

    Just create something the FCC registration process/database, and let certified labs submit their own engineering reports on the TRUE power consumption. I've never seen any Energy Star audit reports.

      I don't think people would truly understand what it really means to save energy. Simply because you have customers out there who really could care less or think it's too much of a hassle. These are the same people who buy SUVs!!

      They don't either realize or care these little things do add up over time.

      Until we get to the point the electric company will start to impose electric rations as the norm which we in California almost had it happen due to shortages! PG&E been trying to encourage people to sign

        You don't really understand the magnitude of the problem. We can't conserve our way out of growth and we can't conserve our way out of having exceeded generating capacity.

        Absolutely, rationing is coming. Involuntary rationing, like "electric free Tuesdays" and the like. Don't like it? Look to California and the environmental movement - we haven't been building capacity at the rate the country has been importing people. The KWH available per capita has been dropping since the 1960's and it is beginning

      By the Mighty Jagrafess of the Holy Hadrojassic Maxarodenfoe, NO!

      Watt is equal to joules per second. It is a unit of energy per time. Watts or milliwatts would be the correct unit. I blame the kilowatt-hour for starting the metric system down the road to customary.

    There would not be billions of tons of CO2 at stake if we were not generating electricity with coal. Inefficient electrical devices are almost irrelevant to that problem, and pretty much miss the point. Energy efficiency and CO2 production are only weakly related, much like the case with cars, and it is kind of irritating that people so often conflate the two. If everybody in the US switched to commuting in a Prius tomorrow, it would have a negligible impact on total CO2 production (the vast majority of CO2 comes from electricity generation), but it is often sold in those terms. If you get your electricity from nuclear or some other type of green power, there is negligible CO2 impact from having slightly less efficient electrical devices.

    If you want to reduce oil consumption you might buy a Prius, and if you were actually serious you would move to a high-density urban area or lobby cities to allow them to be built.

    If you want to reduce CO2 production you might buy more efficient "green" electrical devices, and if you were actually serious you would lobby for nuclear (and other non-CO2) power plants.

    Part of the reason many environmental policies accomplish so little is that they are largely about symbolism over substance (see: Kyoto). Most people, including many nominal environmentalists, care more about looking like they care than actually solving the problem, particularly if the solution forces them to materially change their lifestyle or preconceptions. It is a cheap and mostly symbolic way to get social approval without actually having to be responsible for enacting useful changes that would actually make a difference. Everyone is so busy trying to prove how green they are that almost no one is actually, well, making the world green.

    • by cdrguru ( 88047 )

      In the US for the foreseeable future, the problem is that base load generating capacity is maxed out. We are not going to build nuclear plants - too many protesters. We are not going to build new high-tension transmission lines - too many protestors. Without either of these a few wind farms aren't going to make much difference.

      The only real solution is to build more coal-fired generating plats. And our new President says he isn't going to allow that.

        I think that problem is very easy to solve. Don't allow any more coal plants to be built, and resolve the shortage using rolling blackouts. Significant opposition to nuke plants will disappear after two or three days. After a week or two, you'll have a pro-nuke movement.

  • I want a little, tiny device, which I'll call the "shutter-offer," that plugs into the wall and has an AC socket that you can plug, e.g., a TV into. When the RMS current passing through the shutter-offer falls below 250 mA for one hour, it opens a switch, and it's as if the TV had been unplugged completely. When you walk into the room and want to watch TV, you push a button on the shutter offer to close the switch again. It's a hassle to remember to physically unplug your TV every time you're done watching

In order to decrease the energy usage of the country we are going to have to really go back to 1850 - you can't "conserve" your way out of the current situation.
