Energy Star Program Needs an Overhaul
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.
The television in question appears to be actively "on" in the sense that the tuner is on and is sourcing program guide information in standby. When the tuner is not, the consumption is as claimed.
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. I doubt there are many people charged with testing retail devices to see if energy star compliance is maintained. I'd guess that was the major problem.
I record my sleeptalking
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.
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.
