Energy Star Program Needs an Overhaul

Posted by kdawson on from the you-will-sleep-now-and-when-you-wake dept.

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."

    but it can be darn near zero.

    The energy to power a tiny pic and a IR reciever to initiate the power up sequence is less than 100mw This can EASILY be done. They choose not to because it's far easier and cheaper to do it with the main processor. or In most Cable boxes case, simply turn off the screen and led's The comcast cable box really does not turn off, it simply blanks the screen and turns off the led display. This is a pain in the arse for us integration companies as you cant detect power draw to detect if a low grade device is on or off. (high end devices have discreet on and off IR signals or RS232 control)

    The manufacturers want to save $2.95 per device made and refuse to have a discreet "on" response circuit that will allow the set or device to completely power down. but then most manufacturers are too cheap to properly design the hardware for remote control anyways. Not having discreet codes is simply shoddy workmanship.

    The Energy Star Program has needed an overhaul since the day of inception.

    4) Test Methodology: Manufacturers are required to perform tests and self-certify those models that meet the ENERGY STAR guidelines.

    Self-Certify? You've got to be kidding.

      This is just like the IRS... you're expected to report income and deductions and self-certify your filing. If the government thinks you got it wrong, or just picks you out of a hat, they audit. If they allege you cheated, you're on the defensive.
