A New Standard for Cell Phone Chargers

Wed, 02/18/2009 - 14:20 -- MrGreen

February 18, 2009 - Earlier this week, in Barcelona Spain, 17 leading mobile phone service providers and manufacturers announced that they are committed to a new standard for a universal charger for mobile phones. The initiative, led by the GSMA (Groupe Speciale Mobile Association), has set a target date of 2012 for having a universal charging solution (UCS) available that will use Micro-USB as the common universal charging interface. UCS chargers will include a 4-star or higher efficiency rating, which is up to three times more energy-efficient than an unrated charger.

Reducing Standby Power Waste in the Great White North, Eh?

Tue, 02/17/2009 - 15:26 -- MrGreen

February 17, 2009 - It was a very cold and white day when I arrived in Toronto last Friday to attend Natural Resources Canada’s (NRCan’s) Standby Power workshop. The Office of Energy Efficiency wants to amend the country’s Energy Efficiency Regulations which first came into effect in 1995. The purpose of this meeting was to give stakeholders an opportunity to hear firsthand about the mandatory standby power performance standards that are being proposed.

Green Goes Glamorous

February 10, 2009 - Energy efficiency awareness is getting some help from Hollywood as celebrities make public service announcements calling for energy conservation. One such personality is Cameron Diaz who recently came out with two short videos, one calling for the use of power strips to shut off computers and another asking people to unplug their cell phone chargers when not in use.

Climate Savers Promotes Greater Efficiency for Computers

Fri, 02/06/2009 - 09:27 -- MrGreen

February 6, 2009 - Since ENERGY STAR's new computer spec (V 5.0) has been approved and is scheduled to go into effect in July, it made me think of another energy efficiency initiative gathering momentum and targeted at computers (and servers): Climate Savers.

No TV Left Behind?

January 13, 2009 - Is it time for a mandatory energy efficiency standard to force our new large screen televisions to go on an energy diet?

Video Games are Now on the Radar

Fri, 12/19/2008 - 13:23 -- MrGreen

December 19, 2008 - When we think of energy sucking electronics, things like hotplates, space heaters, and the incandescent light bulb often come to mind. We like to assume that modern state-of-the-art electronics are more energy efficient. Because of this, newer electronic devices, such as video game consoles, manage to slip beneath the radar for a time. But now that time is up.

Green TVs for a White Christmas

Mon, 12/01/2008 - 10:52 -- MrGreen

December 1, 2008 - On my way to work today, I heard that, as a consequence of the down economy, more people are staying at home. That makes sense. It also means that more people will be using their televisions more for watching broadcast programs, DVD movies, video games and other multi-media functions. This could be an energy nightmare since some large flat panel TVs have been known to consume up to 500 kWh per year, as much energy as a refrigerator.

More Stars per Bars for Mobile Phone Users?

Mon, 11/24/2008 - 14:56 -- MrGreen

November 24, 2008 - This month, a group of major mobile phone suppliers have taken a step that goes beyond any worldwide agency’s current or proposed no-load power consumption specs by announcing a new tighter no-load rating system for their chargers.

ENERGY STAR Gets Serious about Games

Thu, 11/13/2008 - 09:31 -- MrGreen

November 13, 2008 - Video games have provided tons of family fun over the last few years, even allowing some of us rock star wannabes to perform center stage (well, center living room stage). But these boxes of fun have also been shown to be large energy consumers, even in their idle mode. One study showed recently that when left idle, certain game boxes can use over 100 W waiting for someone to come back in the room and take the controls. And some games consume almost 10 W even when they enter into their standby mode.

EPS Voluntary Efficiency Specs May Find Harmony… Again

Wed, 11/05/2008 - 09:56 -- MrGreen

November 5, 2008 - What started out as a coordinated effort by worldwide agencies to harmonize around ENERGY STAR’s tier 1 EPS spec in 2005 has, in the past eighteen months, morphed into a patchwork quilt of different nameplate power groups sporting various conflicting minimum average efficiency and no-load power consumption levels for those groups.
