Wii Crushes Other Game Consoles in Energy Efficiency

wii-efficient
A new report from the Electric Power Research Institute looked at the energy consumption of the three most popular video game consoles -- the Nintendo Wii, Microsoft Xbox 360 and Sony Playstation 3 -- and the Wii was far and away the most energy efficient, using one-sixth the power used by the other two.

The researchers played one hour of Madden NFL 11 on each system and then recorded the power consumed.  The Wii used 13.7 watts, the Playstation used 84.8 watts and Xbox used 87.9 watts.  The reason for the huge disparity between the Wii and the other two is that the Playstation and Xbox feature much higher quality graphics and more powerful processors.

Over the course of a year where the user does some serious gaming (5 hours, 45 minutes a day), the Wii consumes energy equivalent to a flourescent light fixture, where the other two consume energy equivalent to a washing machine.

So, if you're currently in the market for a new game console and energy efficiency ranks higher on your required feature list than the quality of the graphics, the Wii is obviously the best choice.

Starbucks Saves Millions on Energy Bills with LED Lighting

starbucks-leds
On a light-by-light basis, changing from incandescent to LED only makes a tiny difference in energy consumption and cost, but when you're talking about retrofitting a large building like the Empire State Building or replacing bulbs in thousands of Starbucks stores, the energy savings can be huge.

That's just what Starbucks has found now that the replacing of incandescent and halogen lights in 7,000 stores in the U.S. and Canada has been completed.  The company's Director of Environmental Impact said that the program is on target to cut lighting energy consumption by 80 percent.

The good folks at Greenbiz did the math and figured that each 1,000 square foot store was saving $600 a year and reducing CO2 emissions equivalent to 10 barrels of oil.  The lights also cut total store energy consumption by 7 percent.

LEDs were installed in the sitting and beverage areas where the color of the light was most important and CFL bulbs were installed in the rest of the store.  The energy and cost savings calculated were for the LED lights alone.

Cloud Computing Could Slash Data Center Energy Use by Over One-Third

cloudes
As the energy used by data centers around the world rapidly grows, so do the emissions they're responsible for -- currently 2 percent of global greenhouse gas emissions.  A new report issued by Pike Research indicates that cloud computing could make a huge dent in the energy used by data centers and the resulting emissions.

The study by Pike has some very positive figures.  Energy use by data centers could be reduced by 38 percent by 2020 if companies continue to switch over to cloud computing at the expected rate.  With that drop in energy use, emissions could be cut by 28 percent from 2010 levels.  Energy costs could drop from $23.3 billion in 2010 to $16 billion in 2020.

There's still a lot to figure out when it comes to the exact benefits of cloud computing though.  Greenpeace issued a report this year saying that emissions from cloud computing could triple by 2020, so the switch will need to be combined with other energy-saving efforts. But it's clear that cloud computing is a far better than the current, server-heavy, power-hungry data center model.

New Database Rates Energy Efficiency of Ships

shippingefficiency
A new online database, ShippingEfficiency.org, gives efficiency and emissions ratings for 60,000 ships worldwide to push fleet owners to start using cleaner and more efficient ships.

The project was created by billionaire Richard Branson to empower exporters, importers and even cruise-vacation-goers to choose the most efficient ships to do business with.  The database lists engine size, type of ship, energy efficient features, emissions and other information about each ship along with overall ratings based on those facts.

The builders of the database have great expectations for the project.  They expect it to reduce shipping CO2 emissions by as much as 25 percent.

The shipping industry has a very large carbon footprint and has been hard to regulate because shipping is a global business and national or regional restrictions are hard to enforce.  The database is aiming to solve the problem by putting the power in the hands of businesses and consumers to affect change, instead of governments.

The 60-Watt Replacement LED Bulb Arrives

12wattLED

For years we have been watching as LED technology has improved and the cost of LED replacement bulbs has gotten lower and lower. Compact fluorescent bulbs have become commonplace, which has been instrumental in saving energy and lowering electricity costs for millions of consumers. But still, we've been waiting for LEDs to reach the point where they start being widely used. And now, it looks like that point may be here.

By the middle of 2011, a new 12-watt LED bulb from Osram Sylvania is scheduled to be available from all Lowes stores.

The Osram Sylvania Ultra A-Line LED bulb produces 810 lumens. This compares quite well with a standard 60 watt bulb (the one I checked is listed at 830 lumens). The LED bulb uses 12 watts, versus the 60 watt incandescent, wich is an 80% energy savings. And the LED bulb should last 25 times as long as a conventional bulb.

The biggest remaining question will be consumer acceptance. Does the LED bulb provide an adequate distribution of light, without the "hot spots" and dim areas characteristic of some earlier LED bulbs? And, is the color rendering of the LED good enough to make it an acceptable substitute for an aincandescent bulb? The A-line bulb has a color temperature of 2700 Kelvin and a color-rendering index (CRI) of 91. (An incandescent bulb has a perfect value of 100.) Most fluorescent bulbs have a CRI ranging from the low 50s to the high 80s, so the quality of the light should be quite good.

LED lights may have some end-of-life issues with circuit board materials, as do compact fluorescent bulbs, but, especially with RoHS regulations in place in many parts of the world, those are minor compared with the question of mercury in compact fluorescents. Of course, it's not a problem if the CF bulb is recycled (and more and more places are now taking those bulbs for recycling so that is becoming less of an issue, as well). And the total amount of environmental mercury is lower when considering the amount of mercury put into the atmosphere by burning coal to produce all the additional electricity that a conventional incandescent bulb requires as compared to the amount that would be spilled if a bulb was broken rather than being recycled, so concerns over CFLs should already be pretty well settled.

The 8 watt A-Line bulb is around $20 and is available right now. The 12 watt A-Line bulb should be in stores in the first half of 2011.
