Electricity costs on game consoles have soared into the billions with tons of energy being wasted, according to a study (PDF) by researchers at Carnegie Mellon University. However, it doesn't have to stay this way.

The moral of this study: power down when done playing.

According to the research, 68 percent of all game console energy consumed in 2010 happened while in idle mode, which equaled 10.8 TWh of energy and about $1.24 billion in electricity costs. Overall, 1 percent of U.S. residential energy consumption in 2010 was spent on video game consoles, which is an … Read more

A day after being criticized by Greenpeace for its energy practices, Apple said Greenpeace's estimates for power use at the company's latest data center are much too high.

Apple said that its data center now under construction in North Carolina will use about 20 megawatts at full capacity. Greenpeace put the estimate at 100 megawatts.

Greenpeace gave Apple, Amazon, and other companies low marks for locating their data centers in areas that rely heavily on coal and "dangerous nuclear." Those companies also scored lower than competitors, including Google and Yahoo, because they disclose less information on … Read more

A study has found that cars with very high gas mileage are less polluting than electric vehicles charged up in coal-heavy regions.

The Union of Concerned Scientists released a report today called "State of Charge" that finds that on average plug-in cars are less polluting than gasoline-powered vehicles in the U.S. But the greenhouse gases emitted from electric vehicles depends on the sources of electricity.

The study centers on a heated discussion in auto circles. Automakers have sometimes referred to electric vehicles as "zero emissions," which is misleading because most plug-in drivers charge their cars … Read more

Fancy answering the call of nature au naturel but don't like getting too down and dirty? Japan recently saw the opening of a public toilet in a veritable Garden of Eden that designers say is the largest of its kind in the world.

Created by architect Sou Fujimoto, the single, glassed-in cubicle commands a view of cherry, plum, and peach trees in a rural part of Ichihara City, east of Tokyo.

It's located by Itabu Station along the scenic Kominato Railway, and you can hear the old-school trains clunking along as they pass.

Surrounded by a 6-foot wall, the elegant loo stands in a 240-square-yard garden that is being planted with rape blossom and clover.

Sorry guys, it's for ladies only. … Read more

STANFORD, Calif. -- One of the tricks of building a successful company is identifying new markets. So while you might never have known you wanted a digital scent delivery system, a startup called Scent Sciences thinks that's exactly what you desire.

Scent Sciences and dozens of other companies flocked to Stanford University yesterday for the annual Cool Product Expo, a showcase of some of the, well, coolest gadgets, toys, electric cars, and oddball beauty items around. Among the most interesting items on display were 3D Systems' Cube, a personal 3D printer that costs just $1,300 and is being … Read more

Nest Labs today fired back at Honeywell over its patent infringement case against Nest, claiming the thermostat giant is using its patent portfolio to stifle innovation.

The company also hired Apple's former chief patent counsel, Richard Lutton Jr., as it plans for a legal fight with Honeywell in the years ahead.

Founded by former successful Apple engineers, Nest Labs started selling its $250 Learning Thermostat last year and quickly sold out amid rave reviews over its design and ability to automatically set schedules.

Honeywell in February filed a suit claiming that Nest infringed on several of its seemingly broad … Read more

Intel announced its first Atom chip for microservers at a major company confab in Beijing today.

The new Atom, codenamed Centerton, is a system-on-a-chip, which makes it even more power efficient than less-integrated older Atom chips.

Centerton's power envelope -- what the industry sometimes calls TDP or thermal design power -- is six watts. While not as low as the power envelope for Intel's smartphone Atom, six watts is still a lot more power efficient than Intel's more mainstream chips. Those have power envelopes of 15 watts or higher. To date, Atom has been aimed at small … Read more

To a computer company like IBM, plug-in electric vehicles just look like more nodes on the network.

IBM tomorrow is expected to announce a demonstration project with Honda and California utility Pacific Gas & Electric to charge a fleet of Honda Fit EVs without disrupting the grid.

The smart-charging project will also test smartphone and Web-based apps for consumers, giving them an estimate of charge time and location of charging stations.

The power grid as a whole has the capacity to accommodate millions of plug-in vehicles, say experts. But if there's a concentration of electric cars charging at once, … Read more

As the Cleveland Indians play their home games, an experiment in industrial design will be spinning just overhead.

The ball park is hosting a wind turbine that uses a helix-shape tower to squeeze more power out of conventional wind turbines. The structure increases the wind speed, a technique companies have long pursued to lower the cost of wind energy.

The Progressive Field installation is a prototype designed by Majid Rashidi, a professor at Cleveland State University. The 40-foot-high, 18-foot-wide helix turbine will be installed for a year for testing and is expected to generate 40,000 kilowatt-hours a year, or … Read more
