Energy efficiency

PeopleCube, a company that makes software for managing rooms and other resources in buildings, has added energy efficiency features that can gather information to optimize office building energy usage.

The company's Resource Scheduler software lets people arrange the use of conference rooms, shared desks for telecommuters, and equipment for tasks such as video conferencing.

Next month, it will announce Carbon Footprint Tracker, a program that links the company's resource management software to building climate control systems.

The software will do things like turn off the heat or air conditioning in a room when people are not scheduled to … Read more

Can going back to direct current--favored by Thomas Edison--make data centers more modern and energy-efficient?

Start-up Validus on Monday is scheduled to announce the availability of a DC-based electricity distribution system tailored specifically for data centers.

The company, which raised $10 million in venture funding last December, has an initial Fortune 50 company customer that's looking to reduce energy consumption at its corporate data center, according to CEO Rudy Kraus.

The idea of using direct current, rather than alternating current, to reduce power consumption has been around for a long time. The telecom industry relies primarily on DC power … Read more

Online shoppers will soon be able to tell at a glance if computers offer "green" features. Desktop and laptop PCs, as well as monitors, sold online are set to display the EPEAT logo starting early this year.

The label is the closest the electronics industry has come to adopting a third-party, green seal of approval for computers.

EPEAT's bronze, silver, and gold ratings mark electronics offering energy efficiency and sustainable product designs. Equipment that's easily dismantled, made from recycled plastics or using low-toxic ingredients get high marks.

The nonprofit Green Electronics Council runs the EPEAT system … Read more

By 2010, Wal-Mart and its suppliers are going to be a lot more energy efficient.

The retailing giant has set a goal of getting suppliers to increase the energy efficiency of its products by 25 percent in three years. For some suppliers, the standards are a little more stringent. By 2010, the company will only sell Energy Star-rated air conditioners. Flat panel TVs will have to be 30 percent more energy efficient than they are now.

"If we achieved our 25 percent goal just in the U.S. we would save enough electricity to power 3 million homes per … Read more

To curb global warming, we're going to have to crack down on greenhouse gases in a big way, says the American Geophysical Union.

The AGU, an organization that publishes and promotes geophysical research, issued a statement Thursday stating that, to avoid a 2-degree Celsius rise in average temperatures, carbon dioxide emissions will have to be cut in half during the century.

"In the next 50 years, even the lower limit of impending climate change--an additional global mean warming of 1 degree C above the last decade--is far beyond the range of climate variability experienced during the past thousand … Read more

Results from a year-long study on high-tech electricity meters found smart grid technology performed as intended, saving consumers about 10 percent on their bills while easing strain on the power grid.

The Department of Energy's Pacific Northwest Laboratory on Wednesday released the findings from its GridWise project, which tested the use of Internet-connected thermostats and other controls in 112 homes in the Seattle area.

Consumers also tried out appliances, like water heaters and dryers, that were able to automatically change their settings according to signals sent by the utility over the power grid.

The trial showed that consumers are … Read more

Canon printers will soon arrive in stores with a green label flaunting eco-friendly features including energy conservation and recycled materials. The company's "Generation Green" brand will mark Pixma and Selphy photo inkjets as well as the laser ImageClass lines of printers.

"Printers are the one area where you can really improve the environment," said Canon spokesman Justin Joseph. "Their production is a massive undertaking that requires a lot of raw materials, and we've found so many ways to reduce that."

Some inks will be encased in NatureStone biodegradable packs made from limestone … Read more

SunPower and General Electric Energy Financial Services are partnering to build solar power installations generating 8 megawatts in California by the end of the year.

The five projects include what could become the nation's largest solar panel installation on one roof, capable of 2.3 megawatts, at Toyota Motor Sales' Parts Center. Construction is set to start next month.

GE Energy Financial Services is acquiring a majority equity interest in the projects for an undisclosed amount. It will own the systems built and run by SunPower, a maker of high-efficiency solar panels.

The San Jose, Calif.-based company, which … Read more

Porsche announced today that it's developing a hybrid version of the Panamera, a four-door GT car that will debut in a traditional combustion engine version in 2009.

The hybrid system will use a combustion engine, plus an electric motor and an additional clutch, along with a battery pack to store power. The system can switch between the combustion and electric motor, or combine power from both, depending on driving conditions. And although we haven't seen specific technical data yet, this system sounds strikingly similar to GM's "two-mode" hybrid system, which can yield anywhere from zero … Read more
