New heat-recovery system makes Stanford one of world’s most energy-efficient uni's

At Stanford University in California, it’s normally the Nobel-winning researchers who make the news. But with the commissioning of a novel renewable energy system, the campus’s humble heating and cooling system has grabbed some headlines. Using a first-of-its-kind heat recovery system, and drawing a substantial percentage of its electricity from solar, the university is greening up its operations in a move that will see greenhouse gas emissions cut by 68 percent and fossil fuel use cut by 65 percent.

Electric cars to become mini power plants in California’s energy grid

The California utility, San Diego Gas & Electric (SDG&E), has begun bidding energy resources from fleets of electric vehicles and storage systems into the state’s wholesale power market. The pilot program, one of the first of its kind, is meant to provide insights into how electric vehicles and other kinds of distributed energy resources can make the grid more reliable and efficient.

Modular biobattery plant turns a wide range of biomass into energy

Researchers at the Fraunhofer Institute have developed a "biobattery" in the form of a highly efficient biogas plant that can turn raw materials like straw, scrap wood and sludge into a variety of useful energy sources including electricity, purified gas and engine oil. The new plant design, currently being put to the test in a prototype plant in Germany, is said to be highly modular and economically viable even at the small scale. Read More

Tesla gearing up for release of batteries for the home

The same lithium-ion battery technology that powers Tesla’s electric vehicles will be used to develop a battery for the home, according to a statement by CEO Elon Musk during a recent conference call with analysts. The batteries would be used by homes and businesses to store excess energy generated from solar panels during the day, and drawn from at night when panels sit idle. Read More

Apple looks greener than ever with new renewable energy-powered data centers

We're creating more data than ever before – YouTube receives 300 hours' worth of video uploads every minute – and all of those 1s and 0s have to be stored somewhere. With this in mind Apple's €1.7 billion (around US$1.9 billion) European data centers, which will be powered entirely from renewable energy sources, show a commitment to the planet's future. Read More

CorPower system gives wave power the gears

Harnessing wave power can be a tricky business. It's one thing to build a device that simply moves up and down with the waves, but another to build one that's efficient enough to be cost-effective. Swedish company CorPower Ocean claims to have done just that, however. Its wave energy converter buoys reportedly generate five times more energy per ton of device, at a third the cost of other wave power systems. Read More
