Major electronics maker Toshiba is getting serious about the rooftop solar game, with plans to resell highly-efficient photovoltaic panels made by Bay Area-based SunPower. The two companies just struck a supply deal for 32 megawatts worth of panels in 2010 — enough to power as many as 32,000 homes.
The contract is significant for two reasons. Not only is it expanding SunPower’s global footprint and broadening its portfolio of projects, it also signals increased interest in solar energy in Japan, where Toshiba hopes to launch its residential solar business on April …

Anyone who’s had their laptop or cellphone run out of juice at a crucial moment can attest to the limitations that present power storage methods have on technology, but a product from Aqua Power Systems Japan may indicate an amazing new advancement: the water-powered battery.

At their present capability, NoPoPo (No Pollution Power) Eco batteries have enough power to save lives during a disaster since they can run on the smallest amount of fluid (drinkable or bodily), which means that someone lost in the woods or trapped under rubble could recharge …

Seeking to turn an environmental problem into an economic opportunity, high-tech companies in resource-poor Japan are mining mountains of toxic e-waste for precious materials.
One model project, the sprawling Panasonic Eco Technology Center, sits in lush rice fields an hour’s drive outside of Osaka city.
Inside, workers and humming machines disassemble flat-panel televisions, refrigerators and air conditioners, sorting their metal and plastic components into boxes for recycling.

Toyota plans to lease out 600 of the plug-in hybrids to governments and corporations in Japan, the United States and Europe and gain feedback.

It says it will start selling the plug-in hybrid at home and abroad in two years.

The five-seater has a gasoline-powered internal combustion engine and an electric motor. Increased capacity of the lithium-ion batteries gives it a longer electric-motor-only cruising range. Its plug also allows users to charge the batteries using household electricity.

Japan needs to step up and take a more prominent and visible leadership role at the U.N. climate talks or the conference could end in failure, Japanese and foreign nongovernmental organizations said Thursday.
The Copenhagen conference is supposed to forge a deal on greenhouse gas emissions after the first period of the Kyoto Protocol expires in 2012.
