Panasonic Achieves 25.6% Solar Cell Efficiency

Panasonic Achieves 25.6% Solar Cell Efficiency

Panasonic Corporation announced that it has achieved a conversion efficiency of 25.6% (cell area: 143.7 cm²) in its HIT (heterojunction with intrinsic thin layer) solar cells, a major increase over the previous world record for crystalline silicon-based solar cells. The previous record for the conversion efficiency of crystalline silicon-based solar cells of a practical size (100


Solar Fuel Cell Converts Biomass to Electricity

Researchers at the Georgia Institute of Technology have developed a new type of low-temperature fuel cell that directly converts biomass to electricity with assistance from a catalyst activated by solar or thermal energy. Although low temperature fuel cells powered by methanol or hydrogen have been well studied, existing low temperature fuel cell technologies cannot directly use


San Francisco Announces 0-50-100 Plan

San Francisco says it is closing in on the goals of its 2004. Climate Action Plan and released its strategy to meet the more stringent goals it set for 2025. This “shows that it is possible to reduce the harmful emissions that cause climate change at a citywide scale,” says the website, providing a model for other cities to follow. San


Disney: Discontinuing Pro-Fracking School Tour

Sometimes, the actual news seems more like an Onion parody. This is a great example. Radio Disney has withdrawn from a pro-hydraulic fracturing school tour backed by the oil and gas industry. Al Jazeera America reports that the program, called Rocking in Ohio, visited 26 elementary schools and science centers across the state last month. The tour, led by


RIP: Ontario MicroFIT Program?

The Ontario MicroFIT program is a keg about to run dry. Nobody knows if there’s another keg in the cellar. The Ontario Power Authority isn’t saying. There are encouraging signs, but past experience has taught us to be pessimistic. We’ve been here once before. In October of 2011, following a provincial election, the program was


Nelson Mandela and Climate Change

Former South African President Nelson Mandela, who served 27 years in prison for anti-apartheid activities and led his continent into a new era, has died at age 95.  He was born Nelson Rolihlahla Mandela in Transkei, South Africa. He was arguably the greatest man of our times and one of the greatest men history has


Chile: The Next Renewable Energy Rock Star?

For years there has been a lot of talk aboutclean energy in America, China, and Europe, but a new player has entered the field of play: Latin America.  Eager to kick their dependence on coal, oil, and other fossil fuels, these nations are beginning to ramp up their investment in renewable power.  Whereas Brazil used to


127 Countries Greenlight Renewable Energy Policies

A total of 127 countries have enacted policies to encourage the development of renewable energy projects this year found the Worldwatch Institute’s latest Vital Signs Online report. According to the Worldwatch Institute, support policies for renewable energy technologies have increased dramatically over the last decade. Starting the mid-200’s policies focused on deployment of renewable energy


The SunShot Initiative: This Could be Big

There’s fresh evidence that the SunShot Initiative, despite being virtually ignored by a mainstream media more interested in faux scandals like Solyndra, might be the most important thing the Obama administration is doing to hasten the U.S. transition away from fossil fuels. According to new research, if the program hits its goal of bringing the price

Solar Power: Glass Half Empty or Half Full?

GE and First Solar announced earlier this week an important step towards consolidation of the solar industry that will result in the loss of a new solar manufacturing facility  in Colorado and, potentially 350 jobs.  Clearly the announcement is frustrating for Colorado, a state we featured in EDF’s Clean Energy Economic Development Series, which highlights


Here Come the Solar Suburbs

Suburbanites: Please buy electric vehicles and put solar on your rooftops — the cities of the future need you! According to new research out of the University of Lincoln in the U.K., a solar-powered suburb filled with EV drivers has the greatest potential for not only powering its own needs with clean energy, but also


Oy Vey: Cost of Climate Change is $60 TRILLION?

What’s the real imperative of the migration to renewable energy and cutting back our consumption of fossil fuels via efficiency and conservation?  Might you say: Climate change? We’ll, that certainly one good answer.  Of course, there are half a dozen others:  dealing with peak oil, health issues, ocean acidification, the loss of biodiversity, human hostility,


A Sustainability Incubator for Cities

While there are lots of incubators for startup companies to help them get their business off the ground, for the first time there’s an incubator that helps cities learn how to implement sustainability initiatives. Portland State University has selected the first “class” for its “Urban Sustainability Accelerator,” a year-long program designed specifically for smaller and mid-sized US cities. “Today,
