Nissan developing a 10-minute car charger, report says

One of the main arguments against electric cars is that it takes too long to recharge the battery. Even using a DC fast-charger, going from 0 to 80 percent capacity still takes about 30 minutes. But Nissan is working on a new super-rapid charging system that can recharge a drained EV battery in 10 minutes, which could be a game changer for the industry. Nissan engineers and researchers at Japan's Kansai University have created a new capacitor electrode made of tungsten oxide and vanadium oxide instead of the usual carbon, according to an article in Paul Tan's Automotive News. According to an unnamed report, the new capacitor electrode can hold more power and reduce charging time without reducing capacity or voltage.

SolarCity to develop 1.6MW solar project for California school district

The project for the Chico Unified School District was announced along with the launch of SolarChico on Friday, a collaborative community initiative offering residents and businesses discounts on solar power. SolarCity will also donate a portion of the SolarChico program's revenues to the District and conduct free educational solar workshops throughout the community. "Chico Unified School District is excited to support the City of Chico's emissions reduction goals and celebrate our shared commitment to clean energy with our SolarChico Community Program, which we hope inspires more of our community to go solar," said Kelly Staley, Chico Unified School District Superintendent. "SolarChico will generate new funds for the District, which we will utilize for much needed facilities projects."

Small wind heading into boom period, report says

The small wind industry is about to enter a major growth spurt. It is poised to grow from a $255 million industry in 2010 to $634 million industry in 2015, according to a recent Pike Research report. The report attributes a growing interest and expected success in the coming years to the fact that small wind is currently more efficient and, therefore, cheaper on a cost-per-watt basis than solar photovoltaic cells. Because the return on investment can take as little as 5 years to 10 years, depending on area wind conditions, it offers an accessible option to small businesses, farms, and communities even in the absence of state or federal incentives, according to the report. But perhaps the most interesting statistic thrown out there by Pike Research is that it expects the average price of a small wind turbine system to reach $4,150 per kilowatt by 2015.

Q and A about Solyndria and the Clean Energy Industry

In 2009, there were 2.2 million green jobs in America, according to the U.S. Bureau of Labor Statistics. By July of this year, the number was 2.7 million, according to the Brookings Institution. That compares with 375,000 jobs mining coal, producing oil and gas and turning fossil fuels into consumer products.

Lithium-ion batteries for efficient storage of renewable energy and mobile power solutions

Lithium-ion technology is currently more economically and environmentally viable than other existing battery technologies. It will likely be both the present and the future of sustainable storage of renewable energy and mobile power solutions.

Iowa Now Gets 20% of Electricity from Wind

Plug Power Case Study: Wegmans Food Markets, Inc.

The idea of using hydrogen fuel cells instead of lead- acid batteries in the material handling equipment was introduced because of significant benefits offered by the alternative energy power source—increased sustainability, less maintenance requirements and operator self-sufficiency.

Concentrated Solar Power (CSP) - Global Market Size, Competitive Landscape, Regulations & Investment

In 2010, global CSP investments primarily came from Spain and the US. Of total investments in 2010, 59.2% were made in Spain and 28.8% in the US. Spain also recorded the highest number of installations in 2010. Annual CSP capacity additions reached 350MW in 2010 due to the introduction of the FIT scheme.

Investor Interest in U.S. Biofuel Production Set to Soar

Wall Street's big money boys, the Carlyle Group and Goldman Sachs, have already begun discreetly investing in biofuel production in the U.S., but given the size of the recent government's pronouncement, there is still plenty of largesse to go around. Smart investors will be watching developments closely.
