Is Seaweed the Future of Biofuel?

As scientists continue the hunt for energy sources that are safer, cleaner alternatives to fossil fuel, an ever-increasing amount of valuable farmland is being used to produce bioethanol, a source of transportation fuel. And while land-bound sources are renewable, economists and ecologists fear that diverting crops to produce fuel will limit food resources and drive up costs.

Chemists Study Mutated Plants, Possibly Better for Biofuels

Genetic mutations to cellulose in plants could improve the conversion of cellulosic biomass into biofuels, according to a research team that included two Iowa State University chemists.

Solar Power Grid Installed at Military Base

A Power Purchase Agreement enabled the Edwards Air Force Base to quickly gain solar power without any upfront costs.

New Wall Display Shows Real Time Energy Usage

There's more to the home energy conservation system designed by Queensland University of Technology industrial design graduate Erica Pozzey than meets the eye.

Italian Researcher Invents Floating Solar Panels

Marco Rosa-Clot, a professor at Florence University, has introduced his new project that addresses the limited-space concerns of photovoltaic panels: The Floating Tracking Cooling Concentrator (FTCC) System, which harnesses small basins and natural and artificial lakes to install PV plants.

World's Largest Fuel Cell Can Power 1,400 Homes

Solvay has successfully commissioned its 1-megaWatt industrial demonstration fuel cell at the SolVin plant in Belgium.

Building Energy Efficient Organic LEDs

Incandescent light bulbs are energy hogs, but many people prefer them for the cozy quality of light they emit.

Dallas-area Habitat for Humanity is First to Install Solar Array

The solar array is the first-ever installed on the office building and ReStore location for any Habitat for Humanity affiliate in the United States.



Sunlight Powering Electric Vehicles

A $2 million award to the Center for Environmental Research and Technology at the University of California, Riverside's Bourns College of Engineering will fund a new project focused on powering electric vehicles from sunlight.

Computer Model Optimizes Biofuel Operations

Research into biofuel crops, such as switchgrass and Miscanthus, has focused mainly on how to grow these crops and convert them into fuels. But many steps lead from the farm to the biorefinery, and each could help or hinder the growth of this new industry.

Scientists Can Now Compare How Efficiently Plants, Photovoltaic Cells Convert Sunlight into Energy

Scientists now have a way to more accurately compare how efficiently plants and photovoltaic cells convert sunlight into energy, thanks to findings by a research consortium that included a USDA scientist.

Massachusetts Schools Install Solar Photovoltaic Electricity Generating System

Ambitious solar initiative at Natick, Mass., schools and buildings will reduce energy consumption and provide educational and learning opportunities.

NREL Help Virgin Islands Cut Fuel Use

The tiny U.S. territory in the Caribbean has just 110,000 residents, all the beach, surf, wind and sun you'd ever want. The downside to this oasis is energy prices that are four to five times higher than are paid in the continental United States.

Sunflower Pattern Inspires New Concentrated Solar Power Plant Design To Increase Power Generation

Just outside Seville, in the desert region of Andalucia, Spain, sits an oasis-like sight: a 100-meter-high pillar surrounded by rows of giant mirrors rippling outward. More than 600 of these mirrors, each the size of half a tennis court, track the sun throughout the day, concentrating its rays on the central tower, where the sun’s heat is converted to electricity — enough to power 6,000 homes.

Check Out the First-ever Portable Fuel Cell Charger That Runs on Water

PowerTrekk, a cutting-edge product that uses clean fuel cell technology that efficiently converts hydrogen into electricity.

Exploring Biogas, An Untapped Source of Clean Renewable Energy

When most people think of clean technology and renewable energy, they think of the two industry stars: solar and wind power. In addition to their promise to replace fossil fuels, they're iconic and aesthetically pleasing. But other clean technology solutions have the potential to shine and make equal, if not greater, contributions to our success in weaning off fossil fuels. One of the most promising of these solutions is biogas.

Electronic Atlas Maps U.S. Renewable Energy Resources

A new geospatial application developed by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL), the U.S. Department of Energy's primary national laboratory for renewable energy and energy efficiency research and development, allows users to easily and accurately map potential renewable energy resources in the United States.

Renewable Energy Sees Explosive Growth in 2011

Renewable energy sources continue to expand rapidly while substantially outpacing the growth rates of fossil fuels and nuclear power.

EPA Chief in Miami to highlight water and energy savings at new green building development

Today, EPA Administrator and Obama Cabinet member, Lisa P. Jackson will travel to Miami to meet with local green business leaders and tour the Brownsville Transit Village, a new environmentally sustainable building project in an underserved community that incorporates water and energy-saving features.

New Solar-powered Classroom Brings Science to Schools in Developing Countries

An innovative project led by a chemistry academic at the University of Southampton is using solar generators to provide IT resources and 'hands-on' science for students in developing countries.
