In the latest issue of Science, researchers from Lund University in Sweden have shown how nanowires could pave the way for more efficient and cheaper solar cells.

In a breakthrough that could lead to more efficient and cheaper solar cells, scientists at Sweden's Lund University claim to have identified the ideal diameter for nanowires to convert sunlight into electricity.

Scientists based at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have set a new efficiency record for thin-film copper indium gallium (di)selenid (or CIGS) based solar cells on flexible polymer foils, reaching an efficiency of 20.4 percent

A researcher at the Universidad politécnica de Madrid (UPM, Spain) has patented a nuclear fusion reactor by inertial confinement that, apart from be used to generate electric power in plants, can be applied to propel ships.

The International Renewable Energy Agency (IRENA) on Sunday launched the world's first atlas on clean energy which will offer open-access information on countries' renewable energy potential.

Programme aims to leverage up to €100m of private funds for innovative clean energy technologies.

At about 100 times the strength of steel at one sixth the weight and with impressive electrical conductive properties, carbon nanotubes (CNTs) have promised much since their discovery in 1991.

Until recently LED light bulb manufacturers have struggled to find a solution in the 75 to 100-watt range which successfully replaces the soon-to-be redundant, energy crunching 100 W incandescent bulb in terms of size and brightness.

Prices for solar modules -- the part of solar panels that produce electricity -- will continue to fall, in line with the long-term trend since 1980, according to a survey of experts by Near Zero, a nonprofit energy research organization.

Renewable energy solutions like wind and solar operate on nature's timetable. When the sun blazes or when the breeze blows, power is plentiful -- but not necessarily at the moments when consumers need it, like on a hot, calm summer night.

The sun ejects a continuous flow of electrically charged particles and magnetic fields in the form of the solar wind -- and this wind is hotter than it should be. A new study of data obtained by European Space Agency's Cluster spacecraft may help explain the mystery.

Google announced Wednesday it has invested 200 million U.S. dollars in a wind farm in west Texas, which will become a part of the company's 1 billion U.S. dollars' renewable energy portfolio.

Apple Inc, the well-known manufacturer of phones, desktop, laptop, and tablet computers, has reportedly designed a unique enery storage system for wind energy.

To combat this problem, a team of Penn State researchers is developing more cost-effective ways to prolong battery life.

Under new European Union rules to combat pollution, trucks and buses rolling off assembly lines this year will produce significantly less harmful exhaust fumes.

General Electric Global Research has put together a team of researchers who have accomplished a milestone in the reduction of the price of zero emission buses, by using GE’s new Durathon battery together with a hydrogen fuel cell and a lithium battery.

The Abu Dhabi-based International Renewable Energy Agency (IRENA) said Saturday the six GCC countries' returns through renewable energy integration could hit 200 billion U.S. dollars by 2030.

Stefan Larus Stefansson, Iceland’s ambassador to Japan, recently gave a lecture in Tokyo about the very high geothermal potential in Japan.

California just recently passed the milestone of 1 GW of solar power production (in August). And now it has just surpassed another milestone — it nearly reached that peak August generation level during the week of the Winter Solstice, which is the least-sunny time of the year, setting a new winter solar power generation record.

Energy generation from wind is on target to beat natural gas in 2012, thanks to a mad dash by wind producers to finish projects, as the wind tax credit is set to expire on January 1st.

Surviving without electrical power isn’t something we’re very good at any more. Here in the U.S., if you don’t electricity at home, it’s usually because it’s been temporarily knocked out by a storm or your roommate forgot to pay the bill again.

Renewable energy could fully power a large electric grid 99.9 percent of the time by 2030 at costs comparable to today's electricity expenses, according to new research by the University of Delaware and Delaware Technical Community College.

Princeton researchers have found a simple and economical way to nearly triple the efficiency of organic solar cells, the cheap and flexible plastic devices that many scientists believe could be the future of solar power.

An insight into the properties of fullerene is set to open the door to a new class of electronic acceptors which can be used to build better and cheaper organic solar cells.

The Australian Government announced last week that CSIRO would be leading a new solar research initiative worth over $87 million AUD, an initiative which aims to lower the cost of solar thermal power from 25 cents a kilowatt hour down to 10 cents/kWh.
