Long-term natural gas supplies should meet growing demand in coming decades, study finds

Sudden price spikes have led to speculation that the United States is facing a critical shortage of natural gas. But a new study by Stanford University’s Energy Modeling Forum (EMF) concludes that gas supplies are likely to meet growing demand in coming decades, if policy-makers are able to strike a balance between environmental protection and the need for new energy sources.

“Recent volatile natural gas prices do not foreshadow a pending, long-term crisis in future natural gas supplie

New technique could lead to widespread use of solar power

Researchers envision mass-produced rolls of material that converts sunlight to electricity

Princeton electrical engineers have invented a technique for making solar cells that, when combined with other recent advances, could yield a highly economical source of energy.

The results, reported in the Sept. 11 issue of Nature, move scientists closer to making a new class of solar cells that are not as efficient as conventional ones, but could be vastly less expensive and more ver

Using ions to probe ionic liquids

Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory are using a very small and light ion, the electron, to study the structure and dynamics of ionic liquids and how those properties influence chemical reactivity.

Ionic liquids are made of positive and negative ions that pack so poorly together that they are liquids near room temperature. They offer extremely low volatility, non-flammability, new reactivity patterns, and the formation of separate phases that all

Nanoscale model catalyst paves way toward atomic-level understanding

In an attempt to understand why ruthenium sulfide (RuS2) is so good at removing sulfur impurities from fuels, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have succeeded in making a model of this catalyst — nanoparticles supported on an inert surface — which can be studied under laboratory conditions. “If we can understand why this catalyst is so active, we might be able to make it even better, or use what we learn to design other highly efficient catalysts,” sa

World´s Largest Solar Factory Opens In Japan

In this world of increasing worries over dependence on foreign oil, environmental degradation and the vulnerability of power networks, many people are calling for greater use of clean energy alternatives such as solar power. It is encouraging therefore to note the completion of the world´s largest factory for solar panels, built by MSK, Japan´s leading specialist solar manufacturer.

Tokyo-based MSK Corporation has opened the doors to its new production facility located in Nagano, Japan.

Scientists create world’s most efficient light-bulb

Scientists have successfully produced the most efficient light bulb ever – but on the microscopic scale. Researchers at Trinity College, Dublin have discovered a technique which significantly improves the output of light from quantum dots, and also allows their light to be focussed and manipulated easily. Their findings are published today in the Institute of Physics journal Semiconductor Science and Technology.
