IBM (NYSE: IBM) today announced a research breakthrough in photovoltaics technology that could significantly reduce the cost of harnessing the Sun's power for electricity.

Carnegie Mellon University’s Constantine Samaras and Kyle Meisterling report that plug-in hybrid electric vehicles could help reduce greenhouse gas emissions that fuel global warming, but the benefits are highly dependent on how the electricity system changes in the coming decades.

California electricity and natural gas customers will be charged $600 million over the next 10 years to fund a green think tank, the California Public Utilities Commission unanimously voted on Thursday.

People who want to save energy should always keep an eye on their consumption. The EWE Box offers customers a neat solution: It enables private households to monitor their electricity and gas consumption whenever they want – and save costs thanks to new pricing models.

The Energy Supply Association of Australia (ESAA) says the Government should not force the electricity industry to use selected technologies as it attempts to reduce carbon emissions.

University of Maryland physicists have shown that in graphene the intrinsic limit to the mobility, a measure of how well a material conducts electricity, is higher than any other known material at room temperature. Graphene, a single-atom-thick sheet of graphite, is a new material which combines aspects of semiconductors and metals.

Scientists at Brookhaven Lab have discovered a state of two-dimensional (2D) fluctuating superconductivity in a high-temperature superconductor with a particular arrangement of electrical charges known as "stripes."

Researchers at the University of Minnesota studying bacteria capable of generating electricity have discovered that riboflavin (commonly known as vitamin B-2) is responsible for much of the energy produced by these organisms.

The energy from sunlight falling on only 9 percent of California’s Mojave Desert could power all of the United States’ electricity needs if the energy could be efficiently harvested, according to some estimates.

There is a growing consensus that increased demand for electricity will cement coal’s place in the energy portfolio for years to come. In fact, more than half of the electricity produced in the United States comes from coal.

A discovery by scientists at the Carnegie Institution has opened the door to a new generation of piezoelectric materials that can convert mechanical strain into electricity and vice versa, potentially cutting costs and boosting performance in myriad applications ranging from medical diagnostics to green energy technologies.

South Africa's state-owned electricity company has stopped supplying power to neighbouring countries, triggering a major energy crisis.
