The Transaction Processing Performance Council (TPC) has added a power efficiency metric, TPC-Energy, to its ongoing roundups of speedy transactional processing systems. Hewlett-Packard is the first participant to use the new TPC-Energy specification, submitting benchmark results of four of its systems.\n\n"Energy is an increasing factor in the total cost of ownership" for many organisations, said Karl Huppler, chairman of the TPC. The new benchmark will allow an organisation to judge how energy efficient systems are, as judged by watts per performance.

IBM Research today unveiled a breakthrough method based on a mathematical algorithm that reduces the computational complexity, costs, and energy usage for analyzing the quality of massive amounts of data by two orders of magnitude. This new method will greatly help enterprises extract and use the data more quickly and efficiently to develop more accurate and predictive models.

In a record-breaking experiment, IBM researchers used the fourth most powerful supercomputer in the world -- a Blue Gene/P system at the Forschungszentrum Julich in Germany -- to validate nine terabytes of data (nine million million or a number with 12 zeros) in less than 20 minutes, without compromising accuracy.

Additionally, the process used just one percent of the energy that would typically be required.

"Johns Hopkins materials scientists have found a new use for a chemical compound that has traditionally been viewed as an electrical conductor, a substance that allows electricity to flow through it. By orienting the compound in a different way, the researchers have turned it into a thin film insulator, which instead blocks the flow of electricity, but can induce large electric currents elsewhere. The material, called solution-deposited beta-alumina, could have important applications in transistor technology and in devices such as electronic books."

"A US-based affordable housing developer plans to raise $4bn over the next five years to build and retrofit 750,000 residential, community and commercial buildings nationwide in a bid to make them more energy-efficient.

The not-for-profit Enterprise Community Partners was founded by pioneering urban developer James Rouse, and has seen its profile boosted in recent years after Rouse's grandson, the actor Edward Norton, took a place on the organisation's board."

Roughly half of the 2,164 American adults surveyed last September and October said they had already taken important steps to make their homes more energy-efficient, and a substantial number -- between 10 and 20 percent -- said they planned to take action over the next year. Almost two-thirds of the respondents said that they would like to buy a fuel-efficient car, but over a third said they can't afford one.

Light Blossom is an intelligent LED lighting system that can provide bright light when it senses people walking nearby, and decrease its luminosity when people aren't around. The technology is also energy-efficient and operates off the grid, gathering solar and wind energy during the day to use for light at night.
