US-built supercomputer named fastest in the world

Called Summit, it is set to solve problems in areas of energy and artificial intelligence

California computers to become energy efficient

California could become the first state to adopt computer energy efficiency rules. The California Energy Commission (CEC) aims to adopt a set of energy saving guidelines by 2018. It estimates the average upfront cost of a computer will rise by $18 (£13.8) but suggests customers will save around $75 (£57.6) in energy savings over the lifespan of […]

“Electronic blood” will fuel and cool computers of the future

IBM has unveiled a prototype of a new computer (pictured) powered by what it describes as “electronic blood”. It’s hoped it could lead to more energy efficient computers in the future. The team working on the project in Zurich took inspiration from the human brain, which is both smaller and more powerful than any of […]

Middle East energy “more vulnerable” to cyber attacks

The Middle East’s energy sector is “more vulnerable” to cyber attacks than the rest of the world, it was claimed this week. There’s “insufficient” awareness of the threat from government and firms, little investment in cyber defence and unlike the US and Europe, no cyber security strategy is in place yet, according to an expert […]

Power firms ‘at risk from cyber attacks’

Power companies are increasingly at risk from cyber-attacks because their computer security is stuck in the last century, a British security firm claimed this week. The warning comes after the US government told thousands of firms to boost the protection of computers which operate power plants and other utilities. This was prompted by a survey […]

£1.3 billion spent on hidden energy costs

UK consumer pay up to £1.3 billion every year on hidden energy costs when they leave their television and computers on standby, a new report suggests. The ‘Powering the Nation – household energy using habits uncovered’ study measured and monitored the day-to-day use of electricity in households – when it was being used, for how […]

University saves £27k on computer energy use

Staffordshire University has saved around £27,000 a year by making its computers more energy efficient. It introduced software letting it centrally control and reduce the energy used by the 4,000 PCs on its network by 60%. When switched on, the average PC draws 65 watts of electricity, 3 watts when suspended (standby), and 1 watt […]
