CIA: Cyberattack caused multiple-city blackout | CNET News.com - 0 views

  •  
    A cyberattack has caused a power blackout in multiple cities outside the United States, the CIA has warned. The SANS Institute, a computer-security training body, reported the CIA's disclosure on Friday. CIA senior analyst Tom Donahue told a SANS Institute conference on Wednesday in New Orleans that the CIA had evidence of successful cyberattacks against critical national infrastructures outside the United States.

Grid blackout threat weighs on renewables take up | EurActiv - 0 views

  • Given a choice between meeting the EU’s target of getting 20% of energy – and 35% of the EU’s electricity mix – from renewables by 2020 or keeping the system stable, “I would rather say that system stability and avoiding blackouts is more important,” she said.

Blackouts and Cascading Failures of the Global Markets: Scientific American - 0 views

  • Cascading failures are an emergent phenomenon of a network, rather than the independent and coincidental failures of its individual components. Although it is true that many banks in the U.S. and Europe simultaneously overinvested in mortgage-backed securities (MBSs) to their peril, positive feedbacks in the global economic system amplified those errors. Bank regulators and macroeconomic policymakers have focused too much attention on the individual nodes of the network (that is, on each bank, and each national economy) without proper regard for the system-wide amplification.

Electricity key weapon in Gaza war - Yahoo! News - 0 views

  • Mahmoud Qassem, a fishmonger, stores his wares on ice overnight in case the fridge shuts down. Suheil Shaban, 62, a diabetic with a bad knee, rarely leaves his ninth-floor apartment — he can't trust the elevator to function. A pediatric hospital director says the generator he relies on is almost out of fuel. ADVERTISEMENT Blackouts dictate the rhythm of life in Gaza these days.

    First time I hear the story of electricity supply being used as a tactical weapon. Probably explains why it is picked up so many times in the blogosphere.

Power cuts a good sign, sceptical South Africans told | Special reports | Guardian Unli... - 0 views

  •  
    The South African government has told millions of people left in the dark by rolling power cuts that have swept the country over the past week, and which are likely to go on for years, to look on the bright side. The blackouts are the result of surging demand for power caused by a booming economy, it says. But as the lights go off more frequently and for longer periods, the national mood has darkened.

Technology Review: Gadgets to Spur Energy Conservation - 0 views

  • Can glorified glow lamps stop blackouts and slash energy costs? Manhattan-based ConsumerPowerline thinks so. This winter, about a thousand participants in the company's energy-conservation program will receive small plug-in boxes that glow red when power demand peaks, urging them to turn off space heaters, defer dishwasher runs, or otherwise save electricity.

    When there is a blackout, your solar power system will probably go out too. That's because most systems are tied to the electrical grid.

Engineering a Smart Grid For Energy's Future - washingtonpost.com - 0 views

  •  
    The process, Current says, lets a utility more efficiently manage the distribution of electricity by allowing two-way communication between consumers and energy suppliers via the broadband network on the power lines. Based on data they receive from hundreds of homes, utilities can monitor usage and adjust output and pricing in response to demand. Consumers can be rewarded with reduced rates by cutting back on consumption during peak periods. And computerized substations can talk to each other so overloaded circuits hand off electricity to underused ones, helping to prevent blackouts.

Mines shut as South Africa faces electricity 'emergency' | Special reports | Guardian U... - 0 views

    South Africa's power crisis today forced the world's three largest gold mining companies to shut down their operations as the government called the rolling blackouts across the country a "national emergency" and threatened to ration electricity.

electricity on/off - 0 views

  •  
    this may make international news for south africa - the "europe of africa" - but it's commonplace in uganda. load-shedding? we don't have it for just a few hours in the afternoon, that would be luxury. no, load-shedding in uganda tends to be on a 24-hour-on-24-off cycle. yes, that means for 24 hours you have electricity, then for the next 24 you don't. there's some elaborate schedule for knowing when load-shedding's going to hit your part of town; sometimes the schedule gets printed in the paper and (almost) always it isn't followed.

Technology Review: Water-Activated Generator - 0 views

  • Hydrogen fuel cells may be decades away from widespread use in cars, but later this year, consumers will be able to buy a fuel-cell generator that's light and compact enough to grab off a shelf during a blackout--or even take on a backpacking trip. The 22-­centimeter-tall generator weighs about two kilograms with an unactivated fuel cartridge. Add water, plug in a device, and the system pumps sodium borohydride solution over a catalyst, freeing hydrogen to power the cell.

ScienceDaily: Best Energy Strategy: Small, Green And Local, Experts Say - 0 views

  • The electricity sector as it currently operates is at the mercy of natural disasters, price fluctuations, terrorist attacks and blackouts. Coupled with other, more long-standing problems such as increasing levels of pollution, growing vulnerability and inefficiency of transmission and distribution networks, and rising electricity prices related to disruptions and interruptions in fuel supply, these challenges add to the need for an evaluation of alternative energy technologies.
