A survey on cyber security for smart grid communications
A smart grid is a new form of electricity network with high fidelity power-flow control, self-healing, and energy reliability and energy security using digital communications and control technology. To upgrade an existing power grid into a smart grid, it requires significant dependence on intelligent and secure communication infrastructures. It requires security frameworks for distributed communications, pervasive computing and sensing technologies in smart grid. However, as many of the communication technologies currently recommended to use by a smart grid is vulnerable in cyber security, it could lead to unreliable system operations, causing unnecessary expenditure, even consequential disaster to both utilities and consumers. In this paper, we summarize the cyber security requirements and the possible vulnerabilities in smart grid communications and survey the current solutions on cyber security for smart grid communications. © 2012 IEEE

Japan as a Clean Energy Leader
Over the past several decades, Japanâs energy strategy had positioned it as the worldâs leader in clean and efficient electricity production and usage. This strategy, heavily dependent on nuclear energy, was essentially destroyed by one of historyâs largest earthquakes, followed by a tsunami which overwhelmed five nuclear reactors on March 11, 2011. As of April 2012, all of Japanâs 54 nuclear reactors have been shut down and it is uncertain when and how many may be restarted. This paper examines Japanâs options for crafting a new way forward with an energy policy to power the worldâs third largest economy while taking into account the lack of domestic sources of fuel, high government debt, antinuclear sentiments and looming power shortages
