Energy Internet and eVehicles Overview
Governments around the world are wrestling with the challenge of how to prepare society for inevitable climate change. To date most people have been focused on how to reduce Green House Gas emissions, but now there is growing recognition that regardless of what we do to mitigate against climate change the planet is going to be significantly warmer in the coming years with all the attendant problems of more frequent droughts, flooding, sever storms, etc. As such we need to invest in solutions that provide a more robust and resilient infrastructure to withstand this environmental onslaught especially for our electrical and telecommunications systems.
Linking renewable energy with high speed Internet using fiber to the home combined with eVehicles and dynamic charging where vehicle's batteries are charged as it travels along the road, may provide for a whole new "energy Internet" infrastructure for linking small distributed renewable energy sources to users that is far more robust and resilient to survive climate change than today's centralized command and control infrastructure.

The sun never sets in the future of high performance computing and networking
When the sun sets on the Communications Research Centre in Ottawa, Canada, the solar-powered computational jobs might be sent across the high-speed connection to the Cybera data center in Calgary, where its still bright and sunny. And when the sun stops shining in Calgary, if the wind is blowing at the wind-powered BastionHost facility in Truro, Nova Scotia, then the jobs could be sent back east.
Most forms of renewable energy are not reliable at any given location. But Canadas Green Star Network aims to demonstrate that by allowing the computations to follow the renewable energy across a large, fast network, the footprint of high-throughput computing can be drastically reduced.
What we hope to explore at a high level is whether the concept has merit, said Martin Brooks, an independent research consultant working on the GSN; Brooks recently retired from the National Research Councils Institute for Information Technology.
If it is successful, said Brooks, the GSN will develop new methods for reducing the carbon footprint of computational resources, and develop a standard that will allow people to innovate in this area.
The advantages of GSNs approach go beyond those conferred by the use of renewable energy sources. Normally, once electricity is generated at large power plants, it must travel large distances via the power grid to reach the computers that power computational science. In the process, a great deal of power `is wasted, dissipated via the resistance of the power lines.
By using the energy where it is generated, the Green Star Networks data centers will also use less energy.
There will probably be some applications that its not appropriate to move, so there are some applications that are not appropriate for this sort of agile environment, Brooks said. The kind of applications that we expect to field will include server structures of different kinds, web servers and other ordinary internet services like that, and well also include some computation intensive nodes.
The key part of the project is the controller, that takes in information about computational load at each node and energy availability at each node and reallocates the computations to keep them running as the various nodes go up and down because of wind and solar variability, explained John Spence, a researcher emeritus at the Communications Research Centre Canada.
The controller will manage GSNs middleware, which leverages existing interoperability projects such as the Open Cloud Computing Interface and Network Service Interface. Interoperability is crucial to the GSN because international partnerships are crucial; in a network with nodes covering every time zone, the sun will always be shining somewhere.
Already, the GSN has formed associate partnerships with i2cat in Spain, HEAnet and NDRC in Ireland, IBBT in Belgium, and ESnet and
Calit2 in the United States.
The project is young, but making steady progress.
Once it is up and running, the GeoChronos science gateway will be among the first to try it out.
