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.

Green IT solutuions: energy efficiency versus purchasing renewable power?
Of course, the big problem with RECs, or renewable energy resale is its cost. It can be substantially more expensive than dirty power. So purchasing RECs is really an indicator of an IT organization’s true commitment to becoming green. An alternative approach is to acquire your own renewable power is by building windmills on site or relocating IT equipment to a renewable energy sites. For example ecotricity (www.ecotricity.uk) in the UK has a novel business plan where they will build a windmill at a data center at their cost, in return for a long term contract for the power delivered from the windmill. Other organizations such as MIT and UoMassachusetts are looking to relocate their computing and cyber-infrastructure equipment to remote data centers powered by local hydro electric dams and/or windmills. The challenge with this scenario is the reliability of power. How can you build a reliable IT infrastructure when you have intermittent power sources such as wind mills, solar panels, etc? This is where clouds, grids and virtualization connected with high speed networks can play a critical role. Computing and data jobs can quickly be moved from site to site depending on the availability of local renewable power. This is the essence of CANARIE’s Green IT program. And as illustrated by the recent paper from researchers at MIT and CMU can save up to 40% on energy costs alone.
Even for consumers, using renewable power can be much simpler way of reducing their footprint than through buying energy efficient devices. According to the IEA, consumer IT devices use more power in aggregate than all traditional appliances combined in many homes. A lot of this power consumption is taken up by “vampire” loads when devices are in standby mode such as wall chargers, TVs, set top boxes, etc. A simple solution would be for the consumer to install a small solar panel and/or wind turbine and power all these vampire loads with a “multiplexed power” system using the existing household copper wiring. A vampire power network could use something like a 400 Hz power frequency which would be filtered out by traditional AC devices but could easily power appropriately modified AC/DC converters, chargers, switching power supplies, etc – BSA]
