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.

Excellent report on Internet Data Centers and Global Warming
This is a good comprehensive report but surprisingly misses the entire subject of Khazzoom-Brookes postulate (aka Jevons Paradox) which refutes the entire argument of energy efficiency. Khazzoom-Brookes have effectively demonstrated that improved efficiency actually results in increased energy consumption as it decreases the overall cost of a product or service and therefore increases demand.
For more details please see my blog on energy efficiency and data centers as well a paper prepared in part for the OECD on this subject. The OECD is also having a workshop where this subject will be discusses in Denmark May 22-23.--BSA]

Some excerpts from the McKinsey report
For many industries, data centers are one of the largest sources of Greenhouse Gas (GHG) emissions. As a group, their overall emissions are significant, in-scale with industries such as airlines. Even with immediate efficiency improvements (and adoption of new technologies) enterprises and their equipment providers will face increased scrutiny given the projected quadrupling of their data-center GHG emissions by 2020
Significant failings in asset management (6% average server utilization, 56% facility utilization). Up to 30% of servers are dead [i.e. not being used at all, but consuming power nevertheless]
Data center facilities spend (CapEx and OpEx) is a large, quickly growing and very inefficient portion of the total IT budget in many technology intensive industries such as financial services and telecommunications. Some intensive data center users will face meaningfully reduced profitability if current trends continue
True costs are often 4-5x the cost of the server alone over a 5-10 year lifetime of a server
Incremental US demand for data center energy between now and 2010 is equivalent of 10 new power plants
EPA has advocated use of separate energy meters for large data centers
