IBM is launching
Big Green. Part of the initiative is to consolidate
operations in the world’s largest data centers. They will
replace nearly 4,000 servers with 30 refrigerator-sized
Z mainframes, running Linux, using virtualization technology.
This will reduce energy usage by about 80%, saving about $250
million per year.
What’s more, the consolidation will leave plenty of room for

its campus to a methane-producing landfill, generating energy
using methane that otherwise would be vented into the atmosphere.
The project is expected to provide 85% of their energy needs.
Because it is using carbon that would be going into the
atmosphere anyway, it is considered carbon-neutral.
The U.S. Federal Energy Regulatory Commission has changed its
regulations for installation of href="http://www.spectrum.ieee.org/aug07/5449">tidal energy
systems. The regulatory structure had been so
cumbersome that it effectively prevented the exploitation of this
environmentally-friendly resource. It is estimated that this
could eventually satisfy 6.5 percent of total US energy demand.
Progress is being made in the commercialization of
batteries for automobiles. It is hoped that the
products will be on the road in quantity by 2009.
Lithium-ion batteries provide twice the energy density (energy per
kilogram) of current technology, leading to much greater efficiency.
