Google in Megawatt


Impressive picture from Google datacenter in Iowa. Here is where your google searches (three billion per day), youtube requests and gmail are processed, as well as in twelve other, similar data centers around the world. Power consumption world wide: 260 MW. It is Google’s policy to apply electricity from renewable sources and for this gets a best note from Greenpeace.

Japan Asks For Power Usage Cuts


Welcome to the new reality of energy scarcity. If a highly advanced country like Japan asks its citizens to voluntarily cut energy use, one can be assured that something big is in the making. In western Japan energy consumers will be asked to reduce demand by at least 15% compared with peak levels in the summer of 2010 for the period from July 2 through Sept. 7. The power cuts are linked to the nuclear power stations that were taken off the grid after the desaster in Fukushima. There is no reason not to assume that this will be a recurring pattern in the years to come, until the moment arrives where electricity will be rationed.

London buses equiped with flywheels

[Source pic]
Pilot project involving 6 buses. Expected fuel savings up to 30%. If successfull, implementation on all 4,000 companies fleet buses could be considered. In essence, rather than wasting kinetic energy as heat in breaks, it is transformed in kinetic energy of a rotating flywheel (‘mechanical battery as it were’). This energy again is used to bring a bus up to speed from standstil and thus the bus engine saves fuel. Return on investment with current high fuel prices estimated to be five years.
