What will happen when the gas runs out, when the deepest oil well of the Arabian peninsula finally runs dry, when the giant drills of the offshore platforms reach nothing but dry rock? Will we face a future of blackouts and electricity rationing, or will we find a way to avert the doomiest scenarios and continue living lives in which energy consumption is crucial to everything we do. Think of the electricity you use in a day. You are woken by the clock radio buzzing into life, and you turn the bathroom light on as you climb into your power shower. After dressing you head downstairs, where you turn on another radio, put some bread into the toaster and turn on the kettle, getting the milk from your fridge to put in your tea. After breakfast you head to work, where the lights are burning - and on go the computer and desktop fan.

Hydrogen is a better source of energy than you think, according to Fujitsu. The Japanese electronics giant inaugurated a 200-kilowatt hydrogen fuel cell from UTC on Friday that will provide electricity as well as heat to the buildings on its campus here. The fuel cell--which sits in the parking lot and looks like a pair of giant green dumpsters--provides two types of energy to the facility. First, a unit heats methane with steam to create hydrogen. The hydrogen is passed through a proton exchange membrane (PEM). The electricity produced by the reaction with the PEM runs lights, computers and other equipment

Computing giant IBM and French electric utility EDF will together research ways to boost the efficiency of power plants and modernize electricity infrastructure, IBM announced today. The collaboration puts them in the thick of what's known as the smart grid industry,

Now Andrew Hopper , head of the Cambridge University Computing Lab, is working on a solution that could help reduce the demand data centers place on the grid.

A fraction of a small fraction will be small, but as an education project, it serves a similar role as CFL's for example. 100 Watt is heat produced at rest. Producing 100 W of electricity is quite a different thing and is not 'at rest' at all, although it is not a huge physical effort either.
