Homeworking - good for nature?

Commenting on the Oxford University report we mentioned here last week, Peter Warren in the Guardian's technology pages suggests that it's not as simple as homeworking good, officeworking bad when it comes to the environment. Warren writes: ""The more that people work from home, the more computers there will be," says Jon Godfrey of Lifecycle Services, which specialises in recycling old machines. Meanwhile, increasingly powerful computers demand increasingly hungry power supply units, says Godfrey. "Computers used to have 250W power supplies. Now modern computers have 500W power supplies. They also have items like servers and routers which are left permanently on."
