Offset your Facebook habit with Greenbook
Facebook servers and your computer use energy, which puts CO2 in the air. Boo! Step in Greenbook, the latest must-have facebook accessory which aims to offset the carbon generated by all those millions of tapping fingers.
Greenbook works by buying renewable energy credits; certificates that prove that electricity produced by traditional (potentially harmful) means were replaced by equal amounts of energy produced by green methods. Unlike many such schemes, Greenbook does not rely on tree-planting for its carbon offsets. Instead, it invests in 'green power', namely renewable sources such as solar and wind power. To pay for this, it has to get companies to sponsor it: the more users sign up, the more sponsorship they get. So why not sign up today? I promise it's far more rewarding than being a zombie.
