Yesterday, I bought a road TerraPass.
This program offsets the carbon dioxide emissions of vehicles, airplanes and home energy sources by funding alternative energy projects, like wind energy.
The TerraPass website calculates the emissions, then figures out the contribution needed to offset that amount of CO2 pollution. For my truck, it works out to about 12,000 pounds of CO2 a year, a pound per mile.
I found out about the TerraPass program at work: their hosting company is a corporate member.
A study published earlier this year estimated that servers, including cooling and auxiliary infrastructure, consume 1.2% of the total electricity in the US – about the same as color televisions.
