The huge data centers that power the Internet could end up costing companies like Google millions more under a "cap and trade" carbon emissions reduction program.
That's because most of the nation's electricity is still produced by coal-fired power plants, and data centers are one of the fastest-growing consumers of electricity.
Google spends approximately $38 million a year on electricity for its data centers nationwide, and a carbon tax could increase that by as much as 50 percent or more.
Even though that money is chump change for Google, the company is aggressively investing in a project dubbed "RE < C," an effort to create renewable energy sources that are cheaper than coal.
In England, where nearly all electricity comes from coal, a carbon reduction tax has already been implemented and no new data centers have been built.
Suggesting that some companies may simply move their power-hungry operations to other countries.
