The quest for higher performance can cost companies dearly. IBM, citing numbers compiled from third parties, said that about 25 percent of a company's data-center budget goes to providing electricity to run and cool computers. Overall, about 10 percent of the electricity consumed in North America goes to support information technology systems, according to a U.S. Energy Department study cited by Big Blue.
Without consumption curbs, the amount of energy used to power and then cool computing equipment will increase exponentially, IBM executives said.
