IBM has revealed the possible cost savings that can be achieved from implementing an energy-saving program. Big Blue announced that it achieved strong sustainability results in energy conservation, data centre energy efficiency and environmental responsibility to the tune of saving $43 million (£27m) in electricity expenses last year. Energy Efficiency IBM said that not only did it save more than $43 million in electricity expenses, but it also conserved 378,000 megawatt-hours of electricity – enough to power almost 34,000 average US homes for a year. IBM’s energy conservation projects delivered savings equal to 7.4 percent of the company’s total energy use, significantly exceeding the annual goal of 3.5 percent, IBM officials said.
