Believe it or not, the average desktop PC wastes nearly half the power delivered to it. Half! This wasted electricity unnecessarily increases the cost of powering a computer, and it also increases the emission of greenhouse gases.

Improving the energy efficiency of computers is a cost-effective way to reduce electricity consumption and the emission of greenhouse gases that contribute to climate change.

The Climate Savers Computing Initiative brings together industry, consumers and conservation organizations to significantly increase the energy efficiency of computers and servers.

Did You Know?
U.S. college students could save more than 2.3 billion kilowatt hours per year of electricity by enabling power saving features on their desktop PCs. That equals an annual savings of more than $200 million in energy costs and a 1.8 million-ton reduction of CO2 emissions from the operation of computers –equivalent to taking more than 350,000 cars off the road.2
