The Core line was introduced on the market two years ago and its low power consumption has always been one of its strengths, a little something that Intel apparently never forgot to stress out.

“So what did we find? When we added up all the Watt-hours that were saved in the past 2 years as a result of Intel’s “right hand turn”, the calculations point to approximately 20 Terawatts hours less energy used, relative to what our prior generation of processors would have consumed in the same time window,” said Lorie Wigle, General Manager, Eco-Technology Program Office Intel Corporation President Climate Savers Computing Initiative.

So: 20 Terawatts less energy had been used thanks to the new line, a figure Intel divided by an average energy cost of $0.10 per kilowatt hour and thus got to the final $2 billion energy savings.

“This is no small figure – it’s a significant amount of energy savings, and an example of what technology innovation by the ICT industry can do to improve energy efficiency on a large scale,” Wigle added.
