The audits revealed a total of 2.1 terawatt-hours ( TWh ) of savings over the 20-year lifespan of the 2,000 motors . To put this into perspective , these savings are equivalent to powering 1.25 million houses – the size of a large city – for an entire year .
These audits were conducted across various countries , highlighting the global applicability of energy efficiency measures . However , to illustrate the potential impact , let ’ s consider a scenario where all motors were operating in the United Arab Emirates ( UAE ). Based on November 2023 data , a 2.1 TWh energy saving would avoid 1.5 million tons of CO2 emissions and have an ROI of six months . Alternatively , if these motors were in Germany , the savings would amount to 940,000 tons of CO2 and an ROI of just three months . These substantial savings would be enough to offset the emissions of a coal plant for three months in the UAE and two months in Germany .
By extrapolating these results to encompass the 300 million industrial motors operating worldwide , the potential impact of upgrading inefficient motors on a global scale becomes staggering .
ABB and CERN ’ s collaborative study One notable example was observed at CERN , the European Laboratory for Particle Physics . A study conducted by ABB and CERN in 2022 and 2023 , which included energy efficiency audits , helped identify potential savings of 17.4 %
