According to ABB, around 310 million megawatt-hours (MWh) of electric power was saved by the installed base of its drives in 2011, an increase of 19% on the previous year.
The savings correspond to 260 million tons of CO2 emissions – had this power been generated by fossil fuels – or electricity costs savings of approximately £27 billion for customers. These savings are said to be equivalent to the electricity generated by more than 30 nuclear power station blocks, or to over three and a half years power consumption of the UK’s 26 million households.
“The future potential for energy and cost savings is enormous since only about 10% of industrial motors are combined currently with electric drives,” said Ulrich Spiesshofer, member of the Group Executive committee and head of ABB’s Discrete Automation and Motion division. “Using energy more efficiently will remain, for a significant time, the biggest opportunity available to cut energy consumption as well as costs and emissions.”
