Energy efficiency – a solution
Pressures to reduce energy consumption and lower
carbon dioxide emissions come from everywhere.
The simplest way to address this challenge is to seize theopportunities for energy reduction that come from using
energy more efficiently.

Using ABB’s variable speed drives and highefficiency motors to intelligently run applications
increases energy efficiency. This has enormous
positive financial, operational and environmental
implications.

Energy efficiency – motors and drives play a major roleGlobally, demand for electricity will grow faster than for
any other form of final energy. Thus, emissions will keep
rising, unless we start doing something different.

The additional purchase price of ABB high efficiency motor and variable
speed drive is just a few percent compared to the energy spent to run theequipment over its entire lifetime.
Energy savings with variable speed drives and high efficiency motors
typically pay for themselves in. In some cases return on
investment (ROI) of VSDs can come within months.

We have great saving potential of thelife cycle energy consumption!
—Regulations paves the way for sustainable future
Efficiency requirements for low voltage motors.
Minimum Energy Performance Standards (MEPS) sets mandatory
minimum efficiency levels for electric motors introduced into local andregional markets.
Only a small fraction of all motors comply with high energy standards oftoday. ABB is the frontrunner in developing high efficiency motors andsetting the bar for even more energy efficient motor technologies.

According to affinity laws, pumps and fans running half speed consume
only 1/8 of power.
Variable speed drives regulate the speed of a motor (and pump or fan)and can reduce energy consumption by as much as 30% to 50% inmany applications and in extreme cases by as much as by 90%.
Every second motor is running a pump or fan.

Thanks to affinity laws, saving potential withspeed control is huge, globally.

—Save energy and optimize operations in a sustainable wayVariable speed drives and high efficiency motors are themost affordable and effective way to increase energy
efficiency in industry.

In 2016 ABB installedmotor system baseglobally saves:490 TWh
490 TWh is
20% more thanannual electricity

—Energy saved with ABB’s variable speed drives
Significant annual energy savings implemented – butmore needs to be done to decrease the ever growing
demand for electricity.
The installed base of ABB
drives saved about 515 TWhin 2017, equivalent to theconsumption per year of
more than 130 millionhouseholds in EU.

ABB drives reduced CO2
emissions in 2017 by about
413 million tons,
corresponding to the yearly
emission of more than
