Energy efficiency

Using energy more efficiently brings many benefits: it makes the energy go further, curbs carbon dioxide emissions and saves money.





Today the most common primary sources of energy are fossil fuels, many millions of tons of which are burned each year to generate power. Through inefficiencies, from the gathering of these energy sources to their eventual consumption, a staggering 80 percent of their potential to generate power is lost.

With global energy consumption predicted to climb substantially by 2035, such high levels of inefficiency will needlessly add to the already growing carbon emissions. Estimates suggest energy efficiency improvements could deliver half the cuts in emissions needed to slow global warming over the next 25 years.

ABB has been in the energy business for 120 years and has pioneered many innovations that define the industrial and utility landscape today, such as high voltage direct current, variable speed drives, and industrial robots. Our technologies are used along the entire energy value chain from the extraction of resources and their transformation into electricity, liquefied natural gas or refined petroleum products, to their efficient use in industry, transportation and buildings. ABB can help industrial and utility customers improve energy efficiency by providing specialists to audit energy use and identify areas for improvement, and by providing equipment, systems and solutions to reduce energy consumption and improve productivity.

In 2011, ABB sponsored one of the most comprehensive overviews of energy efficiency in industry and utilities available, Trends in Global Energy Efficiency. This publication is a contribution to raising awareness about the importance of using energy more efficiently and the opportunities that exist for industry and power utilities.

The first part of this report measures and analyzes the attitudes and ambitions of business around the world regarding energy efficiency. The second part provides a global overview of energy efficiency in industry and utilities, as well as in-depth reviews of the countries which collectively account for 75% of the world’s energy consumption.

  • Reducing energy consumption in Poland

    2012-05-14: Poland’s two largest electric utilities have both selected ABB amorphous core distribution transformers to reduce energy losses in their power distribution networks. The transformers cut no-load energy losses by up to 70 percent compared to international reference standards – an energy efficiency level that is unequaled by any other type of distribution transformer.

  • Turning Lisbon’s waste into energy

    2012-04-10: An ABB variable speed drive solution has reduced the power consumption of the Valorsul waste-to-energy plant in Portugal by 9 megawatt-hours a day, equivalent to a saving of $320,000 a year at current energy prices. Valorsul processes the waste of Lisbon and much of western Portugal into valuable electrical energy, producing enough electricity to power a city of 150,000 inhabitants.

  • ABB drives and motors cut 4,000 MWh a year for Manchester Airport

    2012-04-02: A project to upgrade the Air Handling Units (AHUs) at Manchester Airport with ABB low voltage drives and ABB high-efficiency IE2 motors is saving annually 4,000 MWh, as well as cutting CO2 emissions by over 2,000 metric tons a year.

  • Earth Hour 2012: active houses contribute to the development of smart grids

    2012-03-26: Millions of people around the world will switch off the lights for Earth Hour, a global initiative to demonstrate concern about climate change. ABB supports efforts to conserve energy, increase the integration of renewable energy and protect the environment – and increasingly works with partners to develop practical solutions.

  • 3,000 fans with CO2 sensors keep students cool

    2012-03-26: Using 1,000 sensors, over 3,000 fans and a ventilation system that is activated only when the amount of carbon dioxide in the room reaches a certain level, a Swedish university library has reduced electricity and heating costs by up to $220,000 a year.
