According to the International Energy Agency (IEA), electric motors account for 45% of the global energy consumption. They are everywhere: on hair dryers, washing machines, fans, on each elevator we find one, converters and much more. Motors are the main global energy consumers. Still according to the IEA, lighting systems come in second, with 19% of the world consumption. This means that every second electrical plants produce energy with the sole purpose or powering motors.
In 60 seconds, motors across the world use energy enough to meet the yearly demand (that’s right, yearly) of 12.7 thousand households in China. The surprising analysis is the first on a global scale regarding electric motors’ energy consumption. The novelty of the same research is that it also shows how much energy can be saved. According to the IEA data, it is possible to save from 20% to 30% of the total motors consumption, which would mean a 9% to 14% reduction of global energy consumption. Despite seeming impossible, IEA assures there is great potential, even though various obstacles hamper the access to such investments.
Through a worldwide research with production executives, it was revealed that 60% of business owners have not invested capital in energy efficiency, plants or equipment at all over the past three years, claiming a lack of funding for improvements in energy efficiency, a lack of money and information regarding available options and the main obstacles to perform such improvements. Which is surprising, after all motors account for two thirds of the energy used in the industry, and the annual energy cost of a motor can be up to seven times its price of sale. The IEA report reveals the key role played by electric motors in the economy. It is time to place them in the center of our strategies, so that we can meet our imposed energy and environmental challenges.
