Discover efficiency and improvements based on our research.
Variable speed pumps are greener. Their efficiency means both more sustainable products and operations that save money on energy bills.
More Efficient Motors
According to the U.S. Environmental Protection Agency (EPA), more than half of the electricity used in manufacturing powers various motors. And if we focus on the industrial energy-related carbon dioxide emissions, they reach over 1,300 million tonnes per year in the U.S. alone. Industry in the country is responsible for almost a quarter of its greenhouse gas emissions.
The International Energy Agency (IEA) notes that electric motors and systems account for over 40% of electricity consumption globally. They also state that, despite the small COVID-related decline in 2020 emissions, “global energy-related CO2 emissions remained at 31.5 Gt, which contributed to CO2 reaching its highest-ever average annual concentration in the atmosphere of 412.5 parts per million.” 40% of 31.5 Gt is 12.6 Gt. This is a significant contribution to climate change.
Industry and manufacturing leaders have the opportunity to embrace sustainability and reduce energy use by employing more efficient motor systems. Experts estimate that if high-efficiency motor systems were adopted globally, it would cut electricity consumption by up to 10%.
The e in ePropelled stands for efficiency. This is because our goal is to use innovative technology and expertise to deliver significant improvements in motor efficiency. As a result, what we have done for eMobility and air transport can be applied to building motors suited for a variety of applications.
The Natural Resources Defense Council (NRDC) estimates that residential pool pumps alone use 9-14 billion kWh per year. In general, companies that reduce the environmental footprint of their commercial pumps will have a competitive advantage in the market. Not only because of consumer preference. There are options that can make pumps environmentally friendly, save money, and deliver the required performance, despite some companies, manufacturers, and operators considering sustainable pumps to be too expensive or not powerful enough.
In water handling, pumping can consume up to 85% of the energy used. But according to ABB, improved systems with variable speed drives and high-efficiency motors could result in energy savings of 25 to 30%. And pumps are used in many more systems and applications, so improving efficiency by even a small percentage would dramatically cut the related CO2 emissions. It’s not surprising that, within the pool and spa markets, the U.S. Department of Energy has mandated the use of variable speed motors in pumps rated at 5 hp and below as of July 2021.
In the end, efficiency is the way forward. Energy-efficient electric pump motors have much less impact on the environment, and they are powerful enough for applications ranging from commercial, residential, and cleaning, through misting, pest control, and dust suppression, to pool and spa. What’s more, variable speed motors can simplify inventory since they can cover a broader range of applications.
Heating, cooling, and ventilation add up to over 25% of the electricity used in the U.S. commercial sector alone. In U.S. households, this number rises to over 50%. According to the IEA, there were 1.6 billion HVAC units in the world in 2018. They were predicting that this number would grow to 5.6 billion by 2030 due to improving income and living standards in many developing countries. CNBC quoted this increase as potentially reaching 14 billion by 2050.
Four years ago, air conditioners and electric fans already accounted for about 20% of the total electricity used in buildings around the world (10% of all global electricity consumption at the time), and AC use will likely be the second-largest source of global electricity demand growth (after the industry sector).
As it stands, the current AC technology hasn’t really changed that much in over 100 years. We need significant improvements to the technology and the motors and pumps used in it.
