GoKawiilUnderused motor devices could unlock gigawatts of spare U.S. grid capacity
Roughly 50 million electric motors powering fans, pumps and compressors across U.S. factories and buildings consume nearly a third of the country's electricity, often far more than necessary. Variable frequency drives (VFDs) can cut that waste, but a 2021 Lawrence Berkeley National Laboratory report found only 16 percent of industrial motor systems and 4 percent of commercial ones use them, largely due to installation hassle and lack of mandates.
GoKawiil's interpretation of the reporting above, not reported fact.
Energy experts and device makers argue that wider VFD adoption could free up grid headroom just as data centers, EVs and electrified heat pumps strain capacity and push industrial power prices higher. Because VFDs have reportedly become cheaper and more advanced, the case for incentives or efficiency standards may be strengthening, though actual uptake will depend on whether utilities, regulators and large tech companies act on these calls.
- 50 million U.S. motors use power equal to about a third of national electricity demand.
- Only 16% of industrial and 4% of commercial motor systems currently use efficiency-boosting VFDs.
- Advocates say incentives or standards could unlock grid capacity for data centers, EVs and electrified heating.
