Converting V-belt drives to synchronous belt drives can reduce energy usage.
To estimate the number of kilowatt-hours saved by using synchronous belt drives rather than V-belt drives, the following calculation can be used:
KWH= (motor hp x hours/year x .746 x.05)/motor efficiency
where constant .746 is the conversion factor from hp to KW and .05 is the estimated 5% energy savings gained by converting to synchronous belt drives.
