Avoid repeated rewinding of motors. Observations show that rewound motors practically have an efficiency loss of up to 5%. This is mainly due to increase in no load losses. Hence use such rewound motors on low duty cycle applications only.
Replacement of inefficient aluminum or fabricated steel fans by moulded FRP fans with aerofoil designs results in electricity savings in the range of 15-40%.
- Make sure the voltage of the motor is as close to the design limits, found on the nameplate, as possible. Voltage at the motor that is not within the design limits leads to a decrease in power factor. Low power factors may be monetarily penalized by your power company.
- Turn off the monitor if you aren’t going to use your PC for more than 20 minutes.
- Turn off both the CPU and monitor if you’re not going to use your PC for more than 2 hours to save money on your energy bill.
- Replace light bulb with Led lights.
- Unplug electronics when not in use.
- Load Up dishwasher until full.
- Keep cooling with ceilings fan.
- Power down your computer.
- wash clothes in cold water.
An Copy machine left overnight waste enough energy to make over 1500 copies.
Consider using desk lamps (“task lighting”) and reducing overhead lighting in the room.This will save expenditure of using high wattage in lighting.
- Consider a laptop next time you’re looking to buy a computer – they use less energy than desktop computers.
- Set your computer to sleep or hibernate mode instead of using a screen saver so it uses less electricity during periods of inactivity.
- Unplug battery chargers when the batteries are fully charged or the chargers are not in use. Many chargers draw power continuously, even when the device is not plugged into the charger.
An idling compressor uses around 40% of its full load. Where appropriate, turn compressors off when they’re not being used (for example during tea breaks, and certainly overnight), to save energy.
