Energy Saving Tips

Use LED Bulbs

Replace incandescent bulbs with LEDs to save up to 80% on lighting costs.

Optimize AC Usage

Set AC to 24°C – each degree lower increases consumption by 6%.

Unplug Devices

Standby power can account for 10% of your electricity bill.

Use Natural Light

Open curtains during the day to reduce the need for artificial lighting.
