One habit poster, every Monday

• Shade: use trees, curtains and blinds to block direct heat
• Fan: ceiling and stand fans use far less energy than AC
• AC +1°C: raising your AC by one degree saves about 6% on your bill

Sources: the 6% per degree figure is from India’s Bureau of Energy Efficiency. The fan comparison is based on typical running power: a ceiling fan draws tens of watts, a room air conditioner around a thousand or more.

• Lights: turn off every light when you leave the room
• Devices: unplug chargers and devices not in use
• Standby: switch off at the wall

Dates may move.
