- - Switch to 5-star BEE-rated appliances - they use 30-50% less electricity
- - Use LED bulbs (7W LED = 60W incandescent in brightness)
- - Set AC to 24-26 degrees C - each degree below 24 increases consumption ~6%
- - Avoid peak hours (6-10 PM) if your DISCOM has time-of-use tariffs
- - A 1kW solar rooftop panel generates ~100-120 units/month in India
