Tip # 1:
The back of your refrigirator releases great amounts of wasted heat.
You can use that heat to dry your wet clothes. Just hang it within
the free space between the back of the ref and the wall.

Tip # 2:
During rainy season, your roof acts like a giant water collector.
Design one end of your roof drainage to divert the collected rain
water to a receptacle. You can use that collected rain water to
flush your toilet. You can save electricity from your water pump.

Tip # 3:
If you have convenient space outside your house, you can cook
using combustible materials you would normally throw away like
old newspapers, used cartons, and other stuffs. There are cheap
portable ovens you can buy specially for that purpose.
