We used to watch movies on DVD, which means plugging in a DVD player and a separate TV set. Now we just use the laptop.

The light hovering above our dinner table is composed of two bulbs: one circular fluorescent lamp and one CFL. We switch it to the latter when we retire for the night, since we don't really need that much brightness anyway.

I also try to avoid using the electric water heater (2000W), but as it is, LPG runs out more often than electricity.

And whenever possible, instead of charging my mobile phone at home, I do it in the office.
