How to Save Electricity

One day i was happily coming back from work, went to my room and turn on the PC. I was about to do the normal stuff i do online when suddenly i heard a faint voice calling me from downstairs. The voice was my mum calling my name over and over again. So fine, I went down to see what did she want. When i was there, guess what? The electric bill was in her hand and she started to preach about my usage.
I didn't recall using so much of electricity since most of the time i will be at work or out with my friends for "yam cha", shopping, movies, gym and many more. Other times i will be asleep. Its true sometimes when i was asleep, i will leave the PC on for downloading stuffs but then again, it was never that much. Basically i only use my house electric to online, air conditioner and charge my mobile.Then i was like "ok, thats it, i'm gonna find out what was actually causing so much". After the lecture, i went to my PC and quickly find the tips on how to conserve electricity.
