Tips: Saving on Electricity

I just received our electric bill this week. Guess what, our bill for the past month was at 6.7k. The previous electric bill was at 8.5k. That's a whopping 1.8k reduction and that's huge. Apparently our consumption reduced from 694kwh to 572kwh. That's a difference of 122kwh. So I tried recalling the things we have done to be able to achieve these savings.

The following are so far what I have recalled:

1. I had our two window-type aircon units cleaned.
2. I used electric with speed setting low and placing the fan nearer to me.
3. I used my 3G usb modem more often than our dsl + wifi.
4. I shutdown my laptop instead of sleep mode or hybernating.
5. I changed my usage of laptop and TV, ie not having them switched on at the same time.

I wonder if this trend will continue in the next bill as the next months will be summer and the aircons will consume a lot of electricity.
