Did You Know ??

Hi everyone!

Do you know what contributes to your monthly electricity bill?

For those in Semenanjung Malaysia, TNB tariff is approximately 30 sen to 45 sen per kilowatt-hour (kWh), depending on your usage. The more you use, the more expensive the rates!

Below is a short table of common electrical appliances, and a rough estimate on how much they cost to run for every hour.

(The cost may seem low, but remember, even using 3 sen/hour means that you will be paying about RM 20 a month if you leave it on for 24 hours a day!)
