Please do not waste money on “vampire power”. I can imagine many eyes rolling. What is this curious thing called vampire power? Never heard the term before? If we are not using it, where is the question of wasting money on it? Well, vampire power is a term to denote the power consumed when we leave any electrical appliance in a stand-by mode. The power is consumed by power supplies (the black cubes – sometimes called “vampires” – converting AC into DC), the circuits and sensors needed to receive a remote signal, soft keypads and displays including LED status lights. Now that sounds familiar!
Usually, we switch off our television only by remote control. That means we are paying Rs 55 extra annually for that and set-up box combined. Instead, if we pledge not to be a couch potato and get up to switch off the TV and set-up box from the main switch, that alone can save Rs 55 per year. That might not come to much, but if we add to it the amount saved by switching off the main switches of all the electrical appliances in our homes, that alone can save energy worth Rs 500-1000. That means out of 2 crore consumers, if only 50 lakh consumers do this, the amount would cumulate to around 54 crore units per year.
Now that is surely a huge sum, and a sum calculated by the electricity department in our country. Given below is a table of energy wasted due to our negligence in a year:
According to a study, daily people plug in their mobiles to be charged during the night. While the mobile usually takes 2-3 hours to charge, the rest of the electricity is just consumed by the charger. Because the mobile is plugged onto the charging point for around 6 hours, it wastefully consumes around 0.14 unit electricity daily. If 8 crore mobile owners do this, then 19.2 lakh units are wasted. That means around 1920 MW of energy is wasted daily. The government spends around Rs 10, 000 crore to manufacture so much electrical power!
The Energy Saving Trust, UK, believes the British could save 1.7 billion pounds a year by switching off appliances completely instead of leaving them on standby mode. Indians could certainly learn from this study and take our own measures to reduce wasteful consumption of electricity.
We keep cribbing about hikes in the price of electricity per unit every time the government announces a raise in it. While we do have the right to ask for reasonable rates for power consumption, we, as responsible citizens, also have the duty to cut down our own useless electricity consumption. It is not very difficult to do if we commit ourselves to it.
