It is criminal to use Electric Hot Water Geyser
When you use the electric geyser to heat water for your bath, Do you realise what you are contributing to the climate change through carbon emission:
Well, the 1 Kw water heater is the most common gadget in any house. And we proudly tell all the guests that we have geysers in all the bathrooms.
Did we realise what we are doing?
A 1 Kw heater consumes 1 Kwh or one unit of electricity in one hour.
This unit is available at our plug point after having consumed the about 30% transmission and distribution losses from the generating station.
This means, some one is generating 1.43 units somewhere else. ( for evey .7 Kw at the user end, another .3 Kw has to be generated, hence for 1 unit at user end, 1.43 units generated)It takes about 700 gms of coal to generate one unit of electricity.
So, for 1.43 units, some one is burning about 1000 gms of coal or one Kg. If we consider the ovrall efficiencies of the geysers, you could as well multiply the figures by almost 2.5 times.
This one Kg coal generates it's own part of the carbon di oxide.
Now look at the other way. 1 Kg coal contains about 4000 KCals of heat.
One more way of looking at this is to know that we burn coal to heat water, then make steam out of it, run a turbine through this steam, generate electricity, transmit it all the way, distribute it through the network, bring it to our plug point and then again use it to heat water.
Think seriously. Is it necessary for us to use electricity for heating water. Just try taking cold water bath. Its so soothing. And in turn, help environment, by contributing your own little bit.
I am doing it for more than twenty years. You can try it too.
After all, coal is not going to last for ever. A day will come when we will not have it at all.
