Personal cost control

That's the safest way to eat ... especially if you are watching out for every intakes like the calories, fats, etc. 

Today most of the working class people don't carry their lunch to their offices most of them go out for lunch and this is taking more from their pocket they imagine, and yes arijita is right here have home made food most of the time and one can control cost...

Fully agree with you. 

Yes i agree to this format where simply one person who is travelling with his car to work is just waste of fuel and if the same car has like 4 people in it, it will really help in less fuel consumption and will also help in causing less global warming, infact people should also do bike pooling where there are more number of two wheelers that are seen these days...

True car and bike pooling are very good methods to follow, and you will have a companion while commuting, rather than those lone frustrating rides in heavy traffic - serves two purposes.

I agree devi mam with your opinion.

However this small things are ignored by many of us but result in huge amount of energy wastage and big electricity bills.

But by taking several factors into account one can reduce electricity consumption such as - >

Computers use up to 70% less electricity when you put them in sleep mode. So don’t use screen savers.

You can also use the power saving kits which are available which can reduce the power consumption till 20-25%.

Make minimum use of bulbs or tube lights during daytime. And use natural light.

Switch off lights and fans when you are out of room or house. Reduce high wattage bulbs where less light is needed.
