Time Switches: easy automatic way to switch on and off appliances and save electricity
We all know that switching off appliances from the mains is one of the best way to save electricity. Still, at times we encounter situations where doing the same is either a hassle or is difficult. Running an AC all night will consume a lot of electricity and will also make the room quite cool, but getting up in the middle of the night to switch off is a hassle. A switched on TV/DTH-DVR system will consume quite a lot of electricity,

Learning from a Thermos – Designing a well insulated space
When I was a child I used to have a lot of curiosity while using a Thermos (or vacuum flask). It was always like magic that it used to keep hot things hot and cold things cold all the time.

Later in high school we learnt the basics of heat transfer, and that was when the theory behind the thermos became clear to me. After so many years, when I think of it, a lot of it can be applied to saving

We were on regular fans about a year back, when we replaced them with BEE 5 star rated ceiling fans. And just 3 months

Several places in Northern India experience extreme winters and summers every year. To deal with such extreme weather, most people buy both air conditioners as well as room heaters.

Air conditioners because they have a thermostat (which controls temperature) do not consume a lot of electricity as compared to room heaters, which

A few months back we got a call from the management committee of a luxury residential complex in Mumbai to help them on their very high electricity bills. Surprisingly their common electricity bills were so high that their monthly maintenance bills were as high as what a family would pay as rent in any other society in the city. On a walk through audit we found that although the lighting used in the complex was most efficient, what was causing high electricity bills
