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.

After so many years, when I think of it, a lot of it can be applied to saving

Air Conditioners with Heat Pump can save electricity for heating in winters
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. It not only adds to the number of appliances in a house, but also significantly increases electricity bills in summers as well as winters.
