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

Pumping systems without overhead tanks can significantly increase electricity bills of a group housing society
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

Inverter/UPS models and their energy efficiencies in India
Twenty-four hour power supply is a rarity in India. There are very few places in the country that can boast of having continuous supply of power. All this has resulted in growth of Inverters, UPS and DG sets industry in India. Although there are many branded models of inverters/ups available in the country, there are many people who still go for cheap/unbranded models that can significantly increase electricity bills. The efficiency of inverters/ups is not even considered

What is Energy Efficiency and how is it different from Energy Conservation?
While interacting with people we get these statements quite frequently: “Bijli Bachao! So you tell people to use less electricity and conserve it?” or “Your website has ideas on how to buy appliances, how does that relate to saving electricity?” The easiest way to save energy (or electricity) is to use less of it, but we have to be realistic in our approach. Our lifestyles are changing, and with increased pace of development, our need for appliances is increasing

Solar airconditioning: using sun’s energy when it most abundent and needed
Is solar energy sufficient to run air conditioners? If yes, how wonderful it would be to live in an air-conditioned place without bothering about the electricity bills! And the best thing: you use solar energy when it is most readily available and you need it the most. The question is however, can the AC run only on solar energy or does it need electricity as well. It depends on the technology and that has an impact on the cost of the AC. We at Bijli Bachao get this
