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
Ceiling Fan blade angle can impact electricity consumption
You have a few ceiling fans in your home or office, and you yourself clean them or ask your maid to clean them up regularly. You feel good when you look at nice and clean fans, but have you ever wondered if in the process you have mistakenly disturbed the fan blade angle? Recently during one of our visits at a home we found that the angles of ceiling fan blades were completely disturbed (as shown in the image below) and on asking the reason for the same, we found that
All about Electric Cars – technology for the future, pros and cons, and our take on it
Green living and green concepts are the new buzzwords in our age, and use of electric cars is gaining popularity in the green town. For most people, use of electric cars is an alien or a new concept, but it is not that these cars never existed, or were never tried. A good look at the history of cars will tell you that people started using electric cars way back in mid-19th century (some time in 1830s). These cars were popular even before the gasoline (or
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
Things that impact electricity consumption in air conditioners
It’s peak summer, and one thing that worries most people is: electricity consumption by air conditioners. No wonder, while buying air conditioner, people look for the most energy efficient ones, as air conditioners can bloat the electricity bills quite easily. Although buying an efficient AC does help, there are more things that impact electricity consumption of an air conditioner while one uses it. While going through an interesting research paper on IIT Madras
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
Comparing Ceiling Fans, Pedestal Fans, Table Fans and Coolers – which one is more efficient?
Recently we got a question on our website: “Ceiling Fans, Pedestal Fans, Table Fans or Coolers, which one is most cost effective?” and we started thinking that we have covered a whole lot about ceiling fans on our website but there are lot of other type of fans that people buy and certainly they wonder which one to buy as the difference between all of them is not clear. Also one would like to understand which one is more effective in terms of cost, efficiency and
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
What are Energy Performance Certificates or EPC
Labels on products that provide information on their energy consumption is an extremely popular method to help consumers take decisions. In India, the five star labelling scheme is used primarily for the electrical appliances to provide information on electricity use (link). Interestingly, in most of the western countries, the concept of labelling is also applied on automobiles and even houses.
