Light Meter App on mobile phone: easy way to optimize room lighting and save electricity
One of the biggest challenges while setting up lights in a room is to understand how much lighting is good lighting. People end up putting multiple CFLs, Tube lights, down-lighters, which at times is more than required and also consume electricity more than what is needed. In a previous post on Task Based Lighting we had discussed about the amount of light required in
Microwave Ovens: Science behind it; comparison with gas stove; and some myths/realties
Microwave ovens are there in Indian market since quite some time, but it is only in the last few years that they have caught the fancy of Indian kitchen. We at Bijli Bachao get several requests asking for suggestions for buying microwave ovens and thus we picked it up as a topic to research about. The Bureau of Energy Efficiency in India currently does not have any star rating or standards for Energy Efficiency of Microwave Ovens and thus none of the microwave models
Use right detergents with washing machine for efficient use
While buying a washing machine, we always try to buy the best that we can. Many people also think of buying the most efficient washing machine. But it’s not just the washing machine that matters; even the detergent that we use with the washing machine that drives the efficiency of the washing machine. With improvements in technology for washing machines, even the formulations and chemicals for detergents are changing so that they match the requirements of new technologies.
Top 10 ideas for saving petrol/fuel in your car/vehicle
There was a time not long time ago when the prices of petrol/fuel were quite reasonable. The prices of all kinds of fuel: petrol, diesel, etc have skyrocketed in last few years. A recent ad on TV by a car company had a dialogue: “Kitna deti hai” (how much does it give), summed up the preference that most people in India have. No wonder fuel efficiency is one of the primary factors that influences buying decision of most Indians. But still the rising cost of fuel
Save LPG used by cook stoves: Make sure your gas burners burn blue for higher fuel efficiency
Although induction cooktops are gaining popularity, but traditional old gas stoves are still the most used cooking appliance in households. At Bijli Bachao, we profess saving energy, and although our name gives a feeling of saving electricity, but saving other sources of energy are as dear to us. LPG and PNG are the most common fuel used for cooking on gas stoves in India, and saving them is as important as saving electricity. Although there are several things that
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,
Choose the right taps and showers for bathroom/kitchen to save electricity
World over there are talks going on about saving resources. In addition to energy, water is an equally or even more important resource to save. At homes, people are mostly concerned about saving electricity, as the charges of electricity are more as compared to the amount they pay for water. But at Bijli Bachao we have repeatedly mentioned that saving water can also save electricity. If there is efficient use of hot water in a house it can save electricity required
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. It neither had fire in it to keep things hot nor ice to keep things cool. 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
Evaluation and comparison of Superfan, a BEE 5 star rated fan and regular fans
Since we started Bijli Bachao, which was almost two years back, we have been experimenting with various appliances and measuring their electricity consumption. At our own home we measured electricity consumption of some of the appliances, replaced them with efficient options and estimated the impact post replacement. One of these is the ceiling fan. We were on regular fans about a year back, when we replaced them with BEE 5 star rated ceiling fans. And just 3 months
