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
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
Best Gas Stoves and How to Save LPG used by cook stoves

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
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
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
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
Innovative lighting solution that works without electricity

Being an engineer my mind always thinks of using science to solve practical problems. And when I used to think about lighting, I always used to think: why don’t we effectively use sunlight to light a room during the daytime? Why do we have to use electricity? When we were kids, while playing we used to use mirrors to reflect light on to each other. When I grew up I used to think of using such simple concepts to harness sun light to light a room during the day. And
