Green Living at Home: The Economics
Star Labels and Efficient Appliances
How India's energy star labels help buyers compare appliances, why five-star models often save money, and how standards push manufacturers.
When buying a fridge, air conditioner or fan, you’ll often see a star label.
The star labelling programme
India’s Bureau of Energy Efficiency (BEE) launched the Standards and Labelling Programme in 2006. Appliances get 1 to 5 stars, with more stars meaning higher efficiency.
Labels are mandatory for many products, including air conditioners, refrigerators, ceiling fans, water heaters and LED lamps.
What the label shows
- Star rating.
- Annual energy consumption in units (kilowatt-hours).
- Year of rating, since standards are tightened over time.
Why it matters
- Information: buyers can compare running costs easily, solving an information problem.
- Savings: a five-star AC can use significantly less electricity than a one- or two-star model.
- Pushing manufacturers: as BEE raises standards, yesterday’s five-star becomes today’s three-star, encouraging innovation.
Inverter ACs
Inverter air conditioners adjust compressor speed rather than switching on and off, saving energy. BEE’s ratings account for seasonal efficiency.
Doing the maths
An AC used 8 hours a day for 6 months might use hundreds of units less per year with a higher star rating. At 7 rupees a unit, savings can reach a few thousand rupees a year.
Tip
Compare annual energy use on the label, not just stars, and consider how much you’ll use the appliance.
A family chooses between a three-star AC and a five-star AC costing 7,000 rupees more. The label shows the five-star uses about 300 fewer units a year. At 8 rupees a unit, it saves 2,400 rupees a year, paying back in about three years.
BEE tightens standards over time, so check the label's year.
- BEE's star labels, from 2006, rate appliance efficiency from 1 to 5 stars.
- Labels show annual energy consumption for easy comparison.
- Rising standards push manufacturers to improve.
- Compare annual energy use and your expected usage.
