On which of the following, can you find the Bureau of Energy Efficiency Star Label? 1. Ceiling fans 2. Electric geysers 3. Tubular fluorescent lamps Select the correct answer using the codes given below:

All three products carry the BEE star label, so the answer is D. The star label is the Bureau of Energy Efficiency's rating system, created under the Energy Conservation Act, 2001. The 1 to 5 stars tell the buyer how energy efficient an appliance is, and the programme was launched in 2006.

• Tubular fluorescent lamps (3): covered from the early years of the programme, so statement 3 is correct.
• Electric geysers (2): storage-type water heaters are covered, so statement 2 is correct.
• Ceiling fans (1): covered under the BEE star labelling scheme, so statement 1 is correct.

Option A drops tubular lamps, B drops ceiling fans and geysers, and C drops ceiling fans. Each of these omits a product that does carry the label, so D is the only option that includes all three. The list has expanded since 2016, so check the current BEE list rather than relying on memory.

Core concept: BEE star labelling and its link to energy efficiency, demand-side management and climate policy, a useful GS-III point for Mains.

Trap: Many aspirants assume the label is only for big appliances such as refrigerators and air conditioners, and reject ceiling fans or geysers on that basis.
