When we moved into our new home, we made sure all the lights we used most often had CFLs. Following the 80-20 rule on lights seemed the most practical option given that I would have to spend only an extra Rs 1500 on those few CFLs instead of > Rs 5000 if we had CFLs everywhere.
Recently, I identified the “Tier II” lights that could use CFLs. So I bought a Rs 200 CFL to replace the existing Rs 10 bulb in a light that was used for about an hour everyday. The problem that I didn’t expect to face, was that I had no idea what to do with the perfectly good bulb that was replaced.
There weren’t any empty sockets to plug it into. I didn’t want to keep it as a spare, because if another bulb blew, that would be a good opportunity to use yet another CFL. It could have been donated to the domestic help to use at their house but that wouldn’t save any electricity at the macro level. The last option was to break the bulb and dispose it.
This bulb dilemma is a good reflection of most energy efficiency initiatives and or initiatives to reduce CO2. When there is a new initiative or project and if there is enough money to invest, it’s easy to “buy new CFLs” and save money through efficiencies. The problem is with existing assets. How much money can one spend to upgrade these and what does one do with the residual value of replaced assets? It’s difficult to find projects with no upfront or ongoing costs.
Now the question is, what do I do with the bulb lying on my table?
