Happy with the Compact Fluorescent Lamps (CFL) at your home, thinking your power is now saved due to CFL? Are they Environment Friendly? Think again? CFL is undoubtedly cost effective and energy efficient. Delhi Government which once went out of its way to promote CFL is now beginning to harbour second thoughts over how environment friendly they really are.
There is no proper facility for the disposal of fused CFL bulbs and in the long run it may damage the environment. Government is concerned as CFL bulbs contain mercury and disposing them might create environment hazards.
Chief Minister Sheila Dikshit is also worried and has already asked power department officials to research the possibility of switching to lamps based on Light-Emitting Diode (LED) technology which could be a substitute to CFLs. LED promise to last longer and use less energy than even compact fluorescents (CFLs)
CFL is highly energy efficient. It is an advanced lighting device which contains mercury, a hazardous material, and the city does not have any system for proper disposal of broken or fused CFLs.
The Chief Minister for starter is looking in trying out LED bulbs in government buildings to test their efficaciousness and energy efficiency.
Tata Energy Research Institute and the Delhi Government has signed an agreement last week to fit LED lights in 100 existing buildings with over 10,000 sq ft area to make them energy efficient.
As per senior environmental department official, LED lights are very expensive but they do not contain hazardous chemicals and could be recycled. LED lights are more energy efficient than CFls.
Not only the Delhi Government but the Centre for Science and Environment (CSE) had also raised concern over absence of a proper system for the disposal of mercury used in CFls.
To this, CSE had said the quantity of mercury should be reduced in CFLs like in other advanced countries. In India, CFLs sold contains 3-13 mg of mercury content whereas in US and Europe CFLs with 1mg is also available.
LEDs have been around for years, ab initio showing up in the displays of the first electronic calculators and then gaining fame as power or status indicator lights in products ranging from computers to alarm systems. In recent years, they've also started to pop up in many other products, including stoplights, flashlights, solar-powered walkway lamps and strings of Christmas tree lights.
