The Andhra Pradesh government has been adopting a special mechanism on energy
conservation on war footing, and it has been putting all efforts to achieve the
desired goals by implementing energy efficiency programmes like DSM-based
conservation on war footing, and it has been putting all efforts to achieve the
desired goals by implementing energy efficiency programmes like DSM-based
efficient lighting programme (DELP) for domestic households, said chief minister
N Chandrababu Naidu.
"As a first step, we have taken up replacement of inefficient sodium vapour street lights
with energy efficient LED (light-emitting diode) lighting system, which has been
recognised at the national-level. The Centre has also appreciated the energy efficiency
policies of the AP government and it is estimated that implementation of the DELP
programme alone will save around 500 Mw (or 12 million units per day)," he said.

According to him, so far 820,000 LED bulbs have been distributed in Guntur district
in Phase-I and is planned to be extended to the entire state," he said.

On the occasion of the National Energy Conservation (NEC) Day on December 14,
the state government released various posters highlighting the significance of energy
conservation and efficiency and impact of the government's programme of providing
LED bulbs at a nominal price of Rs 10 each as against the market value of around
Rs.400 through DELP.

Directing officials to take steps to replace inefficient/incandescent filament bulbs
with energy efficient LEDs in the housing sector in a phased manner by 2015-16,
Naidu emphasised the need to bring in LED revolution for phasing out
incandescent/inefficient bulbs and replacing them with LED bulbs.

At a price of Rs 204 each, LED lamp is just 30-40 per cent costlier than CFLs. As compared to CFLs, LEDs are 50 per cent more energy efficient. What’s more these do not use toxic mercury as is the case with CFL. Also, the life of an LED lamp is four to five times more than that of a CFL, and, therefore, it is a cheaper option on life cycle cost basis.
