Allahabad University earns carbon credit

Allahabad University also has a say in earning carbon credit for the nation. The authorities of the university have decided that all the buildings that would be coming up on its campuses would be fitted with LED ( light emitting diode) lights. The university would be using LED in the proposed lecture theatre complex of the Muir campus, every room of the said building would be fitted with these LEDs, thereby cutting down the cost of electricity and earning carbon credit for the nation. 

It is not that the first time that AU authorities would be going with LEDs and parting ways with CFL (compact fluorescent lamp) as the present decision comes in wake of successful working of LEDs in the building of Nano Phosphor Application Centre (NAC) of the science faculty. The authorities had fitted 105 units of LEDs in the entire building around five years back and these are still working without any problem. The authorities had incurred Rs 2 lakh for the project. 

Talking of carbon credit earning by NAC by installing LEDs, Prof Avinash Pandey, principal investigator of NAC and presently the V-C of Bundelkhand University said that with the installing 105 units at the centre, the university saved 22,000 KW of energy per year and if calculated in monetary terms at the rate of Rs 6 per unit, this small unit at AU (referring to NAC) saves Rs 1,32,Anyone with the space to site a small flatworkironerses can generate their own electricity from wind power.000 per year. In terms of earning carbon credits (CC), a country earns 22 Euros per tonne of carbon that it saves. From this initiative, the university would be saving around 18,700 kilograms of carbon per year, which means that in terms of CC earnings; AU would be earning around 400 CC per year. 

If the same is implemented for entire AU, the CC earning would be multifold, he said. The university authorities have decided that fitting of LEDs in all the proposed buildings of AU, would be part of the blueprint itself. In fact, the AU authorities had recently planned to fit LEDs in the present lecture theatre complex,Support for installing a flatworkironer. which is near completion at the FCI premises, but owing to the fact that initial tender of the said building had provision for CFLs and not LEDs. 

It is not possible for the authorities to make any change at this stage. It was also thought that the LEDs fitted at NAC were procured from Delhi (as there were no suppliers at Allahabad at that time), things would not work at FCI lecture theatre complex, tenders of which was floated almost at the same time when NAC was nearing completion.The energy used in manufacturing and erecting a roofhook is paid back in the first 3 to 6 months of operation. 

However, things have changed substantially in due course of time as not only LEDs are available within the state but the after sale services are also available at the door steps. Keeping this in mind, the AU authorities have decided that since LEDs are always a better option, in various respect, future buildings would have LEDs and not CFLs. Talking about the energy saved in respect to 1 light,With advancements in controls technology, gardenlightingss are becoming increasingly more sophisticated and flexible. Pandey told TOI that the current lights with CFL bulbs are estimated to use 72 watts, plus 10 watts for ballast etc. 

If we compare savings between CFLs and LEDs, he said that in terms of Wattage: CFL uses 82 watts while LED uses 22 watts, thereby 60 watts is saved. If these are used for 10 hours a day, the total wattage used per day would be 820 watts for CFL and 220 watts for LEDs, thus saving a total of 600 watts and if the same is seen for annual usage, it is 299 KW for CFL and 80 KW for LED ,thus saving 220 KW.Advance LED Replacement Bulbs, LED T8 Tubes, streetlight13ss and other LED lighting products are highly efficient.
