Today i along with two of our my student climate members , Tenzin Dhonden and Palgon Tsering  went to the school's boys hostel to replace the incandescent lamp by compact fluorescent lamp . Actually some days before i have already noted down the electrical energy consumed in by the boys hostel in one day . The electric meter reading shows that it in one day electrical energy consumed is 29.2KWH or units . So that was before replacing the incandescent lamps by the CFL. SO today i have  taken the reading just after replacing the incandescent lamps by the Compact Fluorescent lamps at 3 : 15 PM . There are three electric meters for the boys hostel whose readings show ( meter 1 : 31005 KWH ,  meter 2 : 4582.7 kwh, Meter 3: 11756 KWH) . My student Dhonten , he is a quick learner and also stays at hostel told me that  he will take the readings of the electric meter tomorow exactly at 3: 15 pm . So by subtracting the today's reading from the tomorow's one , we will get the electrical energy consumed by the boy's hostel in one day . So keeping our fingers crossed , coz tommorow we expect the total electrical energy consumed to be much less than 29.2KWH . lets wait and see . I am going to put the result in the diary on Monday ie. 19/X/09
