Solar Cooker

At Barli…

Solar cooker in our school: The solar cooker costs Rs. 70, 000. Solar Cookers can be effectively used for cooking Dal and Rice in our school. If we install solar Cookers we will be able to save 25 cylinders of LPG per month.

Solar Water Heaters

The cost for installing the solar water heater for Holkar house – 4. 5 lakh The cost for installing the solar water heater for Malwa house – 3. 5 lakh = 8 lakh (Additional 50 thousand is required for plumbing) that sums up to 8. 5 lakh

In Daly College there are 800 boarders. We worked out estimates for hot water required for bathing for two boarding houses which have a total of 300 students. Each student / day requires 15 litre of hot water of 70ºC. Electricity consumption → Q = MST Where Q is in kilo calories M = Mass (in Kg) S = Specific heat of water = 1 T = ΔT it is the change in temperature. ΔT for 70 ºC = 50ºC Q = MST = 15 X 1 X 50 = 750 kilo calories = 0. 87225 k. Wh For 300 students we will be saving energy/day = 0. 87225 k. Wh X 300 = 261. 675 k. Wh For 300 students we will be saving energy/year (205 days approx) = 261. 675 x 205 = 60, 000 k. Wh

Bio Gas Plant

Proposed Site….

1 kg of food waste 250 gm of LPG Waste produced per day 100 kg Methane gas generation 25 kg (100 x 250 gm) per day Total requirement is 60 kg of LPG per day 1/3 rd of our LPG consumption

What Difference our Initiatives will Bring Initiatives Electricity Units: - CO 2 emissions reduced High Tension Wiring Low Loss Type Transformer 23. 040 MWh/year 14, 592. 94 lb Underground Power Cabling 46. 080 MWh/year 29, 171. 22 lb Solar Water Heating 60. 000 MWh/year 38, 000 lb Total 129. 120 MWh/year 81, 764. 16 lb Total Money Saved in a Year= 129. 12 x 5000= Rs 6, 45, 600

Initiatives LPG Consumption is reduced by Money Saved in a year Solar Cooking 11. 83 x 365 =4317. 95 Kg/year 4317. 95 x 23. 3= Rs 1, 00, 346 Biogas Digester 25 x 365 = 9125 Kg/year 9125 x 23. 3 = Rs 2, 12, 612 Total Money Saved in a year = Rs 3, 12, 612
