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 lakhThe 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 kWh
For 300 students we will be saving energy/day = 0.87225 kWh X 300
= 261.675 kWh
For 300 students we will be saving energy/year (205 days approx) = 261.675 x 205 = 60,000 kWh
Bio Gas Plant
Proposed Site….
1 kg of food waste 250 gm of LPG
Waste produced per day
100 kg
Methane gas generation per day
25 kg (100 x 250 gm)
Total requirement is 60 kg of LPG per day
1/3rd of our LPG consumption

What Difference our Initiatives will Bring
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 =
