HOW CAN I SAVE ENERGY?
 
EFFICIENT STOVES
 
Did you know that all cooking stoves are not equally efficient? Some waste energy unnecessarily, whereas others save energy. Following is a list that would help you pick a cook stove to suite your budget.

87% of households use fuel wood for cooking
84% of the total LP gas consumed goes for domestic applications.
Yet, due to preliminary technologies in using fuel wood and inefficiencies in LPG usage, a huge amount of energy waste occurs in household cooking.

 
The Traditional three-stoned hearth
 
 
 
Very low efficiency – 5 – 8 %
 
Anagi stove
 
 
Efficiency – 17 – 20 %
Efficiency can be maximised by
  • Utilising both burners at once
  • Burning wood chips
  • Pairing burners with proper sized utensils
  • Ensuring adequate ventilation

Efficiency can be maximised by 
  • Using wood chips with low moisture content
  • Packing woodchips to ensure adequate ventilation
 
LPG cookers
 
Efficiency – very much high compared to fuel wood stoves
 
 
Efficiency can be maximised by
  • Adjusting the burner to get a blue flame
  • Using pressure cookers, stainless steel utensils 
  • Pairing burners with proper sized utensils
  • Minimising the height between the flame and pan
  • Keeping burners clean
