Dear Mark,

 

I would be interested in receiving a copy and possibly to correspond with
you about questions I might have. Thank you, A. Klingshirn

All, 

 

I wanted to bring to your attention our (Nathan Johnson and I) most recent
journal article on cookstoves, "Factors affecting fuelwood consumption in
household cookstoves in an isolated rural West African village" which was
published this month in the journal Energy. Here is the abstract

 

----------

Abstract -- This study examines the factors that affect fuelwood consumption
in cookstoves and estimates fuelwood consumption associated with the use of
cookstoves in a rural isolated West African village with a population of
770. Five primary applications of cookstoves were identified: cooking meals,
heating water for washing, roasting peanuts, making medicine, and steeping
tea. Six factors were identified that significantly impacted cooking energy
use: the type of cookstove application, family size, total mass of wet and
dry ingredients, mass of dry ingredients, the use of burning embers as an
igniter, and the number of fires used during a cooking event. Annual village
fuelwood use for all cookstove applications was 234 metric tons; cooking
meals and heating water accounted for 65% and 27% of this fuelwood use,
respectively. Fuelwood consumption per person was strongly linked with
family size. As family size increased from five to twenty members, fuelwood
consumption decreased from 20.6 MJ cap-1 day-1 to 10.5 MJ cap-1 day-1.

To my knowledge this is one of the few studies to look at a single village
for a period of a year, ask the question "what factors affect wood
consumption?" and then develop an estimation methodology for household
energy use for domestic cookstove applications. Two of the more interesting
conclusions were (1) that stove stacking was very common and as a result
improved stoves did displace traditional stoves but rather supplemented them
and (2) as a result improved stoves did not reduce wood usage at a
statistically significant level. I would note that the number of improved
cookstoves was small and so a larger sample may find statistical
significance, nonetheless the results are interesting and indicate that
stove stacking should be considered in our stove programs.

 

Do to the publisher's copyright restrictions I cannot post the full paper
for open download. If you have no cost access to Elsevier journals, the full
paper is available at

Alternately, if you do not have no cost access to Elsevier journals and
would like a copy I would be happy to send you an electronic copy of the
full paper at no charge, just drop me an email.

 

And of course if you comments or questions, just let me know. 

 

Best regards

Mark
