[Stoves] EEG = Energy Expenditure Groups. was Re: grid poweredstoves

[Crispin Pemberton-Pigott]

Dear Paul

Many thanks for the comprehensive response.

The answer to a great number of your questions is, 'Yes.'

The EEG1-10 groupos are representative of the income groups used in South 
Africa to analyse what people spend their income on and why, and what they 
are willing to do to save money, and how much they can afford to spend to 
earn that saving.

They use something called Living Standards Measure or LSM.  The income 
groups are not directly related to what we are doing so I used something 
that covered a range we are likely to encounter in our work.

>per day ($300 per month)

The important is not that they spend 5% of their income on energy for 
cooking, it is that they have enogh money to spend on a device that would 
save money, and that they spend a total of $15.

If the product you are trying to sell will save 1/2 of that expenditure, how 
much are they willing to spend on a device (that also has attractive 
features perhaps...) to realize that saving?

Thus the EEG level is the attaction, or the measuring stick.

People who spend little but earn very little are attracted to low cost 
solutions for generating savings.

I will write more later re your other questions.
