Interesting that the tables show electricity from a Solar PV mini grid uses
less power and total energy per meal compared with other fuels, paraffin
seems to perform particularly poorly (why?). Most electricity is derived
from another primary fuel so in other cases the energy cost of the fuel
used to generate the electricity and transmit it needs to be in the account.

I don't understand the objection to "stacking", is it just that  if less
clean cooking appliances are used as well as the cleaner ones the
improvement is simply not good enough?
