RE: Convent fuel for remote locations - C3

[Raili Kajaste <Raili.Kajaste@rintekno.fi>]

Propane is an efficient fuel for remote locations. However, when we are
concerned about global warming and greenhouse gases, propane is a fossil
fuel that releases to atmosphere CO2 each time when burned/fired.

As for supply infrastructure, there are certain safety risks related to the
use of propane balloons in hot climate, and the transportation of propane to
filling stations causes additional harmful emissions. Especially,  small
particulates, CO2 and aromatic hydrocarbons.

I would primarily try to opt for renewable energy resources like briquetted
wood waste in combination of manure etc.
