[Stoves] more on ocean acidification

[Crispin Pemberton-Pigott]

Dear Friends

 

Paul asks:

“Let us imagine an area in China where there is no biomass at all: no rice hulls, no rice straw, no agricultural or forestry residue of any kind. And let us suppose that in this barren landscape there is nothing but coal. Here I concede that it makes sense to focus attention on developing more efficient coal stoves.”

Let us imagine an area of any country where all the rice hulls, rice straw, agricultural and forestry residues of any kind are used for various purposes: building materials, fertiliser, fuel and mulch. 

In such an area it may be quite possible to fill energy shortfalls using coal. It may be possible to introduce energy and materials efficiencies that either increase the availability of energy or conserve it within the available supply. 

Coal, for example, being limited in availability, might make a very good interim fuel for Malawi where over-exploitation of the forest has cause all sorts of problems for almost everyone in the country while the forest recovers and sees better management. Of all the people who should be encouraged to burn coal for primary energy needs, Malawians are a good start.

Regards

Crispin
