Wood pellet stoves may not have the romance of a log fire or solid fuel stove (my parents just got a Rayburn, which I haven’t seen yet, but they’re surrounded by a near free supply of downed trees and off cuts), but they could be as near to carbon neutral as an energy solution gets.

A few thoughts-

How are the factories making these pellets powered?  If they can close the circle and have a combined heat and power system on site powered by some of the pellets produced that will be brilliant.

The fuel will never be entirely carbon neutral until the chainsaws are powered by ethanol and every vehicle used runs on biodiesel.  But that’s being picky, it’s still a hell of a lot closer than anything else, and they could always plant excess trees to offset production costs.

How clean do these stoves burn?  A lot of Britain is now smoke-free zone, which has to hinder the uptake of solid fuel.  I imagine as they become more efficient the stoves create less smoke.
