Wood burning contributes unnecessarily to deforestation and emits a lot of air pollution, things people used to think were no bueno.
- millstone 6y agoWood pellets are efficient, produce low pollution, and are one of the most renewable fuels.
- dr_dshiv 6y agoMind blown. Yet, Life Cycle Analyses show conflicting results. Here is a recent review. Would be very good to know whether this has potential as a future biofuel. https://www.sciencedirect.com/science/article/pii/S1364032120305669?casa_token=Lx5In3Xs1ScAAAAA:tw9ybNRqT3vZDtz_FI698oaBCDw-KwLSuRvpoOvd_FWNZHi7haZHm9ZWjmYs8ytXAZDsj3p85Ic#sec5 https://www.sciencedirect.com/science/article/pii/S136403212...
- millstone 6y agoIn our best future we grow trees and log them for construction, storing their carbon. We process the waste branches, bark, etc. into wood pellets which get burned, displacing the use of fossil fuels. There's very real questions about how wood pellets are sourced, but moving from burning ancient fossils to burning recent trees has to be directionally correct, part of the solution.

- 7952 6y agoLower pollution compared to burning logs perhaps. But still much higher than a modern oil or gas heating system.
- magicalhippo 6y agoMy cabin, which was put up by my grand parents, has a picture of the view back in the 50s. When comparing it to the view outside today it's easy to see the treeline has moved up hundreds of meters in altitude. Mountains that were bare are now part of the forest. Not saying we should promote wood burning, but I'm not tossing out the old wooden stove.
- m463 6y agoI thought it was thinner air that caused the treeline, is it temperature? or is it air, which just has more CO2?
- throwaway5752 6y agoIt's temperature. Which, of course, is because the air has more CO2.
- Ma8ee 6y agoTemperature. The tree line moves down the further north you go.
- magicalhippo 6y agoThere are primarily two factors are driving it. People and especially farmers have changed how they use the land. There are much less animals grazing, thus not keeping forests in check. As mentioned temperatures have also increased, which allows trees to grow at an higher altitude than before. Here's a relatively recent news article about this[1], including a couple of images of the same place 50 years apart showing the progress.

- dredmorbius 6y agoAnd yet it remains in use in many places. As the article notes, a properly-designed stove with forced draft and postcombustion airflow could reduce both fuel use and pollution. In theory. I'd like to see this actually tested.
