Reply to comment by ErkMcGurk in I want to get off the grid. What are my options for heat and hot water? by pencil_2b

There’s only so much waste wood and it can also go to particle board. Burning pellets will always pull from a market that also makes pellets out of forests. It’s only carbon neutral on long time frames, if you cut down a tree and plant a new one in its place, it takes a century to catch up.

Ok, wood comes from trees that got cut down, but is it actually a worse energy source environmentally-speaking than photovoltaic? While growing, trees provide food and habitat for wildlife, and require little maintenance to produce. PV solar, besides the environmental costs of producing the panels themselves, also depends typically on lead or lithium-based batteries, and all of the equipment needs to be replaced on a regular basis (5-10 years for batteries, 25 years for panels). Large-scale solar farms often occupy space that trees could instead, and I wonder whether the trees would be more efficient at capturing solar energy.

I'm sure improvements could be made in the forestry industry, but wood burning seems to be less of an environmental concern than burning fossil fuels, and is an economical source of heat in areas where wood is abundant.
