Is burning wood the same as letting it biodegrade from a CO2 emissions perspective?

Conservation It is a fundamental law of physics that matter/mass/energy (all being, ultimately, the same thing) cannot be created or destroyed — they just change form. Under 'normal' conditions on ...

Can kiln-dried wood be stored outside?

Yes you can store it outside. That said, your practice is less than optimal. KD wood is normally dried to something like 12% moisture content. Air dried wood will eventually reach a level between ...

Size of wood lot required for cooking/heating (US west coast)?

OK, one possible setup (and assuming both my math and memory are right, neither of which is certain): Planting Douglas Fir, which is fairly fast growing (one to two feet a year) and a good wood for ...

CO2 emissions from outdoor fire pit

The Short Answer Burning 1 kg of wood releases 1.6 kg of CO2. (source: EPA) I'm not sure how big your 2-3 logs are, so I'll just say that 5 kg wood is probably enough to make a reasonable outdoor fire ...

Size of wood lot required for cooking/heating (US west coast)?

I've done this calc for my farm here in Alberta. I know that it takes 5 cords a year to heat my house. The average lifespan of trembling aspen is about 40 years. At that point it's about 40 feet ...

Burning wood efficiently via rocket stove

Yes. Moz's comment is correct. When burning wood, you are in essence just shortcutting the rot process. Which means that instead of fungi and bacteria and bugs getting lunch, you get warm. These ...

Is burning wood the same as letting it biodegrade from a CO2 emissions perspective?

Yes and no. The answer to the question you asked is yes. Biodegradation produces carbon dioxide and heat. The heat of biodegradation will be wasted. It makes much more sense to usefully harvest the ...

Is burning wood the same as letting it biodegrade from a CO2 emissions perspective?

The simple answer is that burning it would be roughly carbon neutral (it releases what it absorbed during growth) versus letting it decompose where it would be a carbon sink. Fossil fuels in the ...

How much firewood does it take to produce the equivalent of 1kWh of electrical heating?

Efficiency numbers are, unfortunately, misused/abused by companies that manufacture and sell wood heaters. "Combustion Efficiency" is not actually a direct measure of how much heat is produced by ...

How much firewood does it take to produce the equivalent of 1kWh of electrical heating?

Per Google, 1 kWh = 3412 BTU. (And a fraction, which I'll neglect.) Here's a table (one of many found with Google) of BTU/cord for various kinds of wood: https://chimneysweeponline.com/howood.htm ...

How much wood can I burn sustainably, carbon neutral and in an ecologically responsible way from a forest?

To be ecologically truly sustainable, no live trees should be cut. That will most closely mimic a natural ecosystem instead of turning them into managed tree plantations (which ain't properly forests)....

Is burning wood the same as letting it biodegrade from a CO2 emissions perspective?

I think a review of photosynthesis is in order. The CO2 plants take in are actually stored as sugars. Burning this will release it, but wood that decomposes naturally would have those sugars broken ...

NO, not when you add "efficient" to the question. Certainly it is possible ,however efficient is the catch and everyone will not have the same definition. I suggest look up wood gasification ...
