Edit: read other later posts here: didn’t know about the bacteria part. Learned something today!&lt;p&gt;This is absolutely not my area of expertise but intuitively there are two categories of energy sources: one which releases co2 (or other climate change impacting gases) and one which doesn’t. Wood, oil, gas, coal falls into the former. It’s just a question of time as you say until the loop closes. Solar, wind, thermal, etc would fall into the latter as far as I can tell.</text><parent_chain><item><author>skrause</author><text>Technically coal is also a closed loop of carbon because the CO2 once came from the atmosphere.&lt;p&gt;Which brings us to the problem: The CO2 shouldn&amp;#x27;t be in the atmosphere &lt;i&gt;right now&lt;/i&gt;: If you burn wood today and the CO2 gets removed again by new plants within the next 100 years, that&amp;#x27;s still a problem.</text></item><item><author>woodisgood</author><text>Is wood not a renewable resource?
