From NOT A LOT OF PEOPLE KNOW THAT

Wooden pellets are sometimes considered as a substitute, climate-friendly vitality supply, particularly for heating. However an evaluation reveals this isn’t the case in any respect.
CO2 emitted [kg]. Information supply: German Ministry of the Setting
Although it’s claimed that the CO2 from burning biomass like timber stays within the pure carbon cycle, the CO2-absorbing timber are sometimes commercially chopped down, pelletized and burned, thus emitting years price of CO2 sequestration in only a matter of hours. Stay timber recapturing that very same emitted CO2 and storing it within the type of biomass takes a long time.
Wooden emits essentially the most
How a lot CO2 does the manufacturing of 1 megawatt-hour of vitality emit by totally different fuels? That is answered at FB by the account Umwelt- und Klimathemen. They write:
Isn’t it nearly the identical whether or not I burn wooden from a 150-year-old oak tree in pellet type in my heating system or whether or not I burn coal that has been within the floor for hundreds of years? Each the wooden and the coal launch the carbon dioxide they as soon as filtered out of the air after they burn.
In response to the German Ministry of the Setting, burning wooden produces much more carbon dioxide than fossil fuels akin to coal and fuel.
– 202 kg of carbon dioxide for pure fuel
– 340 kg carbon dioxide for laborious coal
– 403 kg carbon dioxide woodenHowever for the local weather, it doesn’t matter the place the carbon dioxide comes from!
That’s why heating with wooden is just not local weather impartial!
Even when we make pellets from our wooden, it’s nonetheless wooden that enriches our ambiance with carbon dioxide when it’s burned.”
Wooden emits double the CO2 that pure fuel does. By no means thoughts the particulates burning wooden entails.
