Its also been said that smaller diameter bamboo dries faster than larger diameter trees. Bamboo is a type of grass. Which could translate to it being more carbon neutral in contrast to most trees. Bamboo can also be used for many other applications aside from firewood. Which makes it a good investment even if the firewood application dries up, eventually.
The article mentions that burning wood releases toxic chemicals. Burning termite treated lumber will release arsenic fumes into the air. I'm not certain about naturally grown wood having toxic substances however.
Bamboo trees are a very good source of heat considering their short maturity period, less toxic nature, and ability to dry fast. But it doesn't have the ability to retain heat for a long time. One needs to have plenty of it to heat a house for a very long time which might increase the amount of fume and ashes produced.
Bunning itself releases toxic substances and it is very obvious that even natural grown woods are also toxic. Research showed that harmful substances suchbenzene and dioxins are by-products of natural wood burning.
Already the country is experiencing drought situation. This too a big problem as water levels fall to below 40cm on Rhine river, the route of transporting fuel and other necessary commodities. This is supposed to fall even lower and the same have made the ships to reduce the loads. The heat of the water is very high and this leads to death of fishes and floating all around. The climate change is being experienced in a large scale. Now for the lack of required fuel people moving towards the firewood leads to deforestation. The same could have its effects on the environment over time.
Yes, Europe is in dire need of an alternate source of heat and any option would be accepted regardless of the effect on the environment. But it was the same EU that portrays itself as the champion of the environment. They claim to love the environment and that they can do anything to preserve it. They would quickly point accusing fingers at Bitcoin as one of the enemies of the environment. The question now is where is the love?
