prve co som vygooglil ta nepotesi

"Researchers estimate that, in total, wood may produce between three times and 10 times fewer greenhouse gas emissions per unit of heat than other energy sources"

v praxi to vyratat je ale nemozne. ak sa budeme bavit o kotloch (a nie o elektrine), kazdy ma iny kotol, komin, ine drevo. dokonca aj zlozenie a teda vyhrevnost plynu kolise (v priebehu roka 2015 to kolisalo okolo 3%)

Čo tým myslis?
