Here is similar data from Sweden: https://www.researchgate.net/profile/Egnell-Gustaf/publication/236656238/figure/fig6/AS:668498074275840@1536393769085/Production-of-energy-petajoule-from-biomass-peat-and-solid-waste-in-district-heating.png https://www.researchgate.net/profile/Egnell-Gustaf/publicati... Here is for the world, my understanding is that "Traditional Biomass" is mostly firewood there too: https://ourworldindata.org/exports/global-energy-substitution_v4_850x600.svg https://ourworldindata.org/exports/global-energy-substitutio...
