efficiency of plants - 1%

efficiency of photovoltaic - 20%

so photovoltaic is 15 times more land efficient then burning biomass. so we absolutely need trees to provide ecological functions. but in era of 5kwp PV array paying itself in 5-6 years(and still working afterwards), to heat water... its is ridiculous to cut trees and burn them to have hot water. 80% of time Canadian citizen can have 100% solar hot water (PV), less then 100% rest of the year.

It's always ridiculous to cut trees for firewood. There is no need, since there is so much dead firewood lying around, and so many trees die every year, and since most people use much cleaner natural gas for heating. As for oil and gas, those are still cheaper, denser, and more portable -and even more sustainable when you consider the mining for rare earths and lithium- than any renewable energy source.

Green trees are not used for fire wood or for paper. Burning green wood makes for terrible fire wood it also causes issues with chimneys due to having more Creosote.

It is illegal In The logging Industry to use merchantable wood for paper or fire wood. Wood has grades and graded wood is worth a lot more than fire or paper wood. Paper wood also has a grade but it is a low grade. Often firewood can be shipped to paper mills as an example.
