Is wood a renewable or non-renewable source of energy and why?

Wood is a renewable but limited source of energy, as you would consume it faster than it is replenished. The CO2, soot and other elements released, not to mention the accompanying deforestation, also makes burning wood for energy environmentally unsound.

Wood is renewable because new trees can be grown.

I heat with wood, most of which comes off my property.

It is a renewable energy source since for every tree you
burn another can be grown. I would suggest you check out www.renewableenergyhub.co.uk/ for more information.
