Wonder how much energy is needed to produce the carbon fibre, LH...

Wood is renewable - and providing some forest managment (replanting etc.) is done (not jut felling the trees and leaving the land to beef producing)there is no grat damage done. Still the transportation of tropical woods uses energy as well. One could use only local wood but that would leave dveloping countries with less income...

This issue is kind´a complicated, isn`t it?
