-Wood used to be the traditional primary energy source of all people for Millenia until the industry nations started to rely heavily on coal, followed by the electrification of households. On the other hand, many developing nations still rely on fuelwood as primary energy source. Therefore, the first step is to find multiple sources to assess, how much wood was, is and is going to be used as primary energy source in households worldwide.+Wood used to be the traditional primary energy source of all people for Millenia until the industry nations started to rely heavily on coal, followed by the electrification of households. On the other hand, many "developing" nations still rely on fuelwood as primary energy source. Therefore, the first step is to find multiple sources to assess, how much wood was, is and is going to be used as primary energy source in households worldwide.

-Although newer data indicates, that the consumption levels are lower than the 1990 projections, all projections have one thing in common: Unless humankind develops alternative, sustainable & clean energy sources, available to //everyone// worldwide, fuelwood will continue to be the only available energy source for more than a quarter of the population on the face of the earth. These people rely on it to survive and have no alternative to seize, in order to minimize the impact their actions may have on their environment for at least another 20 years. +Although newer data indicates, that the consumption levels are lower than the 1990 projections, all projections have one thing in common: Unless humankind develops alternative, sustainable & clean energy sources, available to //everyone// worldwide, fuelwood will continue to be the only available energy source for more than a quarter of the population on the face of the earth.
