• Geopolymer - says 48% higher embodied energy than Portland? [3]

Materials

• Wood - 8.5MJ/kg

Specific - Energy of Production

• 14-17 kWhr are used for producing 1 kg of PLA plastic 3D printing filament! See excellent industrial ecology paper, p. S84 at [4]
• Note that this is the same amount of energy as that required to smelt 1 kg of aluminum from aluminum oxide!
