  • Embodied energy Wikipedia

    Embodied energy is the sum of all the energy required to produce any goods or services, considered as if that energy was incorporated or 'embodied' in the product itself. The concept can be useful in determining the effectiveness of energy-producing or energy saving devices, or the "real" replacement cost of a building, and, because energy-inputs usually entail greenhouse gas emissions, inEnergy to Waste? Solid Waste & Recycling Solid Waste,Apr 01, 2000· To put the energy embodied in these cans into perspective, consider that Ontario’s Pickering nuclear station generated about 13.1 TWh in 1999.
