This paper presents an economic framework for integration of energy efficiency and renewable energy in manufacturing plants that results in net-zero carbon emissions at net-zero costs. The paper begins by reviewing the economics of net-zero energy buildings and discussing why a different approach is needed for manufacturers to significantly reduce carbon emissions. The manufacturing paradigm capitalizes on the energy intensity of manufacturing and recognizes that on-site net-zero energy is not consistent with the production of energy-added goods. Net-zero carbon manufacturing begins by applying the integrated systems plus principles approach to energy efficiency that provides a coherent, reproducible and teachable method to improving manufacturing energy efficiency. The savings realized from energy efficiency improvements are used to first make investments in onsite renewable energy, and subsequently to purchase Renewable Energy Credits. The result is that net-zero carbon emissions are achievable for most manufacturers at net-zero cost, in a manner that is consistent with manufacturing business practices. The paper demonstrates this method with case-study data from manufacturing energy assessments.
