Energy Efficiency Projects as Short-term Solutions to Combat Greenhouse Gas Emissions Within the Metals Industry
MetadataShow full item record
Over the last several decades, data collected by scientists across the world has indicated rapid mean temperature rise across the globe. This increase in global temperatures correlates with and has been attributed to elevated greenhouse gas levels in the atmosphere due to the reliance on fossil fuels for energy since the late 16th century. Focusing in on one of the largest energy consumers and emitters of greenhouse gases within industry, the metals industry was identified as a major area for the reduction of greenhouse gas emissions. In recent years, researchers within the U.S. Department of Energy and Lawrence Berkley National Laboratory have pinpointed several avenues to eliminate the emission of greenhouse gases from processes within the metals industry. However, these projects have yet to emerge as practical, large-scale, and economically viable options for most facilities within the metals industry. Smaller energy efficiency projects offer a stop-gap solution to reduce greenhouse gas emissions until more robust avenues for sustainability become practical. In this light, recommendations for effective energy management programs are provided along with the identification of practical energy efficiency projects common within the metals industry. Additionally, a call for further research into long-term solutions to eliminate greenhouse gas emissions is put forth to encourage future work within the area.
