This book addresses the issues, intricacies, and challengesrelating to energy and environmental sciences. Papers cover varioustechnological aspects of sustainable energy eco-systems andprocesses that improve energy efficiency, and reduce andsequestrate carbon dioxide (CO2) and other greenhouseemissions. The collection also emphasizes the need for sustainabletechnologies in extractive metallurgy, materials processing andmanufacturing industries with reduced energy consumption andCO2 emission. Industrial energy efficient technologiesinclude innovative ore beneficiation, smelting technologies,recycling and waste heat recovery. The book also carriescontributions from all areas of non-nuclear and non-traditionalenergy sources, including renewable energy sources such as solar,wind, and biomass. Papers from the following symposia are presented in thebook: Energy Technologies and Carbon DioxideManagement High-temperature Material Systems for Energy Conversion andStorage Solar Cell Silicon
