Abstract—To meet the growing energy demand, there is a need to develop advanced energy systems to utilize coal, natural gas and biomass with higher energy conversion efficiency. On the other hand we need to conserve the energy resources in an efficient manner. There is also growing interest to develop renewable energy sources such as wind, solar, biomass on one side and on the other side to develop efficient and sustainable energy technologies to utilize coal and natural gas in an environmentally sustainable approach. In the present paper the developments in advanced energy systems and energy management measures are discussed.

Index Terms—Combined cycle, efficiency, energy conversion, waste heat.
