Energy, exergy, exergo‐environmental, and exergetic sustainability analyses of a gas engine‐based CHP system

Abstract The electricity demand is ever increasing, and the worldwide power generation is largely dependent on the rapidly dwindling fossil fuel resources. It is no different in Bangladesh as well where the prevailing dynamic in the energy sector projects to a certain lack of sustainability. This ma...
