概要	Exergoeconomic analysis combines thermodynamics and economics by assigning monetary costs to exergy streams. It reveals how thermodynamic irreversibilities translate into economic losses within industrial systems. This approach enables engineers to identify the most economically significant inefficiencies and make informed decisions about component improvements and system optimization.	Exergoenvironmental analysis extends exergy-based methods to quantify and allocate environmental impacts of thermal systems. It assigns environmental costs to exergy streams based on upstream lifecycle impacts, revealing which components contribute most significantly to environmental burdens. This enables engineers to design sustainable energy systems by optimizing the trade-off between thermodynamic and environmental performance.	Levelized Cost of Energy (LCOE) is a standardized metric that spreads the total lifecycle cost of an energy project over its lifetime energy output. It enables fair comparison of electricity generation technologies with different capital structures, operating costs, and lifetimes. LCOE is widely used for technology evaluation, investment decisions, and energy policy analysis.	The Rankine Cycle is the fundamental thermodynamic cycle for steam power plants. It describes how thermal energy from burning fuel or concentrated solar radiation is converted to mechanical work and ultimately electricity. The cycle consists of four processes: isobaric heat addition in the boiler, isentropic expansion through the turbine, isobaric heat rejection in the condenser, and isentropic compression by the pump.
