    Because of thermal efficiency of combustion cycles? Turbines are only like 30% to 40% efficient largely because of thermodynamics.

      In large power plants, e.g. block D of natural gas power plant Emsland, you can get almost 60 %, but that’s neither the standard for power plants, which was like ~28 % in Germany a few years ago, nor is the technology applicable for small scale devices as e.g. car engines.
