Suggestions on the bionergy research, such as increasing biomass resources, improving biomass processing techniques and energy transfer efficiency, are recommended.
Energy conversion efficiency (η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be electric power, mechanical work, light (radiation), or heat.
