Bio-energy system analysis: Profit, planet, and policy
… the shift from a fossil-based economy to a bio-based economy as one of my many options. A bio-based economy refers to an economy that utilizes biomass for the production of goods, services, and energy. Using biomass leverages the biogenic carbon cycle of biomass, which can lower total …
