Ethanol from sugarcane has a medium net energy yield, while ethanol from corn has a low net energy yield. Why might this be the case? The energy input for growing corn is lower than that for sugarcane. The energy input for growing sugarcane is lower than that for corn. The EROI for corn ethanol is higher than that for sugarcane. The net energy ratio of corn ethanol is negative. Corn ethanol is not a renewable energy source.

Energy Flow

Energy flow is the continuous and directional flow of energy through living beings within an ecosystem. All living beings can be segregated into producers and consumers. These producers and consumers can be further divided in a food chain. The term ‘trophic level’ is assigned to each level of the food chain.
