# Bioethanol and Biomass

Energy flows from biomass to bioethanol; their prices have moved together.

[Bioethanol](https://www.materialinsights.org/energy/bioethanol/) (chemical) and [Biomass](https://www.materialinsights.org/energy/e_biomass/) (energy): 2 relationships.

## How they are linked

### 1. Energy flow

*Physical flow · 4.5% of flow · Biomass → Bioethanol*

Sugar and starch crops are fermented into ethanol.

- **4.5%** of Biomass's energy goes this way

### 2. Price link: competing use

*Cost and price · Weak · Both ways*

Biomass can be fermented into ethanol rather than burned, and ethanol made from maize or cane competes for crops and land. The US indices show a weak link: monthly moves correlate at -0.06 and yearly moves at 0.30.

- **-0.06** monthly change correlation
- **0.30** 12-month change correlation
- **0.17** fitted elasticity
