AP Environmental Science / Unit 6: Energy Resources and Consumption
6.7 Energy from Biomass
Notes
Biomass: burning wood, charcoal, crop waste, or making ethanol and biodiesel.
- Can be carbon-neutral in theory, but burning releases particulates and $\mathrm{CO}$; growing fuel crops uses land and water.
Practice
Burning wood indoors is a health concern because of:
Indoor air pollution.
Ethanol from corn:
Food vs fuel.
Biomass is considered "carbon-neutral" because:
In theory, absorption balances release.
