Study Guide Overview
This study guide covers biomass energy, including its definition as the burning of organic matter (wood, garbage, crops, landfill gas, alcohol fuels) for heat and electricity. It explores the types of biomass, sustainability concerns like deforestation and regeneration rates, and the use of ethanol as a fuel, highlighting its carbon neutrality and EROI. The guide also discusses benefits and drawbacks of biomass energy, advancements in biomass technology, and key concepts for the AP Environmental Science exam, including practice questions covering environmental and economic impacts.
#Biomass Energy: Powering the World with Waste 🌱
Biomass energy, one of humanity's oldest energy sources, involves burning organic matter like wood, crops, and waste to generate heat and electricity. Let's dive into how this works, its pros and cons, and its role in our energy future.
#What is Biomass Energy?
Biomass is essentially the burning of organic matter to produce heat, which is then converted into electricity. It's a renewable resource because waste is continuously produced.
#Types of Biomass
- Wood: Traditional source, but over-harvesting can lead to deforestation.
- Garbage: Municipal solid waste can be burned for energy.
- Crops: Agricultural residues and dedicated energy crops.
- Landfill Gas: Methane produced by decomposing waste.
- Alcohol Fuels: Ethanol and biodiesel.

Biomass resources are widely available, making them a practical option, especially in areas with limited access to other energy sources.
#Sustainability Concerns
While biomass is renewable, it's crucial to manage it sustainably. Over-harvesting can lead to deforestation and habitat loss. ...
