All Flashcards
Why is sustainable management crucial for biomass?
Prevents deforestation, habitat loss, and species extinction.
Explain the carbon cycle relevance to biomass.
Biomass utilizes carbon already in the cycle; sustainable use maintains balance.
How does biomass relate to renewable resources?
Waste is continuously produced, making it a renewable resource if managed well.
Explain why location matters for biomass energy.
Biomass is practical where other energy sources are limited due to wide availability.
What are the environmental consequences of deforestation?
Habitat loss, soil erosion, reduced biodiversity, and climate change.
What are the effects of burning biomass?
Releases CO2, carbon monoxide, nitrogen oxides, particulates, and VOCs.
What is the effect of unsustainable biomass use?
Deforestation, habitat loss, and potential species extinction.
What are the effects of using ethanol as fuel?
Reduces reliance on gasoline, but production can have environmental impacts.
What is the impact of biomass power plants on local economies?
Job creation, local energy source, but high initial investment costs.
What is the effect of using landfill gas for energy?
Reduces methane emissions, generates electricity, and reduces reliance on fossil fuels.
What is the effect of using crops as biomass?
Reduces agricultural waste, generates energy, but can compete with food production.
What is the effect of over-harvesting trees for biomass?
Deforestation, habitat destruction, soil erosion, and reduced carbon sequestration.
What is the impact of biomass production on air quality?
Combustion releases pollutants like CO2, NOx, particulates, and VOCs, affecting air quality.
What is the effect of using sustainable biomass practices?
Reduced deforestation, habitat loss, and carbon emissions, promoting long-term sustainability.
How can sustainable forestry improve biomass energy?
Maintains forest ecosystems, ensures continuous biomass supply, reduces deforestation.
How does using agricultural residues promote sustainability?
Reduces waste, provides energy source, minimizes land use for dedicated crops.
How does capturing landfill gas help the environment?
Reduces methane emissions (potent greenhouse gas), generates energy.
