All Flashcards
Why is biomass considered renewable?
Waste is continuously produced, replenishing the source.
What is the role of biomass in carbon cycle?
Biomass combustion releases CO2, but sustainable practices aim for carbon neutrality.
What are the sustainability concerns of biomass?
Over-harvesting leads to deforestation and habitat loss.
Why is location important for biomass?
Biomass is practical in areas with limited access to other energy.
Why is the EROI of ethanol important?
It affects the overall sustainability of ethanol as a fuel.
Why is sustainable management crucial for biomass?
To prevent deforestation and habitat loss.
Why is biomass considered carbon neutral?
Burning it doesn't add new carbon to the atmosphere.
What are the limitations of biomass?
Produces pollutants and can lead to deforestation.
What is the importance of biomass regeneration rates?
They determine the sustainability of biomass use.
What are the benefits of biomass energy?
Widely available and can be carbon neutral.
How can sustainable harvesting protect environment?
Maintains forest cover and biodiversity.
How can using waste biomass help protect environment?
Reduces landfill waste and methane emissions.
How can improving EROI of ethanol help protect environment?
Makes it a more sustainable fuel source.
How can reforestation help protect environment?
Restores habitats and sequesters carbon.
How can using biomass for local energy help protect environment?
Reduces reliance on external sources.
How can using biomass for local energy help protect environment?
Reduces reliance on external sources.
How can sustainable practices help protect environment?
Maintains habitat and biodiversity.
How can reducing reliance on fossil fuels help protect environment?
Reduces greenhouse gas emissions.
How can job creation in harvesting, transportation, and plant operation help protect environment?
Local energy source, reducing reliance on external sources.
How can job creation in harvesting, transportation, and plant operation help protect environment?
Local energy source, reducing reliance on external sources.
What are the effects of over-harvesting biomass?
Deforestation, habitat loss, soil erosion, reduced biodiversity.
What are the effects of burning biomass?
Releases CO2, CO, NOx, particulates, and VOCs into the atmosphere.
What are the effects of using ethanol instead of gasoline?
Reduced reliance on fossil fuels, lower carbon emissions (potentially).
