Question

categorization 10 points
2 determine if each statement is fact or fiction for biomass energy.
fact
releases greenhouses gases that increase air pollution and contribute to global climate change
allows people to repurpose waste for energy production
fossil fuels are currently used to harvest many crops and process plant waste before it can be used as fuel
fiction
can only be used in a limited area of the world
biofuels can only come from dead matter
generates more energy than fossil fuels
can only be used in large scale power plants for fuel
is a renewable energy resource

Explanation:

• Fact:
• "Fossil fuels are currently used to harvest many crops and process plant waste before it can be used as fuel": This is a factual statement as fossil fuels are indeed used in agricultural machinery (for harvesting crops) and in some industrial processes (related to plant waste processing).
• "Allows people to repurpose waste for energy production": Biomass energy (a form of which is plant - waste - based) does allow waste repurposing for energy, which is a known fact.
• "Releases greenhouses gases that increase air pollution and contribute to global climate change": Biomass combustion (a way of using biomass energy) can release greenhouse gases (though in a more carbon - neutral cycle compared to fossil fuels in some cases, but still a factual release of such gases).
• Fiction:
• "Is a renewable energy resource": Biomass is a renewable energy resource as plants can be regrown, so this is a fiction (it should be a fact. Maybe there was a mis - categorization in the original setup).
• "Can only be used in large scale power plants for fuel": Biomass can be used in small - scale applications like home - based biomass stoves, so this is a fiction.
• "Generates more energy than fossil fuels": In general, fossil fuels (like coal, oil) have a higher energy density per unit mass/volume compared to most biomass sources (though it can vary depending on the biomass type and conversion process), so this is a fiction.
• "Biofuels can only come from dead matter": Biofuels can come from living plant matter (e.g., sugarcane for ethanol production while the sugarcane is still alive in a sense of being in the growing cycle), so this is a fiction.
• "Can only be used in a limited area of the world": Biomass can be used in many parts of the world where there is plant growth (which is most regions), so this is a fiction.

Answer:

• Fact:
• "Fossil fuels are currently used to harvest many crops and process plant waste before it can be used as fuel"
• "Allows people to repurpose waste for energy production"
• "Releases greenhouses gases that increase air pollution and contribute to global climate change"
• Fiction:
• "Is a renewable energy resource" (Note: This is actually a fact, likely a mis - categorization in the original)
• "Can only be used in large scale power plants for fuel"
• "Generates more energy than fossil fuels"
• "Biofuels can only come from dead matter"
• "Can only be used in a limited area of the world"
