Question

categorization 10 points
determine if each statement is fact or fiction for hydropower energy.
fact
is a renewable resource
migrating species are not able to pass the water barrier without human modifications
dams are often long - standing energy efficient structures once constructed
can be impacted by the weather but gravity is the driving factor for energy generation
fiction
produces air pollution
does not impact local ecosystems or wildlife
hydroelectric energy use increases fossil fuel demands
limited amount of resource available for use

Explanation:

• Is a renewable resource: Hydro - power is a renewable resource as water is a continuously replenished natural resource.
• Can be impacted by the weather but gravity is the driving factor for energy generation: Hydro - power generation depends on water flow. Weather affects water availability (e.g., rainfall for rivers), and gravity drives the water down through turbines.
• Dams are often long - standing energy efficient structures once constructed: Dams are built to last and, once operational, can generate electricity efficiently over long periods.
• Migrating species are not able to pass the water barrier without human modifications: Dams act as barriers to fish and other migrating species, and human - made structures like fish ladders are often needed for them to pass.

• Produces air pollution: Hydro - power does not produce air pollution during electricity generation (unlike fossil fuels).
• Does not impact local ecosystems or wildlife: Hydro - power can impact local ecosystems by flooding areas, changing water flow, and affecting habitats.
• Hydroelectric energy use increases fossil fuel demands: Hydro - power is a substitute for fossil fuels, reducing their demand.
• Limited amount of resource available for use: There is a large potential for hydro - power globally (though site - specific), and it is not as limited as some non - renewable resources.

Answer:

• Fact: "Is a renewable resource", "Can be impacted by the weather but gravity is the driving factor for energy generation", "Dams are often long - standing energy efficient structures once constructed", "Migrating species are not able to pass the water barrier without human modifications"
• Fiction: "Produces air pollution", "Does not impact local ecosystems or wildlife", "Hydroelectric energy use increases fossil fuel demands", "Limited amount of resource available for use"
