What type of renewable energy comes from plants, food waste, or animal waste?
Biomass energy
What moving resource is used to generate water energy?
Moving water (flowing or falling water)
What natural force spins wind turbines?
Wind
What is the Sun’s energy called?
Solar energy
What type of energy resource cannot be replaced quickly?
Non-renewable energy
Give one example of biomass material.
Examples: wood, plants, food scraps, animal manure (any one)
What is the name of energy made using flowing water?
Hydroelectric energy / Hydropower
What machine is used to turn wind into electricity?
Wind Turbine
What device is used to collect solar energy?
Solar panels (or solar cells)
Name one fossil fuel.
Coal, oil, or natural gas (any one)
Why is biomass considered renewable?
Because plants and organic materials can be regrown or replaced
Why are dams often built near rivers?
To control water flow and generate electricity using turbines
Why are wind turbines often built in open areas?
There is stronger, more consistent wind and fewer obstacles
Why does solar energy work best on sunny days?
Solar panels need sunlight to produce energy
What gas is released when fossil fuels are burned?
Carbon dioxide (CO₂) (accept methane if explained)
How does burning biomass produce energy?
Burning biomass releases stored chemical energy as heat, which can be used to make electricity
Name one environmental impact of building a dam.
Flooding land, harming ecosystems, blocking fish migration (any one)
What is one disadvantage of wind energy?
Wind is not constant; turbines can be noisy or affect wildlife (any one)
What is one limitation of solar energy?
It doesn’t work well at night or on cloudy days; can be expensive (any one)
How do fossil fuels contribute to climate change?
Burning fossil fuels releases greenhouse gases that trap heat in the atmosphere
Explain one way biomass energy can help reduce waste.
It reduces waste by using food scraps or plant material instead of sending them to landfills
Explain how water energy is changed into electrical energy.
Moving water spins turbines, which turn generators to produce electricity
Explain how wind speed affects electricity production.
Faster wind spins turbines more quickly, producing more electricity
Explain why solar energy is considered clean energy.
It produces energy without releasing pollution or greenhouse gases
Explain the connection between fossil fuels and greenhouse gases.
Fossil fuels release greenhouse gases when burned, which trap heat and contribute to global warming and climate change
