Renewable Resources
What is something that can be replaced or reused naturally?
renewable energy
Name one fossil fuel.
Coal, oil, or natural gas.
What device turns sunlight into electricity?
A solar panel.
What’s one good thing about solar energy?
it doesn't cause pollution
What kind of energy do most homes use today?
A mix, but mostly from fossil fuels.
Name two types of renewable energy that come from the Earth, not the sky
geothermal and biomass
Why are fossil fuels called “non-renewable”?
Because they take so long to form that we can't replace them quickly.
What is a dam used for in hydroelectric power?
To control water flow and generate electricity.
What’s one problem with wind energy?
only works when the wind is blowing
What kind of renewable energy could be best in a windy, flat state like Kansas?
Wind energy.
What does a wind turbine do?
It turns wind energy into electricity.
How long does it take for fossil fuels to form? (generally)
millions of years
What kind of energy is used when you burn wood for heat?
Biomass
Why do some people not want wind farms near their homes?
They think the turbines are too noisy or ugly.
Name a place where geothermal energy is commonly used.
Iceland or parts of California.
Which renewable energy comes from plant and animal waste?
Biomass
What happens when we burn fossil fuels?
It releases pollution and carbon dioxide into the air.
How does geothermal energy create electricity?
Heat from underground warms water into steam, which spins turbines.
What is a benefit of using geothermal energy?
It’s always available, no matter the weather.
Why do schools and businesses install solar panels?
To save money and use clean energy.
Why might a community choose to use a combination of solar, wind, and biomass energy instead of relying on just one renewable source?
Because using a mix of renewable sources can provide more reliable energy year-round—if one source isn’t available (like sun on cloudy days), others (like wind or biomass) can still produce energy.
What is one way mining for fossil fuels affects the environment?
It can destroy habitats and pollute water.
What happens inside a wind turbine when the blades turn?
The motion powers a generator that makes electricity.
What is a downside of building dams for hydroelectric power?
It can change river ecosystems and affect fish habitats.
What is one reason governments support renewable energy?
To reduce pollution and fight climate change.
