Energy Basics
The ability to do work or cause change.
What is a renewable resource?
A resource that can be replenished naturally over time.
What is one advantage of renewable energy?
It doesn’t run out, it’s better for the environment, etc.
Name one factor that governments consider when deciding on energy use.
Cost, availability, environmental impact, etc.
How do windmills generate electricity?
Wind turns the blades, which spin a generator to produce electricity.
Give an example of how we use energy in our daily lives.
Turning on lights, cooking, driving, etc.
What is a nonrenewable resource?
A resource that cannot be replenished quickly and will eventually run out.
What is one disadvantage of renewable energy?
Can be expensive, depends on weather, etc.
How does energy production affect the environment?
It can lead to pollution, habitat destruction, etc.
What are two advantages of using wind energy?
(It’s renewable and doesn’t produce air pollution.
What is direct-use energy?
Energy that is used in its natural form, like sunlight or wind.
Give an example of a renewable resource.
Solar, wind, hydro, etc
What is one advantage of nonrenewable energy?
Often more efficient and cost-effective in the short term.
Why do energy companies need to manage resources responsibly?
To ensure long-term availability and reduce environmental damage.
Why are windmills usually built in open areas or on hills?
Wind speeds are higher and more consistent in these locations.
What is processed-use energy?
Energy that has been changed into another form, like gasoline from crude oil.
Give an example of a nonrenewable resource
Coal, oil, natural gas, etc.
What is one disadvantage of nonrenewable energy?
It can cause pollution and will eventually run out.
What is one way governments encourage the use of renewable energy?
Subsidies, tax breaks, laws, etc
What is one challenge of using wind energy?
Wind isn’t always available, and turbines can be expensive to install.
Name two examples of direct-use and processed-use energy.
Direct: sunlight, wind. Processed: gasoline, electricity from coal.
What are tailings, and why are they important in energy production?
Waste materials left over after extracting valuable minerals or fuels, often requiring careful management to reduce environmental harm
Why is reclamation important in energy resource management?
It helps restore land after mining or drilling to reduce environmental impact.
How do tailings affect the environment, and what can be done to reduce their impact?
They can pollute water and soil; proper disposal and treatment can help minimize harm.
What is the term for changing the angle on the blade of a windmill?
Pitch
