Why are fossil fuels considered nonrenewable?
They take millions of years to form, far exceeding a human lifespan.
What is the primary environmental concern with nonrenewable energy?
Greenhouse gas emissions and pollution contribute to climate change and environmental degradation.
Why is sustainability important when considering energy sources?
Ensures long-term availability of resources and minimizes environmental impact for future generations.
What role does energy play in climate change?
The burning of fossil fuels releases greenhouse gases, which trap heat and contribute to global warming.
How can renewable energy mitigate climate change?
Renewable sources produce little to no greenhouse gas emissions, reducing our carbon footprint.
Why is transitioning to renewable energy an economic issue?
It creates new jobs, reduces reliance on fossil fuel imports, and can lead to long-term cost savings.
Define nonrenewable energy.
Energy sources that exist in limited quantities and cannot be replenished within a human lifespan.
Define renewable energy.
Energy sources that can be replenished at or near the rate of consumption.
Define fossil fuels.
Nonrenewable energy sources formed from the remains of ancient plants and animals.
What is biomass?
Organic matter used as a renewable energy source, such as wood or crops.
Define hydroelectric power.
Electricity generated from the energy of moving water.
Why is sustainability important in energy use?
Ensures long-term availability of resources and minimizes environmental impacts.
What is the role of energy in climate change?
Burning fossil fuels releases greenhouse gases, contributing to global warming.
Explain the concept of energy depletion.
The finite supply of nonrenewable resources means they will eventually run out.
What are greenhouse gas emissions?
Gases released into the atmosphere that trap heat and contribute to climate change.
Describe the environmental impact of habitat destruction.
Loss of biodiversity and disruption of ecosystems due to human activities.
What are the benefits of transitioning to renewable energy?
Reduced greenhouse gas emissions, decreased air pollution, and long-term resource availability.
Why is energy policy important?
Guides the development and use of energy resources to balance economic, environmental, and social goals.
Describe the difference between correlation and causation.
Correlation indicates a relationship between two variables, while causation means one variable directly causes a change in another.
What is the significance of carbon footprint?
The total amount of greenhouse gases generated by our actions.
