All Flashcards
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.
What is the effect of burning fossil fuels?
Increased greenhouse gas emissions, leading to climate change and air pollution.
What is the effect of using renewable energy sources?
Reduced greenhouse gas emissions and decreased reliance on finite resources.
What are the consequences of habitat destruction for energy extraction?
Loss of biodiversity, disruption of ecosystems, and potential for soil erosion and water pollution.
How does deforestation affect climate change?
Reduces carbon sequestration, leading to increased atmospheric carbon dioxide and global warming.
What is the effect of increased reliance on renewable energy on job creation?
Growth of new job opportunities in renewable energy sectors like solar, wind, and hydroelectric power.
What is the impact of reduced reliance on fossil fuel imports?
Increased energy independence and reduced vulnerability to price fluctuations and geopolitical instability.
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.
What are fossil fuels?
Combustible geologic deposits of organic matter that can be used as a fuel source.
Define biomass.
Organic matter that can be burned as fuel or converted into other forms of energy.
