Energy Sustainability of Renewable-Non-renewable Energy Sources

Which of the following best describes why solar energy is considered renewable?

• It produces no greenhouse gas emissions

• The sun's energy is inexhaustible within human time scales

• Solar panels require minimal maintenance

• It is available only in certain regions

Fossil fuels are considered non-renewable primarily because:

• They take millions of years to form and cannot replenish at the rate they are consumed

• They are always expensive to extract

• They do not contribute to air pollution

• They can be easily replaced with biofuels

Which of the following is the greatest environmental drawback of fossil fuel use?

• High energy output

• Carbon dioxide emissions contributing to climate change

• Easy accessibility

• Stable energy production

Which of the following is a major limitation of wind energy?

• It is non-renewable

• It is always reliable

• It can be inconsistent due to wind variability

• It produces significant air pollution

5. A critical challenge of transitioning to 100% renewable energy globally is:

• High initial costs

• Lack of public awareness

• Limited availability of technology

• Political resistance

What is one major reason geothermal energy is not widely used?

• It is not a reliable source of energy

• It requires specific geological conditions that are not present everywhere

• It contributes to global warming more than coal

• It cannot be used for electricity generation

Compared to fossil fuels, nuclear energy:

• Produces less carbon dioxide but creates radioactive waste

• Requires less regulation and safety measures

• Is less efficient in producing electricity

• Is more widely used than coal

Why is hydropower sometimes considered unsustainable despite being renewable?

• It requires the burning of fossil fuels

• It cannot be used to generate electricity

• It can disrupt aquatic ecosystems and lead to habitat destruction

• It does not generate significant energy output

Why is the transition to electric vehicles (EVs) considered an important step toward sustainability?

• EVs eliminate all carbon emissions

• EVs rely on fossil fuels to generate power

• EVs reduce dependence on non-renewable petroleum-based fuels

• EVs require more energy to produce than gasoline-powered cars

Which of the following is a major reason why biomass is considered a renewable energy source?

• It does not release carbon dioxide when burned

• It can be replenished in a relatively short amount of time

• It is derived from fossilized plant matter
