Question

select all the correct answers.
which three statements provide reasons that scientists are considering renewable sources of energy?
□ most renewable resources are clean and nonpolluting.
□ renewable resources can be replenished.
□ renewable resources are conventional resources.
□ most renewable resources are easily available in nature.
□ all renewable resources are cost effective.

Explanation:

1. Analyze each option:

• "Most renewable resources are clean and nonpolluting": Renewable energy sources like solar, wind, etc., produce little to no pollution, so this is a valid reason.
• "Renewable resources can be replenished": By definition, renewable resources (e.g., sunlight, wind, biomass) are naturally replenished, making them sustainable long - term, so this is a reason.
• "Renewable resources are conventional resources": Conventional resources are non - renewable (like fossil fuels), so this is incorrect.
• "Most renewable resources are easily available in nature": Resources like sunlight, wind, and water are abundant in nature, which is a reason to consider them.
• "All renewable resources are cost effective": Not all renewable resources are cost - effective (e.g., some bioenergy production can be costly), so this is incorrect.

Answer:

A. Most renewable resources are clean and nonpolluting.
B. Renewable resources can be replenished.
D. Most renewable resources are easily available in nature.
