Question

why are renewable energy sources important for the future? they are cheaper than all fossil fuels due to accessibility costs. they never require maintenance because of their simplicity. they can be replenished and reduce environmental impact.

Explanation:

• The first option is incorrect because renewable energy sources are not necessarily cheaper than all fossil fuels (e.g., some fossil fuels might be cheaper in certain contexts or regions).
• The second option is incorrect as renewable energy infrastructure (like solar panels, wind turbines) does require maintenance.
• The third option is correct because renewable energy sources (e.g., solar, wind, hydro) are naturally replenished and they produce less pollution and environmental degradation compared to fossil fuels, which is crucial for the future to address climate change and resource depletion.

Answer:

They can be replenished and reduce environmental impact.
