Question

what is the biggest barrier to the use of renewable energy in the united states?
limited renewable resources
citizen opposition to negative environmental impact
reliability and consistency
limited transmission capacity to deliver the energy to the consumer

Explanation:

To determine the biggest barrier to renewable energy use in the US:

• "Limited renewable resources" is incorrect as the US has abundant renewable resources (e.g., solar, wind potential).
• "Citizen opposition to negative environmental impact" is wrong because renewable energy generally has positive environmental impacts, and opposition is not a major barrier.
• "Reliability and consistency" (intermittency) is a challenge but not the biggest barrier overall.
• "Limited transmission capacity" is a major barrier. The existing grid infrastructure often lacks the capacity to transmit renewable energy from production sites (e.g., rural wind/solar farms) to urban consumers, hindering widespread adoption.

Answer:

D. Limited transmission capacity to deliver the energy to the consumer
