Question 6

A key strategy for mitigating the intermittency of renewable energy sources on a large scale is to geographically diversify their deployment. What is the primary benefit of this approach?

Accepted Answer

It ensures that a drop in generation from one area (e.g., due to cloud cover) can be offset by higher generation in another area.

Answer

It reduces the capital cost of individual renewable energy projects.

Answer

It eliminates the need for any form of energy storage.

Answer

It simplifies the process of obtaining regulatory approvals.
