A cloud region has a solar-heavy grid where the cleanest carbon window is 10:00 to 16:00 (midday solar), but compute pricing is highest during those same hours due to peak business demand. Overnight pricing is 60% cheaper but carbon intensity is 3x higher. Which statement best describes this situation?

Question

Accepted Answer

Carbon and cost optimisation point in opposite directions in this grid; the scheduling system must accept higher cost for lower carbon, higher carbon for lower cost, or find a compromise window

Answer

The overnight window is always preferable because cost savings can be used to purchase carbon offsets

Answer

This conflict does not arise in practice because low-carbon periods always coincide with low-cost periods

Answer

The organisation should always choose the midday window because carbon savings should override cost considerations
