Advantages of nuclear power over thermal power power stations:

• Lower energy density, higher greenhouse gas emissions, and larger land footprint.
• Lower energy density, higher greenhouse gas emissions, and similar land footprint.
• Higher energy density, higher greenhouse gas emissions, and larger land footprint.
• Higher energy density, lower greenhouse gas emissions, and smaller land footprint.

Why are MEDC's more likely to increase their nuclear power generation than LEDC's?

• LEDC's have equal financial resources, technological capabilities, electricity demand, and environmental regulations as MEDC's.
• LEDC's have less financial resources, technological capabilities, lower electricity demand, and looser environmental regulations.
• MEDC's have more financial resources, technological capabilities, higher electricity demand, and stricter environmental regulations.
• LEDC's have more financial resources, technological capabilities, higher electricity demand, and stricter environmental regulations.
