NRCan energy efficiency regulation example.

• A. Only consumer demand.
• B. Export quotas.
• C. NRCan energy efficiency standards, ENERGY STAR program.
• D. Subsidies for all appliances.

Answer: (C)

Regulatory approaches that set minimum efficiency levels and provide standardized labeling are how governments promote energy efficiency. NRCan’s energy efficiency standards establish required performance for appliances, while the ENERGY STAR program offers a trusted label for products that exceed those standards. This combination creates a clear baseline for manufacturers and an easy way for consumers to identify efficient options, driving market change and reducing energy use. The other options don’t fit because they rely on market demand alone, trade controls, or broad subsidies rather than concrete standards and a labeling program that guide choices and spur improvements.
