Researchers studied the impact of providing information about fuel costs on consumers’ car purchases. Providing information about fuel costs had no effect on the fuel efficiency of the vehicles consumers chose to buy.

Researchers introduced two programs during peak consumption hours—text messages encouraging energy conservation for the benefit of society, or price increases—to evaluate the impact of social motivation and dynamic pricing on energy conservation. Both programs led to reductions in electricity use...
