Erika Beras from the Planet Money team interviews the architect of the plan that made this possible.

How can Uruguay use nontraditional renewables without battery storage?

By balancing complementary resources in particular locations and at particular times of day, Uruguay has been able to incorporate large amounts of nontraditional renewables without any battery storage.

What was the energy grid like in Uruguay?

Uruguay's energy grid was powered almost exclusively by domestically created, renewable energy, and, adjusted for inflation, consumer prices had gone down. Today, there are more than 700 wind turbines installed across Uruguay's countryside. "It was absolutely a complete transformation," says Méndez Galain.
