More than a decade ago—when wind and solar power were far more expensive than they are today—Uruguay, long plagued by droughts and energy shortages, transitioned its entire economy such that 98% of its electricity now comes from renewable sources. They did it in just two years, and used the savings to slash the country's poverty rate from 40% into the single digits.

Natasha Hakimi Zapata covers Uruguay's transformation in her book, Another World Is Possible: Lessons for America from Around the Globe. Hakimi Zapata shares how activists and policymakers can learn from Uruguay's transformation and why progressive movements should confidently articulate the economic benefits of renewable energy.
