In India, home to 21 of the world’s 30 most-polluted cities, many air pollutants come from the millions of auto rickshaws that navigate congested streets. So Power Global created the eZee module, a subscription battery service for drivers who use cleaner electric rickshaws. Drivers receive a battery module, which they can swap when depleted for charged ones at a growing network of kiosks, for roughly $2 to $3 per day—a savings of at least 30% per day compared with diesel or petrol costs. “That’s a huge amount for someone making between $8 and $10 a day,” says Power Global founder and CEO Porter Harris.
