Frogs. Bees. Finicky software. There are a lot of things that can cause an electric vehicle charging station to break. We need to replace fossil-fuel powered vehicles with EVs as soon as possible—but if the stations don’t work, it will slow the adoption of EVs.

In Los Angeles, two black women have started training a small army of technicians to fix broken charging stations, and they’re taking their model around the country. They couldn’t have started at a better time: The U.S. is investing hundreds of billions of dollars in EV charging infrastructure.

But as they’re fixing these stations, they’re asking an equity question: who benefits from this rapidly growing industry? Will cleantech remain a field dominated by white men?

As part of their business model, they’re training a diverse, inclusive workforce to be a part of the industry. In effect, they’re solving a carbon emissions problem and an equity problem at the same time.
