Coal generation makes up about a third of the United States’ power supply — a share that has been shrinking thanks to a boom in natural gas, among other factors. As the end of coal looks more and more inevitable, so does the need for “just transitions.” That is, the engineering of fair economic and environmental conditions for communities who have historically relied on fossil fuel extraction.

Around the world, as governments shift away from the coal that fueled two ages of industrial revolution, more and more mines are falling silent. If there’s an afterlife for retired coal mines, one that could put them to work for the next revolution in energy, it will have to come soon.

Tesla is only the most prominent company to bypass the conventional avenues of rebuilding to install renewable power and batteries. Other companies and nonprofits have been marshalling resources to fill the void left by federal relief efforts. German renewable energy outfit Sonnen has pledged to build microgrids in priority areas, working with local partner Pura Energia to install donated batteries to power first aid and community centers. Another group, Resilient Power Puerto Rico, is distributing solar generators to remote communities, where they can serve as hubs for immediate necessities like charging phones and filtering water.

How to collect that solar energy, predict it, get it to the right places at the right time, save it up for a rainy day — those are the kind of challenges our massive, spread-out, and unevenly populated country faces as we make the switch to clean energy. And it all comes down to a lesson that the Evslins learned the hard way: It’s not about getting off the grid. It’s about building a better one.
