Tensions are rising over a large proposed dam that would flood six rural villages—and their microhydro systems—to provide power and water to cities.

Nestled within the rain forest of Malaysian Borneo, a handful of villages are so remote they don't even have roads. They do, however, have electricity.

The villages draw on the nearby Papar River's current to generate enough power to run lights, refrigerators, and phone-chargers for up to 50 households. The systems, dubbed "microhydro," are small-scale versions of the same hydroelectric dams that help power large cities.
