Run-of-River
A type of hydroelectric facility that generates power from the natural flow and elevation drop of a river, without creating a significant reservoir. Output varies with river conditions.
Why It Matters
Run-of-river projects have lower environmental impact than dammed reservoirs because they don't flood valleys. However, their output varies with natural water flow and they offer less control over generation timing.

Hydroelectric Dam
A structure that impounds water in a reservoir, releasing it through turbines to generate electricity. The energy comes from the gravitational potential of water stored at elevation.
Capacity Factor
The ratio of actual energy produced by a system to its maximum potential output. Solar typically has a 15-25% capacity factor.
