Distributed generators can be used meet a variety of environmental goals, from reducing methane emissions at hog farms and landfills to environmental education. Load-reduction measures and renewable energy systems are sometimes incorporated to reduce overall air pollution — especially important when the primary power source is a diesel generator.
Some examples:
- Hog farm biodigester fuels 75-kW engine-generator and 30 kW microturbine — Colorado Pork, LLC, Lamar, Colorado.
- Dairy farm biodigester produces 70 kW of power from 20 tons of manure per day — Portland General Electric biogas facility, Cal-Gon dairy farm, Salem, Oregon.
- 6.6-MW landfill methane plant — Riverview Land Preserve, Riverview, Michigan.
- Passive solar heating, natural ventilation, daylighting, efficient lighting, and building controls cut demand by 10 kW for national park buildings — Zion Visitor and Transportation Center, Springdale, Utah.
- Mountain building relies on passive solar heating — Rocky Mountain Institute, Snowmass, Colorado.
- 660-kW wind installation with diesel generator powers remote community — Kotzebue Electric Association, Kotzebue, Alaska.
