The 28 pages that link to Combined heat and power, each with the reason it gives.
Fuel cellRelated: Stationary fuel cells can make use of both electrical output and reaction heat.
Anaerobic digestionRelated: Engines can use digester biogas to supply power and recoverable heat.
BiofuelRelated: Biomass and biogas can supply both outputs in one installation.
MicrogridRelated: Capturing generator waste heat can improve a microgrid's overall fuel efficiency.
BoilerRelated: Some boiler-based plants supply both turbine power and recoverable heat.
BiogasRelated: Biogas engines can generate electricity while recovering engine heat.
ExergyRelated: Exergy distinguishes valuable electrical output from lower-grade heat output.
Waste heatBroader topic: It makes rejected heat a planned output alongside electricity.
CogenerationRelated: This is the standard engineering name for cogeneration systems.
MicrogenerationNarrower topic: Micro combined heat and power is its small-scale form.
Energy engineeringBroader topic: Using both outputs can reduce wasted energy at suitable sites.
Energy sourceRelated: Using both outputs can make fuel-based generation more efficient.
