| Many of the benefits of cogeneration stem from the relatively high efficiency of cogeneration systems. |
| |
| The illustration below shows the efficiency advantage of cogeneration compared with separate heat and power from on-site boilers and conventional Grid power generation. |
| |
| When considering both thermal and electrical processes together, cogeneration typically requires only 65% the primary energy that separate heat and power systems require. |
| |
| This reduced primary fuel consumption is key to the environmental benefits of cogeneration. Burning less fuel more efficiently results in fewer emissions for the same level of output, and a significantly reduced carbon footprint. |
