[Combined heat and power](https://www.materialinsights.org/energy/e_chp/) (energy) and [Energy in buildings](https://www.materialinsights.org/energy/e_buildings/) (energy): 3 relationships.

## How they are linked

### 1. Energy flow

*Physical flow · Direct · Energy in buildings → Combined heat and power*

Micro-CHP units heat and power homes.

### 2. Energy flow

*Physical flow · Direct · Combined heat and power → Energy in buildings*

CHP heat warms buildings.

### 3. Price link: power value

*Cost and price · Weak · Both ways*

CHP is worth more where grid electricity is dear, since each unit made on site is a unit not bought. The equipment proxy shows no link with the electricity price, at -0.04 monthly, as tariffs change slowly and turbines are priced on orders.

- **-0.04** monthly change correlation
- **0.27** 12-month change correlation
- **0.74** fitted elasticity
