[Energy-intensive industry](https://www.materialinsights.org/energy/e_heavy_industry/) (energy) and [Waste-heat power (steam Rankine)](https://www.materialinsights.org/energy/e_whr_rankine/) (energy): 3 relationships.

## How they are linked

### 1. Energy flow

*Physical flow · Direct · Energy-intensive industry → Waste-heat power (steam Rankine)*

Cement and steel plants raise steam from waste heat.

### 2. Energy flow

*Physical flow · 95% of flow · Waste-heat power (steam Rankine) → Energy-intensive industry*

Recovered power supplies plant demand.

- **95%** of Waste-heat power (steam Rankine)'s energy goes this way

### 3. Price link: power price

*Cost and price · Weak · Both ways*

Waste-heat power replaces electricity a plant would buy, so high industrial tariffs shorten payback. The equipment index shows no link with industrial power, at -0.02 monthly, as turbine prices follow the makers' order books.

- **-0.02** monthly change correlation
- **-0.01** 12-month change correlation
- **0.55** fitted elasticity
