[Energy in buildings](https://www.materialinsights.org/energy/e_buildings/) (energy) and [Lighting and displays](https://www.materialinsights.org/energy/e_lighting/) (energy): 2 relationships.

## How they are linked

### 1. Energy flow

*Physical flow · 88% of flow · Lighting and displays → Energy in buildings*

Lamps and screens light homes and workplaces.

- **88%** of Lighting and displays's energy goes this way

### 2. Price link: demand driver

*Cost and price · Strong · Both ways*

Most lighting sits in homes and offices, and the electricity it saves is the main reason to switch to LEDs. Yearly moves correlate at 0.63 with the electricity proxy, mostly a shared US price cycle rather than a direct cost link.

- **0.09** monthly change correlation
- **0.63** 12-month change correlation
- **1.04** fitted elasticity
