# Energy Efficiency

The Tier-S and Tier-H model is designed for exceptional energy efficiency.

### Key Metrics:
- **Power Usage Effectiveness (PUE)**: Can achieve PUE ratings as low as 1.1, compared to 1.5-2.0 for traditional data centers.
- **Energy Savings**: For a 1 MW IT load, this translates to **350,000–440,000 kWh** in monthly energy savings, or over **$500,000 annually**.
- **Cooling Power Reduction**: Cooling-related energy usage can be cut by nearly half.

### Compatibility with Renewables:
- The low energy requirements make the Tier-S and Tier-H model compatible with on-site renewables like solar and biomass, reducing dependency on the national grid and improving energy independence.
