Key Findings
- Minimal Electricity Cost Impact: Monthly increase of $1-10 in most scenarios
- LLM Inference is Bursty: GPU consumes high power only during brief inference periods, otherwise idle
- Apple Silicon is Most Power-Efficient: M-series chips consume far less power than x86 + dedicated GPU solutions

Cost-Saving Tips
- Prioritize Utilizing Existing Devices: Any computer with 16GB RAM can run OpenClaw
- Choose Low-Power Devices: Mac Mini M4 or Intel N100 are the best choices
- Use Cloudflare Tunnel: Free secure external access, no need for static IP
- Consider UPS: $50-150 investment can prevent data loss from sudden power outages
- No Need for Dedicated Network: Regular home broadband is sufficient
Conclusion
Home network and electricity costs are the lowest cost items in OpenClaw's local deployment. Utilizing existing devices results in an additional monthly expense of only $2-5 (electricity). Even purchasing a dedicated device (Mac Mini M4) amortizes to a monthly cost of around $20. This makes OpenClaw's local deployment highly attractive economically, far cheaper than equivalent cloud VPS solutions.
