Episode notes
Local Subsidies Can Raise Utility Costs
- Jaeden describes seeing rising energy costs in Arizona where subsidized projects increased local utility prices.
- He connects subsidies for large facilities to higher community energy bills and infrastructure strain.
On-Site Power Changes Data Center Impact
- XAI will build a solar farm beside Colossus to reduce external grid strain from AI compute demand.
- On-site generation changes how data centers affect local utilities and could become an industry blueprint.
Solar Won't Fully Power Colossus
- The planned solar farm will produce about 30 megawatts, roughly 10% of Colossus's estimated demand.
- Small on-site renewables help but won't fully replace large-scale turbine or grid power needs.
