Fusion vs solar + storage for firm power.
Solar and batteries are the cheapest new energy — but they're variable and duration-limited. For 24/7 firm load like AI data centers, fusion is designed to be the always-on complement.
Cheap and variable vs firm and dense.
- Lowest-cost new generation; scales fast
- Weather- and season-dependent; batteries cover hours, not weeks
- Large land and transmission footprint for firm output
- Ideal for daytime and short-duration balancing
- Firm, dispatchable, weather-independent — runs day and night
- Compact, sited near load — eases transmission
- Carbon-free and low-neutron
- Built for 24/7 baseload: AI, industry, defense
This isn't either/or. A clean grid needs both — renewables for cheap energy, fusion for firm power.
