The mechanism: Building codes are the least glamorous, most reliable lever in policy investing. States don't have to agree on climate policy to converge on the same electrical spec — they just have to update their energy code, and California already has. Title 24's 2025 code, effective January 1, 2026, mandates electric-ready pre-wiring for heat pump water heaters and electric cooking in new multifamily and commercial-kitchen construction, plus expanded EV-charging infrastructure requirements for assigned and common parking. Colorado's Electric-Ready Code goes statewide by July 2026. The 2026 National Electrical Code adds new provisions for EV circuits and energy management systems that let one panel serve more loads. None of this requires a coal plant to close or a wind farm to get built — it just requires every new panel, breaker, and piece of switchgear sold in these jurisdictions to handle more amperage, more circuits, and more smart-load management than it did five years ago. That's a demand floor set by code inspectors, not by the power mix.
