The cheapest reliability lever on a climate-changed grid is not a new turbine. It is the latitude and longitude of the next wind farm, solar array, and battery.
For decades, developers have sited renewables and storage against the climate of the past: wind corridors measured in 1980, solar yields averaged over thirty years, transmission drawn across maps that no longer describe the weather. Howland's Nature Energy framework rewrites the workflow. It runs fine-scale meteorology against hour-by-hour infrastructure simulations for tomorrow's climate and asks where projects should actually go.
Applied to decarbonized systems in New England and Texas, the result is a fivefold swing. Systems designed for historic conditions could see energy shortfalls rise by that much by midcentury, the paper's model metric for reliability stress, not a forecast of real outage minutes, scoped by the authors to this study. Re-site those projects for the climate the regions are actually inheriting, and the team reports most of the gap closes at no or very little additional cost.
AI demand is locking in 2026–2030 siting decisions that will define the grid through 2050. Planners who draw yesterday's weather map will pay for the same capacity twice. Planners who draw tomorrow's will buy the same resilience for a rounding error.
The grid's reliability is a siting decision. It always was.
