To gauge every state’s sustainability, we take into account NOAA’s Climate Extremes Index, which measures regional knowledge on storms, precipitation, warmth and drought. We take into account every state’s danger of main disasters together with flooding, winds, wildfires and smoke, utilizing knowledge compiled for CNBC by the nonprofit First Street Foundation. And, new in 2025, property knowledge agency Cotality scored every state’s resilience to present and future disasters for CNBC, utilizing its propriety data on thousands and thousands of properties.

We additionally measure renewable power in every state utilizing U.S. Department of Energy knowledge. President Trump’s signature tax and spending invoice slashes clean energy funding whilst demand for electrical energy soars. That might give an edge to states that have already got that infrastructure in place.

These ten states are finest outfitted to take no matter punches Mom Nature throws at them.

The Mount Rushmore State is a frontrunner in renewable power. Roughly two-thirds of the state’s energy final 12 months got here from renewable sources, in response to the Vitality Division. That’s the third highest proportion within the nation. Traditionally, South Dakota primarily relied on wind power for a lot of that energy, with 29 wind farms throughout the state. However now, the state’s give attention to renewables is increasing. In January, the South Dakota Wind Vitality Affiliation modified its identify to the South Dakota Renewable Energy Association, advocating for solar energy, hydrogen, biofuels and power storage along with wind.

Democratic Gov. Katie Hobbs’ Workplace of Resiliency developed the state’s first Extreme Heat Preparedness Plan. It focuses on creating secure and inexpensive housing, bettering emergency response, and increasing the state’s community of cooling facilities. The workplace can also be working to develop extra renewable power — a specific problem in a state with such huge and rising electrical energy demand.

Renewable power is in The Hawkeye State’s DNA, however not essentially in the way in which you may suppose. Iowa is the nation’s main producer of ethanol, and the most important booster of the corn-based gasoline additive. However the state actually blows the others away in harnessing the wind. The Vitality Division says Iowa is the second largest generator of electrical energy from wind, after Texas. The state’s Economic Development Authority says that has attracted massive power customers together with Google, Fb and Microsoft. Iowa has additionally seen the unfavorable results of wind, together with the 2020 derecho that left hundreds with out energy. Statistically, the state nonetheless has little danger of a serious catastrophe. Maybe in consequence, it has finished comparatively little to guard itself from local weather dangers.

The Silver State units the gold customary for renewable power use, serving to to make Nevada America’s most sustainable state in 2025. Nevada’s Public Utilities Fee first set a standard for renewables within the state’s power proposal again in 2019, and the state has already surpassed its objective of fifty% renewables by 2030. The state has plentiful sources of renewable energy together with wind, photo voltaic, geothermal. And, after all, it’s wealthy in hydroelectric energy, practically all of it coming from the Hoover Dam, which sits on the Nevada-Arizona border.
