Too Hot not to Handle
Every region in the U.S. is experiencing year after year of record-breaking heat. More households now require home cooling solutions to maintain safe and liveable indoor temperatures. Over the last two decades, U.S. consumers and the private sector have leaned heavily into purchasing and marketing conventional air conditioning (AC) systems, such as central air conditioning, window units and portable ACs, to cool down overheating homes.
While AC can offer immediate relief, the rapid scaling of AC has created dangerous vulnerabilities: rising energy bills are straining people’s wallets and increasing utility debt, while surging electricity demand increases reliance on high-polluting power infrastructure and mounts pressure on an aging power grid increasingly prone to blackouts. There is also an increasing risk of elevated demand for electricity during a heat wave, overloading the grid and triggering prolonged blackouts, causing whole regions to lose their sole cooling strategy. This disruption could escalate into a public health emergency as homes and people overheat, leading to hundreds of deaths.
What Americans need to be prepared for more extreme temperatures is a resilient cooling strategy. Resilient cooling is an approach that works across three interdependent systems — buildings, communities, and the electric grid — to affordably maintain safe indoor temperatures during extreme heat events and reduce power outage risks.
This toolkit introduces a set of Policy Principles for Resilient Cooling and outlines a set of actionable policy options and levers for state and local governments to foster broader access to resilient cooling technologies and strategies.
This toolkit introduces a set of Policy Principles for Resilient Cooling and outlines a set of actionable policy options and levers for state and local governments to foster broader access to resilient cooling technologies and strategies. For example, states are the primary regulators of public utility commissions, architects of energy and building codes, and distributors of federal and state taxpayer dollars. Local governments are responsible for implementing building standards and zoning codes, enforcing housing and health codes, and operating public housing and retrofit programs that directly shape access to cooling.
The Policy Principles for Resilient Cooling for a robust resilient cooling strategy are:
- Expand Cooling Access and Affordability. Ensuring that everyone can affordably access cooling will reduce the population-wide risk of heat-related illness and death in communities and the resulting strain on healthcare systems. Targeted financial support tools — such as subsidies, rebates, and incentives — can reduce both upfront and ongoing costs of cooling technologies, thereby lowering barriers and enabling broader adoption.
- Incorporate Public Health Outcomes as a Driver of Resilience. Indoor heat exposure and heat-driven factors that reduce indoor air quality — such as pollutant accumulation and mold-promoting humidity — are health risks. Policymakers should embed heat-related health risks into building codes, energy standards, and guidelines for energy system planning, including establishing minimum indoor temperature and air quality requirements, integrating health considerations into energy system planning standards, and investing in multi-solving community system interventions like green infrastructure.
- Advance Sustainability Across the Cooling Lifecycle. Rising demand for air conditioning is intensifying the problem it aims to solve by increasing electricity consumption, prolonging reliance on high-polluting power plants, and leaking refrigerants that release powerful greenhouse gases. Policymakers can adopt codes and standards that reduce reliance on high-emission energy sources and promote low-global warming potential (GWP) refrigerants and passive cooling strategies.
- Promote Solutions for Grid Resilience. The U.S. electric grid is struggling to keep up with rising demand for electricity, creating potential risks to communities’ cooling systems. Policymakers can proactively identify potential vulnerabilities in energy systems’ ability to sustain safe indoor temperatures. Demand-side management strategies, distributed energy resources, and grid-enhancing technologies can prepare the electric grid for increased energy demand and ensure its reliability during extreme heat events.
- Build a Skilled Workforce for Resilient Cooling. Resilient cooling provides an opportunity to create pathways to good-paying jobs, reduce critical workforce gaps, and bolster the broader economy. Investing in a workforce that can design, install, and maintain resilient cooling systems can strengthen local economies, ensure preparedness for all kinds of risks to the system, and bolster American innovation.
By adopting a resilient cooling strategy, state and local policymakers can address today’s overlapping energy, health, and affordability crises, advance American-made innovation, and ensure their communities are prepared for the hotter decades ahead.
The Federation of American Scientists supports the Wildfire Emissions Prevention Act of 2026 (WEPA). The Act would amend Section 319(b) of the Clean Air Act so that it addresses prescribed burns as a standalone activity. If passed, this bill would support wildfire resilience by reducing administrative barriers to getting needed prescribed burns on the ground. […]
The NCARS Act would amend the National Security Act of 1947 to establish a durable, coordinated federal approach to national resilience.
Nearly 150 organizations and government officials have endorsed the call to action and solutions for extreme heat, now public at HeatAgenda.US Washington, D.C. – July 7, 2026 – As millions of Americans continue to struggle to stay cool following one of the hottest Independence Day holidays on record, the Federation of American Scientists (FAS), one […]
Addressing rising heat will take all of us. Together, we can create heat-safe homes, workplaces, schools, childcare facilities, and communities – the backbone of a heat-ready nation.
