A recent study on residential heat and energy burdens in Miami highlights critical challenges in urban heat resilience. It reveals how rising temperatures disproportionately impact low-income households, increasing electricity costs and exposing residents to dangerous indoor heat levels. Indian cities, which face similar extreme heat risks, can draw valuable lessons urgently from this research to improve their heat mitigation strategies and energy policies for the summer of 2025.

1. Intersectionality of Heat and Energy Burdens

The study in Miami highlights two key issues:

• Heat burden: Residents, especially in low-income neighbourhoods, experience higher indoor temperatures due to poor housing conditions and lack of access to cooling solutions.
• Energy burden: Rising temperatures increase electricity demand, making cooling expensive for vulnerable populations. Even a small fan runs all day and night. This leads to a situation where many households either overpay for cooling or endure unsafe indoor temperatures to save money.

Indian cities, particularly in states like Rajasthan, Gujarat, Uttar Pradesh, Maharashtra, and Delhi, but also in Assam and Tamil Nadu face similar challenges, making it crucial to address both heat and energy burdens in urban planning.

2. Housing, Heat, and Resilience

The study finds that poorly designed homes in Miami trap heat, worsening indoor temperatures. Indian cities can learn from this by:

• Retrofitting informal settlements with heat-resistant materials to improve living conditions, matched with trees and plants in all open areas.
• Promoting cool roofs and reflective paints to reduce indoor temperatures, in addition to planting trees in the compound around the home.
• Encouraging energy-efficient housing with proper ventilation and insulation.

By implementing these solutions, Indian cities can start to create affordable and climate-resilient housing.

3. Ensuring Affordable and Sustainable Cooling

A major concern in Miami’s study is the rising cost of air conditioning, which makes cooling unaffordable for low-income families. Indian cities, where air conditioning ownership remains low, can take proactive measures by:

• Providing subsidies for sustainable cooling solutions that are nature-based in economically weaker communities.
• Encouraging passive cooling techniques like shaded windows, rooftop gardens, tree-planted streets, and cross-ventilation to reduce dependency on air conditioning.
• Expanding access to energy-efficient cooling technologies such as solar-powered fans and evaporative coolers, in addition to landscaping with trees and vegetation on available surfaces.

Affordable and sustainable cooling strategies can prevent extreme indoor heat exposure while keeping electricity costs manageable. The aim should be to reduce dependence on electricity for cooling.

4. Strengthening Energy Policies and Infrastructure

The Miami study emphasises the need for better energy policies to support vulnerable communities. Indian cities can implement similar measures, such as:

• Offering tiered electricity pricing to make energy affordable for low-income households. The poor pay less for basic supplies for cooling. First fan free, as a small business in Ahmedabad told the AIDMI team.
• Upgrading energy infrastructure to ensure a stable electricity supply during peak summer months. Find ways to turn extreme heat into additional electricity.
• Expanding renewable energy adoption to reduce dependence on fossil-fuel-based power grids.

A well-structured energy policy can reduce both financial and heat burdens on urban residents, especially the low-income.

5. Investing in Community-Based Heat Resilience Programmes

Community engagement played a significant role in Miami’s research, helping authorities understand localised heat risks. Indian cities can benefit from:

• Launching heat awareness campaigns to educate residents on heatwave preparedness. Focus should be on solutions and not the impact of extreme heat.
• Creating neighbourhood cooling centres in schools, libraries, and community halls. New structures are not needed. The reuse, repair, and revival of existing structures often save time and money.
• Encouraging public-private partnerships to implement large-scale urban cooling projects. Large scale does not always mean a single corporate project. Large scale also means small, local, community or small business-initiated urban cooling projects.

Community-driven approaches ensure that heat resilience efforts address real-world challenges effectively. Network such community initiatives to multiply impact.

Conclusion: Indian cities can learn valuable and urgent lessons from the Miami study by integrating heat-resilient housing, affordable cooling, sustainable energy policies, and community engagement into their urban planning. By proactively addressing residential heat and energy burdens, they can create safer, cooler, and more sustainable living environments for millions of urban residents by the summer of 2025.
