Key Concepts:

  • Heatwaves in India
  • Air conditioner (AC) demand and market growth
  • Urban heat island effect
  • Energy consumption and coal dependence
  • Climate change feedback loop
  • Sustainable building practices

1. Heatwaves and Vulnerability:

  • India is bracing for a two-fold increase in heatwave days this year.
  • 80% of India's population is vulnerable to the impact of heat waves, which are claiming more lives each year.
  • Example: Sheetal Kumari's family in a New Delhi slum finds living inside unbearable during summer due to poorly ventilated homes.

2. Air Conditioner Demand and Market Growth:

  • India is set to be the fastest-growing market for ACs globally.
  • The International Energy Agency (IEA) projects over 1 billion ACs in operation in India by 2050.
  • Sheetal's family rents two ACs for $350 for 3 months, as buying one would cost double.
  • AC usage leads to inflated power bills, straining limited finances.

3. ACs and the Urban Heat Island Effect:

  • ACs contribute to the urban heat island effect by pushing hot air outside, making cities hotter than surrounding areas.
  • Rakshit Kotan's Mumbai business, which supplies ACs to daily wage laborers and factory workers, is busier than ever.

4. Energy Consumption and Coal Dependence:

  • Running ACs requires burning more coal, which accounts for 55% of India's national energy mix.
  • During last year's heatwave, AC usage jumped by more than 10% from the previous year, according to Ember.

5. Climate Change Feedback Loop:

  • Human-driven climate change leads to hotter days, increasing the need for cooling units powered by fossil fuels, creating a seemingly endless loop.

6. Sustainable Building Practices as a Solution:

  • Adash Kapoor suggests reducing reliance on ACs by implementing building construction and maintenance techniques that prevent heat from entering buildings.
  • Examples of such techniques include:
    • Thicker walls
    • Walls that reflect heat rather than retaining it
    • Green roofs
    • Lighter-colored walls to reflect sunlight
  • These solutions are often not within reach for families like Sheetal's.

7. Conclusion:

  • India faces a growing challenge with increasing heatwaves and reliance on ACs, which exacerbate climate change.
  • Sustainable building practices offer a long-term solution, but are currently inaccessible to many vulnerable populations.
  • For families like Sheetal's, ACs remain the only viable option for surviving the extreme heat, despite the financial and environmental costs.
