Since this article uses that fluffy "tell a story" writing style, here's the facts in the article stripped out:

1. Air conditioning consumes 10% of global energy and 20% of energy used in buildings.

2. Demand for cooling is expected to increase significantly, with 2/3 of world households projected to have air conditioning by 2050.

3. Dehumidification accounts for over half of energy consumption in air conditioners in humid conditions.

4. New technologies are being developed to improve air conditioning efficiency:

   a. AirJoule by Montana Technologies:
      - Uses metal-organic framework material for dehumidification
      - Claims to reduce energy for dehumidification by up to 90%
      - Still in prototype and testing stages

   b. Blue Frontier:
      - Uses liquid desiccant for dehumidification
      - Being installed in various locations in the US

   c. IceBrick by Nostromo Energy:
      - Energy storage system for large-scale cooling
      - Can reduce annual cooling costs by 30% and associated emissions by up to 80%
      - Only suitable for centralized cooling systems

   d. Gradient:
      - Window-based heat pumps with larger external units for better efficiency
      - Currently costs $3,800, aiming to reduce to $1,000

5. Electrocaloric cooling is being researched as a potential future technology, potentially 20% more efficient than current methods.

6. Passive cooling measures (e.g., window shutters) should not be overlooked as they cost nothing to run.

7. Current non-centralized air conditioners operate at only about 20% of their theoretical maximum efficiency.
