Rising temperatures boost demand for energy-efficient cooling solutions

Rising temperatures are increasing the demand for cooling, but this leads to greater reliance on air conditioners, which contribute to global warming. With severe heat waves becoming more common, keeping cool is vital for health and productivity. Scientists warn that a temperature rise of just 1.5 degrees Celsius could put billions at risk in the coming years. Air conditioning may seem like an easy solution, but it adds to the problem. These energy-intensive appliances can leak harmful refrigerants that further harm the planet. Lily Riahi from the UN Environment Program states that the current cooling methods are major contributors to climate change. In 2024, electricity demand surged as extreme heat drove air conditioner use to a new high. Renewable energy accounted for a significant portion of this demand, yet much electricity still comes from fossil fuels. The International Energy Agency (IEA) estimates that without efficiency improvements, energy needs for cooling could triple by 2050. Riahi emphasizes that the growing reliance on air conditioning could overwhelm electricity grids, leading to potential failures. To tackle this issue, we need better cooling methods and designs for buildings that reduce the need for AC. Awareness of energy-efficient options is lacking, as are financial resources for these technologies. Innovative ideas for keeping cool are already in action. Projects in India help low-income communities stay cool with simple, cost-effective measures. For example, painting roofs white can significantly lower indoor temperatures. Similar projects in Egypt focus on traditional methods for building design, showing that local knowledge can help combat extreme heat. Architect Sarah El-Battouty highlights the need for a shift in architecture to naturally prevent heat. Sustainable building materials and designs can keep temperatures lower without relying heavily on air conditioning. She believes this focus on cooling should be integrated into global climate discussions. Overall, finding effective cooling solutions is crucial as temperatures continue to rise globally. The conversation around cooling should be as important as discussions about renewable energy.
