Eco-friendly ways to cool homes
The article discusses air conditioning devices and their impact on the environment and cooling efficiency. It indicates that cheap portable air conditioners are less efficient and consume twice as much electricity compared to fixed units, with the additional risk of carbon monoxide gases from gas heaters returning to homes. Meanwhile, split (ductless) air conditioners are more efficient, with prices starting around 900 euros, and include higher-efficiency fixed systems that cost between 400 and 2,500 euros, with low operating costs of approximately 150 euros annually for a 70-square-meter apartment. As temperatures rise, electricity consumption for cooling also increases globally, and it is expected that by 2025, electricity usage for cooling will have increased by 50% compared to 2015. Currently, cooling accounts for about 9% of the world's electricity demand and is increasingly produced from renewable energy sources. The article also emphasizes the importance of environmentally friendly refrigerants, noting that some older air conditioning units using climate-harmful gases will be banned by 2029, with a shift towards more eco-friendly refrigerants in the future. Additionally, it suggests environmental solutions such as increasing green spaces and utilizing centralized cooling systems in cities to help lower temperatures and reduce the environmental impact of cooling.
