IFA Berlin Recap Part 2: More Diverse Sustainability Approaches

A big electronics trade show in Berlin this week showed how far heat pumps and induction cooktops have come in Europe, where they're now the everyday norm rather than a selling point. A few things stood out for anyone thinking about home upgrades. Several appliance makers, including Bosch and Gorenje, focused on cutting the carbon footprint of manufacturing itself, not just how efficiently appliances run once installed. Heat pump makers like Midea and Chigo are shifting to a refrigerant called R290 (propane), which is far less harmful to the climate than older refrigerants if it leaks. That's a detail worth asking about if you're shopping for a heat pump, since the refrigerant matters for its environmental impact over the unit's lifetime.

Beyond appliances, a company called Eurom showed infrared heaters that warm surfaces and people directly, similar to sunlight, rather than heating all the air in a room. The idea is you could keep a whole home cooler overall while warming just the spots where people actually sit, which could cut heating costs. Other exhibitors focused on simpler fixes: repairing appliances instead of replacing them, recycling plastic film into new products, and even a cheap misting attachment that clips onto an existing fan for evaporative cooling, which could delay the need to buy air conditioning.

None of this points to one single upgrade everyone should make. The takeaway is that efficiency gains are showing up in many small, practical forms, from refrigerant choices to heating strategies to simple repair options, and it's worth watching which of these ideas make their way to US markets.
