Artificial snowmaking has become essential for many Alpine ski resorts as warmer winters shorten natural snowfall periods. In central Switzerland, technicians rely on reservoirs, high‑pressure systems and app‑controlled snow cannons to keep slopes open — but the energy demand is enormous.

New technology from Swiss manufacturer Bächler promises far greater efficiency, producing snow from ultra‑cooled, high‑pressure water particles while using significantly less electricity. The same innovations are now being tested on the Morteratsch Glacier, where researchers hope artificial snow could slow ice loss and support regional water supplies. As climate change reshapes winter tourism, the race for more sustainable snowmaking systems is accelerating.
