Green Energy Production to Reduce CO2 Emissions
Killington Resort in Vermont, USA is enrolled in the Cow Power program, a completely local form of renewable energy made in Vermont. Staying with Vermont tradition of buying local, the K-1 Express Gondola is powered solely by manure from local dairy farms. In the process, this reduces greenhouse emissions produced by cows and expands the use of the readily available, renewable resource in Vermont.
Geothermal Heating from Underground
Geothermal Heating from Underground is increasingly used by on-mountain buildings in ski resorts to provide CO2 neutral heat. The Rud-Alpe mountain restaurant and the staff accommodation at the Balmalp in Zug (Lech Zurs ski area) is one of many heated using geothermal heating.
Geothermal Heating From Water
Badrutt’s Palace Hotel heats its halls and suites using heat extracted from Lake St. Moritz, as does the neighbouring municipal Grevas School. The result: savings of around half a million litres of heating oil a year, and a reduction in CO2 emissions of 1,200 tons (a cut of 75%).
Green Electricity From Cheese Production Waste
Europe’s highest-altitude dairy, the Lataria Engiadinaisa (LESA) in the Swiss Engadin, sends whey left over from the cheese-making process to generate electricity. The liquid that the dairy produces – some 4,000 tons a year – is no longer transported to the lowlands for disposal but is taken to the SAX waste water treatment plant in Samedan/Bever, where it is used to generate some 280,000 kWh of electricity a year.
Green Electricity From Organic Waste
Three farmers from St. Moritz, Silvaplana and Sils have teamed up to offer a means of disposal for kitchen and restaurant refuse, green waste, manure and liquid manure in a modern, environmentally friendly manner – and at the same time to carry out and support projects in organic farming. Bio Energina AG’s first project was the construction of a round, 400-cubic-metre silo at the waste water treatment plant in Silvaplana / Surlej. The biogas facility produces around 35,000 kWh of electricity a year for some 150 to 170 households.
Solar power systems tend to work much more efficiently at higher altitudes than at ground level. Ever more ski areas have ever more solar power. In Zermatt photovoltaic panels located 3,800m (12,500 feet) above sea-level produce 80% more electricity than panels at sea level due to the clear air and extra light reflection from the surrounding environment.
In 2007 a heat recovery system with concrete core activation was incorporated into the new section of the Alpenrosenbahn bottom lift station building when it was built in Austria’s Skiwelt area. The administration building is heated in winter using the recovered waste heat from the pumping station of the snowmaking system and transformer station. Thanks to this system, 27.88 tonnes of carbon dioxide is saved every year.
