Solar panels are being tested in a solar park on top of the EPFL polytechnic institute in Lausanne, by Romande Energie, one part of a Swiss push to develop solar power
Zurich, Switzerland (GenevaLunch) - Solar panels have the potential to supply far more home heating, including heating water, than previously thought, a new Swiss study shows. “Home heating that relies entirely on renewable energy, leaving untouched the limited biomass potential, is on our doorstep,” an Energy Office statement on the study notes.
Homes in rural areas could have 75 percent of their home’s heating requirements taken care of by solar panels, using wood to make up the difference, the study mandated by the Swiss Federal Energy Office concludes, based on a review of 1,000 homes in the Fribourg area.
Solar energy could supply 13 percent of home heating needs in urban areas, based on a study of some 200 homes in Zurich. The difference is due in large part to the tendency to have several floors in city buildings, rarely the case in rural areas.
Two types of houses were taken into consideration:
- the first a standard home today, eight litres with a 104kWh/m2 consumption = 8 litres heating oil for ambient temperature and 24kWh for hot water
- the second in line with recent energy standards, three litres, with a consumption of 54 kWh/m2 = 3 litres heating oil, 24 kWh for hot water.
Each of these was studied with two options, either a 100-litre thermal accumulator/m2 of solar panel or an optimized thermal accumulator, which will soon be available, thanks to technological progress.

Aminona's existing 3 towers (white) likely to see several more as part of new luxury resort project
Sierre, Switzerland (GenevaLunch) – The controversial CHF350 million resort complex that Russia’s Mirax company is planning to build in Aminona, near Crans-Montana in canton Valais, is suddenly looking greener than its original plans showed.
Swiss environmental groups in December 2009 filed appeals against the project to build a 2,500 resort with several towers and a five-star hotel plus 32 chalets.
WWF and the Swiss Fund for the Protection of Nature said at the time that they “fear[ed] a fiasco for nature and the surrounding countryside, as well as for the region itself.”
Concerns focused particularly on the supply of drinking water and protecting the dry prairies in the region, which are considered to be of national importance.
Mirax announced plans in 2007 to build on the 60,000m2 stretch to the east of Crans-Montana.
Mirax’s emphasis has now shifted from luxury resort to luxurious and green: the company says it will invest CHF250 million in green technologies for the resort, reports Le Nouvelliste, Valais newspaper.
The total expected cost of the resort has risen to at least CHF600m, with Mirax saying it will be not just the most ecological resort in Valais, but in all of Switzerland.

Updated 16:30 Geneva, Switzerland (GenevaLunch) – Wednesday was the 39th annual Earth Day in the US, which explains much of the flurry of talks, blogs and activities designed to get us thinking along greener, cleaner lines. The Huffington Post carried blogs by filmmaker Robert Redford on taking a stand, and author Michael Pollen, who praises the new vegetable garden at the White House, the first since Eleanor Roosevelt.
Meanwhile, here in Geneva, the US Mission to the United Nations put into operation a piece of new technology that will contribute significantly to Geneva’s reputation as a green city and to the United States government’s efforts to reduce the carbon footprint of its embassies and missions. The State Department sees Geneva as an ideal place to spotlight emerging green technologies because of its reputation as an environmental centre, US staff say, but also because during the past four years the Mission has developed excellent working relations with the canton’s energy department and Geneva’s SIG (industrial services) department. “They’re very forward thinking,” says Michael Christensen, a green engineer from the US State Department, who praises SIG’s efforts “to do everything they can to prevent fossil fuel use.”
Hillary Clinton met with international diplomats in Washington to discuss “Greening Diplomacy” where she mentioned the US Geneva’s Mission and its new air conditioning system.

The Mission’s new air conditioning system gives the US an opportunity to showcase cutting edge technology, an air cooling chiller system that uses no lubrication oil and a minimal amount of refrigerant in comparison to typical chilling systems. It is a long-awaited commercial application of a solution to a decades-old engineering dilemma of how to maintain a magnetic levitation motor shaft within microscopic tolerances. Magnetic levitation dates back to the 1940s, but nanotechnology was required for this step.
