In summary it can be said that PV can be used like no other energy source in three dimensions: • The first dimension relates to energy production: After their use in space, PV solar cells were increasingly also used for terrestrial electricity production—e. g. for solarcars and in buildings. • Second dimension: Solar electricity production […]

The example of today’s total energy need of twelve apartments from 1896 in the old town of Basel shows what can be achieved economically and ecologically even in protected areas in European cities by an optimum PV integration and with high energy efficiency—despite "expensive PV”: Scientific American loc cit. Jacobson and Deluchi, p. 64. Today’s […]

Similar to China, Europe is consuming approximately 20,000 TWh/a. b Today, the average consumption of Europe’s buildings amounts to approximately 10,000 TWh/a. PEB could substitute at least 75% of the average building consumption. Therefore, the building sector will in future only need about 2500 TWh/a and the traffic sector another 2500 TWh/a. c According to […]

The total energy need of the apartment and commercial buildings, according to the OECD making up for 46 to 50% of our total energy need, a will in the future be covered completely by PEB. If future apartment and commercial buildings have an average self­supply of 120 to 200%, the future need of 25 TWh […]

By changing from motors to solar electric drive in individual traffic, efficiency in the traffic sector would increase by 50 to 70%. Today, about 75 TWh/a are needed in the whole Swiss traffic sector. If individual traffic changed to electric drive, 25 TWh/a would be enough. In spring 2010, Renault asked for "electric cars for […]

1st PEB conclusion: PV-PEB supply 100% of the building needs Due to the rejection of a sustainable energy policy, Switzerland has to import 80% of its actual energy needs. On the other hand, it is possible to enlarge several existing hydro-power plants to pump storage power plants for a sustainable us of wind energy excesses […]

1st conclusion: PEB cover 75% of a family’s total energy need Reduction of energy losses by 90%: If from 2010 on all new buildings were built according to today’s level of Central Europe’s building technology, they would have an energy self-supply of 100 to 200%—which is proved by different energy measurements. Refurbishments of apartment and […]

Meanwhile, even energy-intensive businesses show sensational results: Shopping centres that seemed to be hopeless cases with energy indexes of 750 kWh/m2a can be refurbished into PlusEnergy Buildings with a self-supply of 120 to 150% by consequent heat insulation, with high-tech electric appliances, LED lights and mono­crystalline solar cells. a The developers of a building project […]
