5th PEB conclusion: In Europe, PV-PEB can cover 75% of the total energy need

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 today’s level of technology and depending on the general conditions, Europe’s energy need for buildings and individual traffic will decrease to 5000 TWh/a by 2030-2050. As an additional reserve, Europe’s cheap and increasingly excessive wind energy could be better used as regulating energy for PEB and electric cars with help of ecologic pump storage power plants. This renewable energy model with general conditions according to the demand-side management

China is listed with 2002. 5 million tons of fuel oil (17.7%) ^ 2225,000 TWh/a depending on the conversion factor in the Chinese energy sector. In Europe, it depends on which countries are included: with Russia and Azerbaijan it would be even 2965 million tons of fuel oil, i. e. 26.2%; for the EU—including all western European states—about 20,000 TWh/a are assumed.

cWith an average self-supply of 100-200%, today’s energy need in the European building sector of 10,000 TW/awillbe substituted. In future, it will be approximately 2500 TWh/a for the building and individual traffic sector each, depending on the investment scenario.

(necessary also from the electricity consumer’s point of view) can be adopted for all continents with slight adaptations. If Europe is transformed into a "PEB building park”, the total energy need of all heated buildings and of individual traffic could be completely covered with today’s level of technology. Therefore, PlusEnergy Buildings cover 75% of the European energy demand.

6th PEB conclusion: PV-PEB can cover 75% of world’s total energy need

Since physical axioms about solar radiation, gravitation etc. are universal, what is possible in Europe seems possible also worldwide. Therefore, PEB can cover 75% of the world’s energy demand. The measured values from housing and business buildings in Europe confirm the "plans for an emission-free world until 2030” in the study of Stanford by Prof. Jacobson.3 With just one note: Presumably it is not 12.5 TW or even 16.9 TWb that are needed; according to the planned and proven increase in energy efficiency and substitution in the building and traffic sector 6 to 8 TW should be enough. c Instead of 3.8 million of wind installations and 1.7 billion of PV installations, a reduced number will be enough to hold today’s live standard or

With a self-supply of 120% to 200% for new buildings and of 85% to 150% for refurbishments, Europe’s building park will transform from a big energy consumer of approximately 10,000 TWh/a to an energy producer with a self-supply of 120-200% in all buildings by 2030/50. Depending on promotion and legal requirements, the rate of renewal amounts to 1.5 to 2% or more of all buildings. The worldwide energy need of primary energy and final energy is based on BP Statistical Review of World Energy, June 2009, p. 40 ff; International Energy Agency, Key World Energy Statistics, Paris 2009, p. 6 ff.; see Swiss Solar Prices between 2000 and 2009.

to even optimise it by massively decreasing emissions in the cities worldwide. What is already possible in Europe today, might also be possible on other continents.

The Stanford professors confirm that there are enough renewable energies (PV, solar-thermal, wind, hydropower and wave energy as well as biomass and geo-thermal energy) to supply 100% of the world’s energy needs. A new and pleasing, but not surprising phenomenon are the very low future energy costs, that are indicated with 4-5 €cts. a However, the energy price is only important to "energy illiterates”, because they have not understood that the annual energy costs are determined by two factors: price multiplied by amount. As the following example shows, the price for solar electricity can be even 200% higher while the energy bill is still 80% lower. The amount of energy is as important as the price! Unfortunately, many "energy economists” have not understood this simple fact so far.
