• Fast 20% Nettostrom (Export bereits abgezogen) aus
tschechischen und anderen Braunkohle- und
Kernkraftwerken
• Durch Ankauf von Emissionszertifikaten exportieren
wir Treibhausgase in die Nachbarländer
• EU Vorgabe für 2030 (-40% gegenüber Kyoto) ist
chancenlos
• Hinkley Point mit 12c/kWh subventioniert
• Solarstrom mit 26 c/kWh durch
Ökostromförderbeitrag (zahlt jeder von uns mit
Stromrechnung), Holz mit 13c/kWh

Energieaufwand Beschneiung
• 2014 in Österreich ca 20 000 Beschneiungsanlagen mit
ca 20 kW Leistung
• In 400 h soviel wie zwei Haushalte im ganzen Jahr
• Wasserverbrauch von 600 lt / min
• Für 1h Skipiste Grundbeschneiung 10e6 lt Wasser und
30 000 kWh
• Kosten der Beschneiung macht ca 15% des Skipasses
• Schladming: 700 Kanonen, 150 000 m3 /Tag, Kosten
ca 90 k€/Tag
• In letzten 10 Jahren 4500 Kanonen installiert
• 70% aller Pisten in Österreich beschneit
• 1,5 - 4,5 € pro m3 Schnee
Pub Outdoor Gas Radiators
• 32 radiators operating for 10h/day
-- 640 kWh
• Equal to consumption of 50 private
households

Wired phones are dead, mobil phones depend on the battery life
TV, Radio without batteries fail
Internet is dead as routers fail
Rail transport fails, passengers have to be evacuated from tunnels
All gates from and to car parks do not open
Gas stations fail as pumps do not work
Elevators and mobile stairways fail
Home and street electricity supply fails, streets and tunnels are dark
Heating and AC systems fail
Industries are stopped
Water supply fails due to pump failure
Waste water discharge does not work
All farm animals are in danger if heating fails
All shops have to close as cash points do not function
All banks and money dispensers do not operate
Hospitals have to reduce intensive care as they run on emergency
diesel
Public intervention teams (police, fire brigades, ambulances) have
drastically to reduce their services to urgent emergency cases
What you should remember
• Impact of investment costs on
electricity price (higest-lowest)
• Impact of fuel cost on electricity
price (highest-lowest)
• Approx. fraction of nuclear
generated electricity in Austrian
grid
• Typical base load power stations
