In this task, my goal is to show you, how much kWh a plane needs.
A Boeing 747-400 carries 416 passengers. For a route of 14,200 km a plane needs 240,000 litres of fuel. So a person therefore needs about 6000kWh.
Calculation: 14'000/416*10kWh=6'700

In our IDAF we deal with the topic of solar (solar energy).
Initial situation / Given:
1 Photovoltaik Paneele = 300 Watt
n= 8 PV (Anzahl Paneelen)
Roof side: south
Daytime sun summer: t = 15h ∅
Efficiency (Wirkungsgrad): 65%
Daytime sun winter: t = 9h ∅
Efficiency (Wirkungsgrad): 45%

IDAF Task 3:
An electric car (VW e-golf) consumes approx. 12.7 kwh per 100 km.
a modern heat pump dryer (tumble dryer) requires approx. 2 kWh per wash cycle. This means that for the same energy output, you could run it about 6-7 times.

This post is about the energie consumption in Thailand and in Switzerland. It is very interesting to see how big the difference between these two countries is.
- Energie consumption at a normal household in Thailand in a year: 168.3 billion kWh
Energie consumption in Thailand in a year per person: 2'422.26 kWh
- Energie consumption at a normal household in Switzerland in a year:
58.45 billion billion kWh
Energie consumption in Switzerland in a year per person: 6'914.25 kWh
Numbers from 2016
A log house of 120m2 inhabited by a family of four has generated 19.300 kwh [teacher's note: it's kWh] of electricity in 2 years, but has consumed only 8.800 kwh.

The distance between Switzerland and Cuba is 7.982 km.
If we take a Boeing 747-400 with 416 Passengers we need 120'000 liter Kerosin to fly this distance. One liter Kerosin is 10 kWh. If we divide it by the amount of passenger that are in the plane we you would calculate as followed:
120'000 liter Kerosin = 288.46 liter Kerosin per passenger
416 passenger
288.46 x 10 kWh/liter = 2'884.61 kWh per passenger
So one person consume 2'884.61 kWh to fly one-way from Switzerland to Cuba.
Fact:
The average energy consumption for all flights without motion platform was 0.308 kWh per operation. In the flights with motion, this result was 40% higher and amounted to 0.431 kWh.
Formula:
0.308 kWh x 3.6e+6 = 1108800 joules
