Tonia & Chiara
You have decided to clean your house after work. You need half an hour to vacuum the whole house. You use a vacuum cleaner with a power of 1600 watts for this purpose.
Besides, the TV has been on for two hours. The TV consumes 70 watts per hour.
How many kWh have you consumed by vacuuming and watching TV?

- Was ist die Wirkung (effect), welche die Gruppe mit Ihrer Aktion genau auslösen möchte?
With our project we want firstly to show how harmful glacier melting in Switzerland is and in a second step find out solutions to reduce glacier melt worldwide.
- Was sind die Mittel (techniques), mit welchen die beabsichtigte Wirkung erzielt werden soll?
For our project it is very important to record the results in pictures, videos and texts. Then, we take surveys. Last but not least, the most important thing is to conduct interviews and to incorporate the results in our project.
- Mit welcher Strategie (steps) soll diese Wirkung erzielt werden?
Generally explained, we try to work with our pending list.
On short time terms: We use our brainstorm.
On long time terms: We use graphics, surveys and the results won by the work with our contacts in Switzerland and in the foreign countries (for example Island).
- Wer ist das Zielpublikum (audience)?
Our target audience are students and experienced researchers from universities, specially experts of glaciers. We hope moreover, that some students, who are interested in this area, can help us with sharing and debating our project.

Heating an icehockey rink
Excel Energy found has written, that there is around 2'000 kWh used to heat an icehockey rink (Kunsteisbahn) day by day. This might be an abstract amount of energy for a normal citizen. What do you think, how many typical cell phones could be charged with the energy which is used to heat an icehockey rink?
Calculation data
As I have already noted, an ice rink needs around 2'000 kWh per day. A typical cell phone needs 0.01 kWh to charge.
Your Solution
Approximately ___ cell phones could be charged with the energy which is used to heat an ice rink.

Global Bitcoin Electricity Consumption
The Cambridge University estimated (since the exact calculation is difficult) the global electricity consumption of Bitcoin mining around 121.36 Terawatt-hours (TWh).
What do you think? How long could the city of Zurich could be supplied with this amount of energy when we take the consumption data of Zurich for 2018 for example?
The city of Zurich could be supplied with energy for approximately _______ [years]. This is ridiculous!

An electric vehicle/car travels at an average speed of 54 km/h, consuming 240 Watt per 100 km on average.
The total distance is 237 km. How much energy is consumed during the whole distance in kWh?
In addition, the driver eats a pack of gummy bears containing 250g. The gummy bears have a nutritional value of 340 kcal per 100g.
How much kcal are consumed by the driver and the vehicle during this distance?
