Question

You are excited about the end of the semester to remote-distance-virtual watch the entire three days (4201 minutes total) of all 8 seasons of Game of Thrones with some of your friends. Assuming that you are watching it on a 55" LED TV that uses 100 W of power, how many kWh (kilo Watt hour) will you consume? Assuming the cost of kW where you live is 15c/kW, how much more would you have to pay that month to the electric company? If you are watching in the US, where the emissions are 500 g/kWh, how many extra gram of CO2 did you emitted? Compare your answer to the case if you watch it in China, where the emissions are 750 g/kWh?
To make your answers clear, please enter the answers, with titles for each number. You can also describe partial work in words.

Answer 1

Total time duration of watching GOT is, t = 4201 minutes = 70.017 hours.

Power rating of LED TV is, P = 100 W

Total Energy used while watching GOT is, E = Pt = (100 W) (70.017 hours) = 7001.667 kWh

The cost of electricity is 15c/kWh, therefore the extra electric bill would be = (15c/kWh) (7001.667 kWh) = $ 1050.25

In the US, the emissions are 500 g/kWh, then for energy consumption of 7001.667 kWh,

the extra CO₂ emitted = (500 g/kWh) (7001.667 kWh) = 3500.833 kg

In China, the emissions are 750 g/kWh, then for energy consumption of 7001.667 kWh,

the extra CO₂ emitted = (750 g/kWh) (7001.667 kWh) = 5251.250 kg
