-Convert the following values step by step: 
- 
-How much energy does an average household consume per day when consuming an average power of $ 500~{\rm W} $? \\ 
-How many chocolate bars ($2'000~{\rm kJ}$ each) does this correspond to?

-\begin{align*} 
-W &= 500~{\rm W} \cdot 24~{\rm h} = 12000~{\rm Wh}= 43'200'000~{\rm Ws} = 43'200~{\rm kWs} &&= 43'200~{\rm kJ} \\ 
-\text{Or:  }  
-W &= 0.5~{\rm kW} \cdot 24~{\rm h} = 12~{\rm kWh} = 43'200~{\rm kWs}                       &&= 43'200~{\rm kJ} \\ \\

-n_{\rm bars} &={{43'200~{\rm kJ}}\over{2'000~{\rm kJ}}} = 21.6~{\rm chocolate~bars} \\
