As the Wikipedia article highlights, the average Swiss uses about 5kW (that's 5kWh per hour), of which only about 10% are electricity.
Similarly, about 10% are car usage, or about 0.5kW. If we take the average car to develop on average 50kW, and assume an efficiency of 1 (for the sake of the argument), then they use a car around 1% of the time or about 15 minutes a day (less if efficiency is <1, as it is).
ETA some more reference points:
A human eats around 10,000kJ per day = 86400 seconds, let's call it 100,000s, so 10,000kJ/100ks = 100J/s = 100W, about as much as a bright lightbulb (the old fashioned ones, not LED).
The sun gives us about 1kW of power per square meter. Say photovoltaic cells have an efficiency of 10%, and the sun shines 6 hours a day (=25%), then we are talking around 25W/m².
So, the average Swiss uses the energy corresponding to about 50 people working for him or 200m² of PV, the average US citizen of 120 people or 480m² (5000 sq feet), and the goal here is to push it down to 20 people or 80m² PV.
