How precious is a kWh?

A kWh of electricity means:
  • 1200 electric shaves (> 3 years)
  • Slice 100 breads
  • Drying your hair 15 times
  • 4 TV evenings
  • Listening to 15 CD's
  • Using a (small) refrigerator for 24 hours
  • 20 microwave meals
  • Drill 250 holes
  • 4 evenings of light with 60 W incandescent lamps
  • 20 evening of light with 11 W compact fluorescent light

... or to accelerate a German ICE3 train (8 carriages) from 0 km/h to
14.25 km/h (or from 299.6625 km/h to 300.0000 km/h). The full
acceleration from 0 to 300 km/h takes 444 kWh. The difference is that the ICE3 train can recover most of this energy during braking, while no hair dryer has been encountered so far that can turn dry hair into wet hair and electricity.

Wow, that's a nice statistic. Gives a good idea about the energy consumption to the reader.

Thanks.
