Save 75% on electricity?

When i first saw the following stat (as part of the greenpower infographic) i thought two things...

1. Austalia sure consumes a lot of electricity. 2. I wonder if that average looks low because of under-developed nations.

Number 1 is true. Number 2 only partially. It turns out that even Germany is around that world average, according to other data.

Seems that we could make massive cuts into our electricity bills (and greenhouse emissions) just by being more energy efficient.
