Sankey diagrams can be used to visualize the breakdown of money / electricity. You have a big base value like the energy used by an average single German in December 2017. Then you build big clusters:
- Transportation
- Household
- Other
and you might be able to split household up again:
- Heating
- Refrigerator
- Computer(s)
- Other
The online tool sankeymatic.com can build quite nice Sankey diagrams with a simple interface.
