I think the following are no longer functional, at least from a public/personal API perspective:

• Wattzon
• MyEnersave
• PeoplePower
• Bidgely
• MyEragy
• Xively

I can send a pull request to nuke them all if I'm correct and if that's helpful, not that removing dead code is rocket science. ;) It is almost 1000 lines of dead code.
