I have an account with Microsoft’s Hohm.  My energy provider is not setup with them, so I would have to enter all the information in myself.  The interface is simple and clean.  I like it.  They also give you several recommendations on how to reduce your energy usage, like cleaning your air ducts.  The nice things about the recommendations is that they provide an estimated cost, annual savings, and annual CO2 benefit.  Microsoft also has a community section for Hohm, but it is more informative than connecting with other users.

Google powermeter, I do not have an account.  To use this service you have to install a Google powermeter device and install it in your home.  My energy provider, TXU, has offered it to me, but I declined.  I already have a programmable thermostat in my house.  I do not want to buy a new one just so it can give me some reports.  Although, having it give me a breakdown by hour of my energy use would be cool.  I also do not know what or who will be able to connect to that device.

For now, I will use Hohm and enter it myself.

I told you I would write about it.  I am just a little slow.
