Hi everyone, 

I am trying to find a good predictor for my target variable: Annual total electricity consumption of a household in kwh
In the dataset I am using, the values of this label variables varies between 48 and 72145 kwh. 
What do you think would be a good RMSE or Relative Error in this case. 

PS: I tried also with filtering out the examples with annual electricity consumption values smaller than 3000kwh (estimated electricity for the basic needs in a house) but I still got the same RMSE and RE values of about 5000 and 50 percent)

It would be very helpful to get an answer as I couldn't go forward in my work.

Thank you in advance!

    Thanks a lot Lionel for the detailed and quick answer :) 
    Indeed the Auto Model helped in guiding me to what could be good values of RMSE. Thanks for that tip!
    I also found in RapidMiner another performance measure adequate to my prediction task which is the Normalized Absolute Error. It is unit independent, however I'mm not sure how to interpret its values.
