Power monitoring can still be useful to help prevent you from slipping back to inefficient usage. There are a lot of measures that can reduce people's power usage for a short period of time. For instance, advertisements to ask people to turn off unused lights can have a temporary effect on power usage. Making those savings last is much more difficult. Hopefully ongoing power monitoring can help there.
