Would a priority system for each households power help a power grid?

Also how would you prioritize your electricity usage? Instead of rolling brown or blackouts? Where everyone is given a little bit of power to use as they see fit?

For example:

My highest priority to lowest:
1) Bathroom lights
2) Freezers and fridge’s for food
3) Clocks and radio
4) All other lights
5) Power outlets
6) Internet
7) Cable TV
8) Air conditioning
9) Laundry machines
10) Everything else

How would your prioritize your power usage better?
