4. PSE “Customer Feedback”
This is Great! I have been monitoring our energy usage since Thursday and have noticed a change in the way we are using it just by being able to see it online.  We've lowered our thermostat, shut off lights that we aren't using, giving the kids baths during the day (during economy rate) instead of at night (expensive rate), and doing laundry and dishes during the economy time.  This has been so helpful for us.  Hopefully, we'll see a drop in the cost of our bill.  Thank you for the time and effort you have put into this web site to help us save money.
This is a great idea! Our family started referring to this site two weeks ago during the holidays.  We called a family meeting and  developed a collective understanding of the differing costs of power during a 24-hour  daily and weekly cycle.  We have reassigned the timing of household chores to take advantage of the economy and bargain hours for power. (I.e. our Son,  who arrives home from school at 3 p.m., is now responsible for starting the clothes dryer, rather than waiting for the adults to get home and tend to laundry between 6 and 8 p.m.)  That's just once example...we've also lowered the temp setting on our water heater and thermostat and we've changed the days and times when we utilize  our exercise/ hobby room so that this "play" area is heated during the economy and bargain hours/days.  This is phase one.  We know there's more that we can implement, but it's a start.
