I look at it like this :
There giving you the heads up before there's a major outage. Some people waste alot of Electricity. Porch lights on day and night or on earlier than they need to be. Street lights on earlier than they need to be . Same thing with the parking lights at work . Small Appliances at home that draw current even when not in use . It's just a friendly reminder to conserve energy which we are all guilty of. Plus it saves money on Utilities .
Your average household has no idea how much energy it, and or what individual items consume, but only look at the totals on a set of bills every month.
Ask a guy how many KWH, Cubic feet/ therms of gas, or actual gallons of fuel they used and they cant begin to tell you.
