Forget the vampires. Let’s tackle the real monsters.

Public service announcements on Facebook and Wichita City Channel 7 urge Wichitans to take steps to stop “vampire” power waste. But before hectoring people to introduce inconvenience to their lives in order to save small amounts of electricity, the city should tackle the real monsters of its own creation.

People are probably vaguely aware that many modern electrical and electronic devices consume electricity even when switched off. One source estimates that a cell phone charger consumes 0.26 watts of electrical power even when a phone is not plugged in. While in sleep mode, a flat panel computer display consumes 1.39 watts. A clock radio uses 2.01 watts. A microwave oven while not in use and with its door closed uses 3.08 watts. (These are average values.) A large Samsung smart television on standby uses 0.3 watts.

While appearing to be wasteful, this “vampire” power consumption often has a benefit. If you unplug your clock radio when you leave for work in the morning, you save a few dozen watts of power. But, you have to reset the clock when you want to use it again. If I unplug my Samsung smart television, I’ll probably have to reprogram it to my preferences. If I want save the power my microwave oven wastes, I’ll have to wrench my back lifting it out of the way so I can reach the outlet it plugs in to. That action, naturally, unleashes a cloud of dust bunnies to dirty my counters and floor.

Nonetheless, the City of Wichita uses its Facebook page and cable television network to urge its citizens take steps like these in order to save small amounts of electricity.

How much electricity do you suppose a city street light consumes? It depends on the type of light, but common street lights use from 100 to 200 watts. During the hours when the sun does not shine, we’re generally willing to pay for that in order to obtain the benefits of lighted streets and sidewalks.

But when street lights are burning in the middle of a day, they provide absolutely no value. Street lights turned on during the day provide none of the convenience of “vampire” power usage, such as not needing to reset your clocks and move your microwave oven every day.

So while the City of Wichita uses its television channel to hector citizens into adding inconvenience to their lives in order to save vanishingly small amounts of electricity, the city apparently has no misgivings about using large amounts of electricity to needlessly illuminate the noonday sky, week after week.

As I’ve shown, the city often has street lights turned on at noon on days with no clouds in the sky. (See here for examples.) Yesterday dozens of city street lights were turned on at 2:30 in the afternoon on a sunny day for many blocks in downtown Wichita. This is not an isolated mistake. It is a pattern. (Even if it is cloudy and raining, the street lights add no discernible illumination during daylight.)

There’s something else. Each of us can choose the balance between “vampire” power waste and inconvenience based on our own values. If we choose to use “vampire” power in order to add convenience to our lives, we have to pay for it.

But the Wichita city hall bureaucrats who burn street lights in the noonday sun week after week are spending your money, not theirs.

(Yes, city hall bureaucrats pay taxes to the city just like you and I, so their tax money is also wasted. But because the cost of this waste is spread over the entire city, the motivation for any one person to take steps to eliminate the waste is small. Especially if, like a city hall bureaucrat would, you’d have to actually work in order to achieve savings. But these same bureaucrats and politicians urge you to work harder in your home in order to save small amounts of “vampire” electricity.)

The wasteful expenditures on street lights I’ve been illustrating for several weeks are located in districts of the city represented by Janet Miller and Lavonta Williams. Both express concern for the environment and criticize the purported harm man has caused the earth by emitting greenhouse gases. Here’s an opportunity for them to act on their beliefs.
