A typical incandescent lamp (traditional light bulb) consumes 60 watts of power. How much do each of a compact fluorescent and LED lamp consume, in watts, to produce the same amount of light?
-
Sorry, that’s incorrect.
A typical incandescent lamp (traditional light bulb) that consumes 60 watts of power produces around 800 lumens. A compact fluorescent lamp emits the same amount of light while using only 13 watts. And an LED lamp consumes only 10 watts to give off the same 800 lumens.

What are ways that electricity system operators match power needs to generation on a day-to-day basis?
- Turning on or off adjustable, load-following generators
- Turning on or off short-term "peaker" plants
- Initiating demand-response actions, such as adjusting thermostats for customers who have agreed to it.
- Initiating energy storage, such as pumped hydro or battery storage.
- All of the above
-
Sorry, that’s incorrect.
Load-following and peaker plants, demand-response and energy storage are all ways that grid operators can adjust generation to meet demand.

Refrigerators became 70% more efficient between 1972 and 2001, primarily due to regulation. What is a market response to increased efficiency of refrigerators?
- People use their refrigerator more hours in the day.
- People use their refrigerator fewer hours in the day.
- People keep more refrigerators in their house.
-
Sorry, that’s incorrect.
Refrigerators are not likely to be used more or less hours in the day, but people are more likely to have more of them if they cost less to operate.
