@Ed, cooling loads drive
@Ed, cooling loads drive Louisiana’s electrical consumption (as well as a lack of code enforcement I’m told). Much of California has relatively small cooling loads and energy codes are much more stringent. Even some plug loads are regulated.

Wish I could say the same
Wish I could say the same about our recent visit to Eleuthera in the Bahamas. Diesel generated grid power averaging about 30c/kWh, not a single wind or solar farm or even rooftop solar installation did I see despite steady trade winds and ten hours of sunshine most days. I was told that not only is there no govt. support for renewables, solar panels were taxed at 50% until just a few years ago. Beautiful island, lovely, struggling people.

David, it seems a lot of us

David, it seems a lot of us are missing the same 2 or 3 questions. And yeah, based on comments here and a couple of emails I’ve gotten, it seems more people are choosing Florida than Louisiana.

I correctly guessed the question about highest electric consumption Louisiana. With Louisiana and Florida listed among the choices, I figured it could be either one. I chose the former only because I thought it might be a trick question (I imagine most people would chose Florida, right?)

Mark, it is absolutely a

Mark, it is absolutely a “damning indictment” of duct systems. That’s why people should just get their ducts fixed instead of trying to rely on bandaids like smart vents. Will smart vents cause damage in every application? No. Can they ever be a reasonable, low-cost solution? Maybe. I prefer to see solutions that start by addressing the root causes, though, and smart vents generally aren’t promoted that way.

Lee, you’re right! I hadn’t

Lee, you’re right! I hadn’t noticed there are really 13 questions. I assumed their arithmetic was correct, but I should have been suspicious of even that part. In my second attempt (I answered only the first 3 or 4 at first and came back to it later), I clearly missed two but my score at the bottom said I got 11 right and 1 wrong. Hmmmm. Good catch!

Yeah, the Florida/Louisiana thing could be related to income. One thing that argues against Louisiana compared to Florida, though, is that the former (I believe) has more natural gas. I know in the 13 years I lived there, a lot of the places I lived had gas water heaters and many had gas heat.

Yeah, some of the other

Yeah, some of the other pictures were a bit odd, too.

Charles, my phsics days are

Charles, my phsics days are nearly 2 decades in my past now. I remembered that LEDs are pn junctions and the frequency of light emitted depends on the band gap, but I didn’t recall anything about directionality. So I went to Wikipedia just now and found this:

The light is actually emitted equally in all directions from the point-source, but can only escape perpendicular to the semiconductor’s surface and some degrees to the side.
