How Did California Determine CRT TV Energy Use ?

The California Energy Commission's TV energy use FAQ on their proposed regulations says:

How much wattage do different types (CRT - cathode ray tube, liquid crystal display - LCD, plasma) of televisions use?
It's hard to compare CRTs to LCDs and plasmas. On average, CRTs use 0.23-watts per square inch of the screen, LCDs use 0.27-watts per square inch, and plasmas use 0.36-watts per square inch. Below are comparisons of the "average size" of each type of television and the wattage they use, and a comparison of wattage used by a 42-inch LCD versus a 42-inch plasma.
There are few direct-view CRTs that are as large as the big LCDs and plasma TVs. A 40-inch (diagonal), direct-view HDTV is the industry's largest direct-view cathode ray tube. It uses 280 watts while in operation and only one watt in stand-by mode.

So how did the CA Energy Commission arrive at 0.23 watts per square inch for CRT televisions? I'm still looking. According to the staff report, that power usage information came from the Pacific Gas & Electric (PG&E) study "Analysis of Standards Options for Televisions: Revised Proposal" which was put together to help the California Energy Commission. Reading the PG&E report, however, shows ... zilch on CRT TV energy use! Separately, I did find one private "Pro Bono Statistics" blog, based tests they describe as less than rigorous, of two Sony WEGA CRT TVs that shows 0.23 ^W/_in² and 0.29 ^W/_in²; and notes that CRT televisions are far more efficient that CRT monitors! NRDC's presentation has some data too, but again uses less than rigorous methods.

CNET has tested more than 100 television models, using their own lab method, but they have no CRT data because they have only tested non-CRT televisions televisions :( In their chart, rear-projection was the energy efficiency winner at around 0.13 ^W/_in² (sort by "Per sq in.") and rear-projection is not even listed in the CA FAQ.

In Nov 2008, Energy Star v3.0 added TV ratings in a technology agnostic fashion:

CRT TVs have such a small market share now that the California Energy Commission probably feels it's not worth digging into, however, if CRTs really are so energy efficient, perhaps we should look at them again!

General Motors Trying Hard...

Normally, General Motors gets pilloried for their environmental record. Apparently the public notices them primarily as owners of the environmentally anathema Hummer, Escalade and Yukon monikers. GM's marketing department also used to lead with these brands, so why should we give them kudos for trying hard environmentally?

Well, all companies have to be profitable to stay in business. The existing US regulatory scheme, customer demand, and artificially low gasoline prices all force auto manufacturers toward bigger and bigger vehicles. All companies try to sell more of their most profitable products; GM does that too and the big SUVs bring in the highest profits.

Wait?! I hear a heckler shouting that "Toyota and Honda don't sell large trucks; that means they're green!". Not quite; Toyota and Honda would love to sell more into the highly profitable large vehicle segment and Toyota has consistently increased the size of it's trucks over the years to move into that market. Honda introduced the Ridgeline "truck-like" vehicle to compete here as well. They're not succeeding, however, because Ford, GM and Chrysler out compete them. No marketer would say "Our big trucks are losers. Come check out our tiny cars." - instead they simply say "Come check out our environmentally friendly cars!" (and secretly hope you'll buy their "big" trucks).

If folks really want an environmentally friendly auto fleet they can easily make that happen: a) vote with your pocketbook and buy high mileage vehicles to replace SUVs (we're starting to do just that) and b) work to elect politicians that will fix today's broken regulatory system so that the most environmentally friendly cars become the most profitable cars.

Among all of the car makers, GM has the best track record at introducing economically sensible environmental solutions; unfortunately, customers didn't notice those offerings in their stampede to the SUV aisle. For example, in 1989 GM started marketing the GEO Metro (45/50 mpg!) with room for four and fuel economy on par with the Prius without the high tech, high cost hybrid system. GM's EV1 then became the undisputed environmental champion until lobbyists (including GM's) killed the CARB ZEV mandate. Even then, GM kept introducing environmentally sensible vehicles. The 2005 GMC Sierra/Chevy Silverado Hybrid included idle engine shutoff and regenerative braking. They went on to pursue this very economically astute "mild hybrid" (or perhaps "smart hybrid") approach in the 2006 Saturn VUE Green Line and then added it to the Saturn Aura Green Line and Chevy Malibu. Fickle customers, however, choose less viable, higher cost hybrids and so GM added a "full hybrid" option to the 2008 Chevy Tahoe/GMC Yukon and changed the VUE to a 2-mode "full hybrid" for 2008. Big trucks have a lot to gain from a hybrid drive-train, arguably much more than small cars do, and so once again GM technology is moving ahead of the competition.

On the other end of the market where small, unprofitable cars live, the big three have far less incentive (aka profit) to compete. When profit margins get squeezed, smaller costs become magnified and the increased benefits that GM, Ford and Chrysler provide their union workers mean more in low-end cars than they do in the high profit, large vehicles. Interestingly, if the government provides universal healthcare, it will help level the playing field between union and non-union shops.

GM has been trying to get customers to look their way by offering excellent technical choices, but the customers are more interested in buying giant CO2 generating SUVs instead.

Busted!? 3M Polyurethane Protective Tape 8674 used for Zagg invisibleSHIELD, BodyGuardz, Best Skins Ever...

After a bit of internet searching, 3M's Polyurethane Protective Tape 8674 looks like the "military" material behind the products being sold as Zagg's invisibleSHIELD, BodyGuardz and Best Skins Ever. 3M's wet installation instructions match those vendors' installation instructions and the 3M instructions also include a drawing that looks very much like the vendors' marketing photographs. For the cost of one shield from these companies, you can buy an entire roll of the tape and then cut shields for your whole tribe. That's the downside - you'll have to cut your own shapes. Fortunately, blue-ember.com posted a pdf template for an iPhone skin. Several other shapes are shown on the vendors' sites, however, those might be copyrighted images.

Good luck with your skins and shields.
