I did. It had little to do with transmission losses, which, IIRC, are in the neighborhood of 10-20%, compared with 60-70% heat loss in internal combustion engines.
Of course, these losses have to be figured in to determine which technologies give you the most bang for your ton of CO2.
Once again you forget to quantify. One estimate is that over 60% of the energy used to supply electricity is lost as heat How many different generators exist in the US? How many cooling towers, How many millions of miles of all types of transmission lines throughout the country? How many motors, light bulbs, computers, on and on, that all lose energy as heat when operating?
One example says if one had a generator, large enough to supply ALL of the electricity for ones own home, one could save 25% to 45% of their cost for electricity. If the average homeowner buy $200 of electricity a month they could save $25 to $45 a month or $600 to $1,080 a year. The only problem is such a generator could cost $90,000 to build
I installed a solar hot water heater in my Key West home. Considering the cost and annual the maintenance, I will have all of my money back if I live fifty more years, if it last that long. I'm close to 82 ;)

Well, duh! What do you expect from something that heats HOT water? ;)
"Moon Goddess"...
I got used to it soon enough. I just don't see it anymore, or at least not consciously. Tomes
"Wickeddoll®" ...
Nah, it is bigger on the inside than on the outside (think TARDIS). Tomes
"Wickeddoll®"...
It is no problem for a full family supermarket trip, for example. It also had a significant space under the rear floor. Tomes
"Cathy F." ...
This is one of the things that I have been wanting for, like, forever. I want the same light dimming feature that the windshield mirror has on both outside mirrors. Always have wanted this. Tomes
Do you hear us, car manufacturers?? We want this feature!
Cathy
Problem is, someone will sue the car makers because the mirror didn't dim when it should have dimmed or didn't undim when it should have undimmed. What in hell did people do when we didn't have remote exterior mirrors? Next thing you'll want is for the car makers to provide you with a chauffeur. A typical dimmie, too soft, too demanding and too whinny. Spoiled perhaps.
Lincoln offered this on the Lincoln LS. Jeep has offered a driver's side self dimming mirror on some models.
Ed
That's a start, but considering I have zilcho interest in a Lincoln or a Jeep...
Cathy
Both outside mirrors dim and tilt downwards in reverse on the Lexus LS and the driver's side self dimming feature is available on some Avalons.
Getting closer...
Cathy
This has been available for several years on BMWs.
True, although I think Cathy is more inclined to buy a Toyota or Lexus than a BMW, Lincoln or Jeep ;-)
But she DID say "car manufacturers". I was just pointing out one more.
Well, in that case, she had better be careful what she asks for!
She may get it?
Cathy...BMWs are great cars. Go for it!
True, except she can't afford a Lexus. ;-)
Cathy
Ray O
Guilty. I didn't know it was available; have never heard anyone talk about it.
So... amended to: Listen up, Toyota!
