To summarize your post.
"Those measures won't cure the problem. Why do anything, just continue as we are"
"as we are" =3D raping the planet.
Yes, there is overpopulation which needs attention also but advocating doing nothing about conservation is stupid.

Yep and thats exactly how it should work.
When the combined lifecycle energy, material and labor costs, (which are all included in the economic cost) of any new technology becomes better than the life cycle cost of the older technology, then you won't have to force people to use them.

In a year or two, all of your CFL complaints and CFLs will be history too. In the past two months, I've seen a big rise in local office space being finished out in ALL LED lighting. It's instant on, it dims, it can change color from red to violet, and it makes CF look like a real energy hog.
LED's aren't at CFL prices, yet, unless you average in the
10-20 year life. Lighting designers are acting like kids in a candy store.
No reason to retire it, run it 'til it dies, converter boxes for Analog tuner TVs are starting to show up now.

I agree, especially in areas where electricity is produced by hydroelectric plants. It takes just as much water to turn the turbine whether the generator is producing 1 megawatt or 150 megawatts.
Politicians want us, the ones who care, to assume all the guilt and do something. Yet to you think for a minute that Las Vegas will ever change out their lights for more efficient ones? Or any government limit each family to only one car? Or the airlines cut back on the number of flights? No, instead they'll all keep on doing business as usual and ask us to change out a light bulb or two.

Not to mention, WHO's on an antenna anyway?

Hmmm, I am waiting for LED bulbs.
Check the power consumption of that new LCD vs. the CRT and you may well find there is little difference between them.
Price isn't the only factor, functionality is a bigger one.
The early CFLs were crap - slow start, long warm-up, hideous color temperature, too bulky to fit in many fixtures, etc. The current CFLs are vastly better than the early ones and that is the primary factor in people adopting them, not price. Since the early units were so bad, a lot of people were turned off to CFLs and waited well past the time CFLs got good (or are still waiting) to adopt them.
LED lamps are in a similar position to the early CFLs, they just aren't ready for the mainstream yet due in large part to issues with light distribution and color temperature. CFLs were an easier fit for light distribution as they are an omni directional source like an incandescent is. LEDs are very directional and getting an even omnidirectional distribution with them hasn't really been worked out from what I've seen. LED color temperatures are also terrible as is their spectrum.
When they get LEDs that either individually or in a group can achieve the relatively warm color temperature that most people want (vs. the harsh bluish high color temp of most), and have good, even omnidirectional light coverage then the mainstream will consider them. Given the pace of LED technology lately, I don't expect it will take that long for these issues to be resolved, but I haven't seen any LED lighting that would be remotely acceptable to me for general residential use so far.
I'm retiring my CRT TV mostly because it is an energy hog. By doing so, I'm not only reducing energy use, but I get a bigger TV, AND a bigger living room. How cool is that? Very few people need to worry about the change to digital, as far as hardware, because that will be addressed by their cable or satellite providers. People who watch TV broadcasts over the air are in the minority.
Already checked. There's a huge difference. You may be confusing LCD with Plasma, which uses a lot more energy.
No, I'm not. Plasma does indeed eat power, but many LCDs are not that different from CRTs. The difference gets greater with larger CRTs and LCDs, but for smaller stuff it can be surprisingly small.
Sorry, I disagree strongly. When you add up the cost of replacing all of the lamps at once in an average sized home at $15 a pop, versus $2 a pop, it's a radical difference. Cost was a monumental hurdle, which both manufacturers and retailers have acknowleged. Adoption of CFL's was slowed more by price than anything else. Once the price came down drastically was when you started seeing them everywhere.
I have a few LED's, and they are great. I don't have any incandesent lights an my sailboat, either and if you shop around you can get LED's with very pleasant characteristics now. It will only get better. They are going through the same thing as many new technologies. They start out with very high prices early on, before they have really been perfected. Lack of sales during that period slows development. At some point they hit critical mass and then prices plummet and the technolgy improves rapidly.
Then you just haven't been looking hard enough. 8^)

people who can't afford cable or dish TV.
I have an antenna--that's all I need to watch PBS which is the only programs I watch anyway. And, I get high definition (from the antenna) on my 50" plasma screen. Not a question of cost, just don't need cable nor an ugly dish.
Well of course, smaller TV's use less power. How silly of me to overlook that.
Meanwhile, you ARE confusing Plasma with LCD's. They are noticably different when it comes to power consumption. Either that, or you are including LCD projectors, which are not part of this discussion at all.
Hi, Nearby town of Banff installed LED street lights with solar panels. Very cool looking light and it is cool running, no bugs get attracted kep them clean. Cost a lot initially but for the long run, it's winner. LED bulbs now are expensive but with time the price will come down. I have a few small ones in the house, they use couple Watts per bulb.
Here's a quote to ponder from Walter Williams:
"I'm afraid most Americans view such a liberty-oriented solution with hostility. They believe they have a right to enlist the brute forces of government to impose their preferences on others."

Cost is certainly a factor, however you could give the CFLs away for free and people would still not use them if they had not progressed and fixed all the faults of the early ones.
It takes both price and performance for general adoption to begin.
I've not seen a single LED unit with either acceptable light distribution or acceptable color temperature so far. Care to suggest a unit I should look at that solves those problems?
My nephew works in maintenance in an Atlantic City casino hotel.
Thousands of lights.... "on" 24X7 They switched to CFLs... Significant savings on theri electric, and measurable savings on A/C.
Their only prob. is the cheap bastard hotel tenants who steal the bulbs.....
light.
I spent some 15 years in the video world, I'm quite familiar with the different technologies. Put a Kill-a-Watt on the current CRT and record the kWh used over a normal week and then do the same with the new LCD. Report back on the difference.
