The Philips LED bulbs are great, but they recently announced that they were leaving the business. I guess they are getting too cheap.
I'd have to find my smartphone to turn on my reading lamp? I don't have a smartphone.

Huh? I thought they just sold the consumer electronics biz to Funai and kept the lighting business: Oops, wrong announcement. Looks like Philips is selling the Hue lighting business: Presumably, whomever buys it will continue the product line.
No. For Hue, you could use one of these: Notice that it does NOT require power or a battery.
When I was playing with the Hue lighting, I screwed the light into my Ledu desk lamp. It didn't take much to program a few keyboard macros to belch the appropriate control codes. While not perfect, methinks that on-screen lighting control can be useful.
However, not to worry. The next generation of smartphones will be imbedded in your cranium. You may soon have a working light dimmer tattooed to your arm. You could also do IR motion sensing, where the room lights come on only if there's someone in the room. If that's too much, you can command your room lights by voice or hand clapping. There are light switch replacements that include control via RF and internet control. Worst case is to carry a TV-like remote control around. Lots of options that don't require a smartphone.
You might want to cruise the various Smart Home web sites and see what technology, goodies, and toys are available. Plenty to choose from.

It is all just a few lines of code. people should learn Linux, at east bash scripting, and C of course or else be the slave of thsoe who code.. Future, no coding no power. like somebody who cannot write or read. Future is here.

You can't always *get* natural gas at your location -- or other fossil fuels. (unless you want to incur the delivery charges yourself). Do you factor in the cost of transporting the fuel to your location? Or, the cost of the gas "hookup"?
One thing electricity has going for it is that it is truly ubiquitous. Even folks living "off grid" can manage to get *some* electricity!
Personally, I prefer skylights. Annoys the hell out of me to have to burn lamps during daylight hours to get "enough" light where I want it! :-/
Yeah, we looked into a ground sourced system, here. Frost line (if there
*is* such a thing, here) is probably a fraction of an inch. Could even do most of the excavation "for free" (labor typically being the HUGE portion of all of these endeavors).But, still didn't make sense financially. And, the "scare factor" for future homeowners having "the only one in town" (more or less)...
Instead of screwing in a lightbulb, I'll be hunting for the remote, and then for the damned password that my wife installed. Next, hackers will turn off my lights and demand ransom to switch them back on.
Room lighting works fine. Like gasoline powered cars. Neither needs to be fixed.

But it looks cool and retro. Our living room table is often illuminated by a large candle in a big glass. That's probably even more horrendous from an efficiency point of view. In our kitchen is a 1927 Western Electric wall phone. When it rings it probably uses >100x the power of a ringing modern phone. But the sound, the sound ...

The telco doesn't charge you for ring power.

Those old things use about 4x the power of a modern phone. They're REN1, whereas modern phones are normally REN4, meaning you can put 4 of them in parallel on one phone circuit.
NT
I think you have the sense of REN inverted.
The REN equals the loading effect of the ringer on the line, as compared to a reference of a traditional e.g. WE model 500 electromechanical ringer. Larger numbers indicate a higher load. Modern phones often have smaller numbers.
For the example you cite, the low-load modern phones would have REN of
0.25 or so.Add up the RENs for all of the phones, answering machines, and so forth to get the total load on the line. The nominal limit is around
5 REN on a typical subscriber line.
Annoying?
Finally a phone that sound like a real phone. We also have some others, including all-metal ones from Belgium. In contrast to the wall phone which has a crank that I had to disable those can actually pulse-dial.

Probably 3-5 orders of magnitude. But hey, PG&E "only" jacked up the price 8% this year.
No, but to make up for that Missy Bell charges the 6Mbit/sec DSL rate for a connection that tops out at 3Mbit/sec (on good days).

I was getting about 800K from AT&T, unless it rained. They kept calling me to sell me high-speed Uverse, and each conversation ended in them telling me that Uverse is not available in my neighborhood.
I finally capitulated and signed up with Comcast, for TV and DSL and telephone. They claim 50 MBPS, and I actually get about 10. At least it works when it rains.
Their sales people are fabulous liars.

The obvious solution for too much technology is more technology. Instead of you hunting around for the remote control, your personal robot will do the searching for you. Consumerized military search and destroy robot should be especially adept at finding your remotes, car keys, etc.
Slightly more realistically, what you will need is a hyper-remote. Instead of multiple remotes, one remote that duz it all. I have several Logitech Harmony remotes that make a heroic attempt at this. However, you could do as well with a tablet and some software. I vaguely recall a James Bond movie villain that walked around with one of those.
Hackers? It's more likely your home automation system demanding some attention. Here's roughly how it will go: One of my problems is that I have a few wealthy customers that are into home automation. When there's a problem, I get the call, mostly because I'm cheaper than the factory service guys. I've previously expounded on the problems.
If we all had that attitude, we would still be living in caves and riding critters. Progress does have it's price and does suffer from diminishing returns. A cave and horse would probably suffice to meet
90% of your shelter and transportation requirements. We'll never hit 100% because the requirements keep changing. As long as we have gasoline and cheap electricity, the existing room lighting and gasoline burners are adequate. However, there's no guarantee the situation will remain in the future. You're probably safe living in the here and now, until the future catches up with you.-- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

I used to have 1.3Mbit/sec which was ok until I started to use GoToMeeting extensively. The service is reliable when it comes to connecting but their codec isn't very good. It gobbles bandwidth for imaging while audio drops out a lot or becomes next to unintelligible. So I went to the 6M service the millisecond it became available. Turns out they grossly overpromised. After complaining very loudly at least the notorious drop-outs are rare now, seems they can switch around priorities somehow. "We did something on our end and you should be ok from now on".
Very same thing here.
Thing is, we have zero use for cable TV or their VoIP phone. Plus they slobber the coaxes across the turf. On top, where every little critter can snack on the cable jacket.
With our socks you can fly to the moon! :-)
Got my 2nd inductor burn. Why can't companies quantify core losses a little better? Why can't anyone offer video conferencing that is more lean? Why can't mountain bike gear makers build shocks where the bearings last more than 1000 miles? Questions over questions.
