Not much to add there - I completely agree. It is interesting to see that people who encountered supply shortages of any kind are much more critical to our current generouse use of ressources. We have this initiative here in Switzerland, called the 2000W society. The idea is, that we cut down from our current total energy consumption, expresses as a power, of 6000 W per person (average Europe; approx 10,000 W in the USA). First, I thought that this is a kind of utopic goal - till I realised that this was the energy consumption in the 60s! And they lived quite well then...

I have relatives in Switzerland, just came back from there this summer. I rarely see so many solar cells on top of roofs as in Switzerland. The Swiss gov actively subsidizes solar cells. The fierce independence of the Swiss is demonstrated in many ways and is simply a reflection of Switzerland itself as the "Confoederatio Helvetica" - the Latin name for the confederation of the Helvetians. Note that Switzerland is NOT a member of the European Union! Long Live the Swiss Franc!

ok, enough of politics....
When I commented on the extensive solar cells on house roofs in Switzerland to an Austrian school teacher in his house in southern Tirol, he said that the Austrian Gov gives a very low subsidy for energy upgrades. On the other hand, his oldest son was a flashaholic and had modified various Fenix and other brands of flashlights to his interests, and had them on display in his room! In Germany where my other relatives live, the solar cell subsidy seems to vary widely by the state the people live in.
Back to the topic of batteries - I fully agree with you that those people who have experienced supply shortages tend to be much more careful of their supply and consumption. On the mountain "Calanda" above Untervaz in Switzerland, a couple refurbished a stone cabin set into the mountainside far from any mains electric grid. The "cabin" had absolutely beautiful interior wood finishing will normal amenities - and a large solar cell panel on the end of the house with a two large storage batteries and an inverter inside the house. Last summer I was sitting sipping a beer with him outside and I asked him how well the solar panel served him. He said that the only time the batteries were fully discharged was when they played cards all night long and lost power about 0500.

Most of my relatives and acquaintances in Germany, Austria, and Switzerland can find a working flashlight quicker than the average US citizen!
As for a whole-house electric consumption, my single-family one-story house has an average electric consumption of 150KWH/month, so I already passed the 2000KWH/year level. The goal of energy efficiency in at least one state in Germany was set at 1500KWH/year. That level of electric consumption will be difficult to reach for even me without changing the house!
However, we need the flashaholics and experimenters to push the limits of both batteries and LEDs to drive innovation. The rest of us can purchase the latest lights and batteries to fund the early production. and then maybe we will also realize how far we have come from a 2D flashlight with a standard filament bulb of the 40's and 50's!
