    > 'Notice that you have not been asked to switch off anything really inconvenient, like your heating or air-conditioning, television, computer, mobile phone, or any of the myriad technologies that depend on affordable, plentiful energy electricity and make modern life possible.

    I can't address all of these, but computer? I read back in the late nineties that computers dissipate a power level less than a 75 watt bulb, probably less now with power conservation and "green" designs. And cell phones? Miniscule, compared to generating light or heat. Televisions? Maybe old tube type, or really humongous sets now, but in general, I'm under the impression that they don't use that much power. He has a point about air conditioning (in most cases) and heat, but those, plus light, are gross uses of power.

    I'm not convinced that a given individual's electronics would be a substantial percentage of their personal, total power footprint. (There are probably alpha nerds out there who heat their rooms with i-products and only use them in the dark, but I'm thinking not many.)

    The contention seems to be that what you should switch off is measured by convenience rather than actual power usage. This seems an conceptual error.

    I'm very sorry to say that in the late 90's a 100W power supply was generally pretty sufficient, but these days you'll find no shortage of 600W or 1KW power supplies. I don't know how much my current system pulls, but the preceding one idled at about 115 Watts, and I kept it longer than I "should" have because it was relatively efficient for its time.

    Cell phones have also tended to demand more and more power in order to get that full multi-media smartphone edge.

    On the other hand, replacing CRTs with solid-state monitors was a big jump in the other direction, and if you want to really feel all hippy greenie eco-friendly, you can do a lot with a Raspberry Pi and it only pulls about 5 watts. It's no gamer machine, but it still outperforms the desktops of the 90's.

    The grid is not well-equipped to handle rapid transients in load. You can't change the heat output of a coal or nuclear-fired furnace instantly, and if you try, bad things happen.

    If everyone on the grid suddenly opened their breakers at the same time, the resulting backlash would probably cause thousands of steam turbines to overspin and their emergency pressure valves to open, at which point the turbine has to spin down and resynchronize before it can begin producing power again. I guess that would be okay since there is no load, but it would take a long time to get things back in order.

    A steam turbine generation system cannot respond instantly to enormous changes in load over a short time interval.

    Oh come ON, now. Ever heard of the "toilet-flush" effect? Where everybody makes a pit stop at the same time during commercials of a major televised event? Unlike your average office, where everyone has to constantly "give 110%", utilities run with reserve capacity and mechanisms that allow them to respond rapidly to sudden fluctuations in demand.

    Let's run that in reverse. A small increase in energy usage, like my one, 100 watt, bulb, won't increase the amount of energy pumped into the grid, so I shouldn't have to pay for it. (It's only 100 watts)

    Let's get everyone to do that! Free energy!! Perpetual Motion!!!

    Has anyone ever explained the difference between "almost zero" and "zero" to you?

    I don't know what current local rates are, but several years back, it was 17 cents a KWh in these parts. A 100-watt bulb is 1/10th of 1 kilowatt. Turning if off during Earth Hour would save you 1.7 cents at that rate. It may not be much, but it's still something.

    Turning off the A/C for one hour is only a net loss if the temperature shifts more than the amount it takes to recover an hour's outage. Otherwise, no post-Earth-Hour surge. Your MIleage May Vary, depending on climate and insulation.

    Turning off motors costs an additional amount of initial power surge when you turn them back on. How much, if any, that you save depends on the amount of power otherwise consumed during that hour less the surge.

    Turning off incandescent and fluorescent lights has relatively little surge turning them back on compared to what they'd eat for an hour. LEDs have effectively none. Then again, quite a few of my LED lights are solar-charged, so turning them off would be pure symbolism.

    Earth Hour is all symbolism anyway. Its prime function is to focus attention on what we're doing and what we might be doing. To THINK, not merely be a passive animal. We don't have to turn the world upside-down (yet, anyway). But we shouldn't just live in the here and now, we should consider where we want to be.

    In my younger days, I was cheap and would have just ordered the $35 board. Now I've got no patience and I ordered a case and USB power with the board. I've probably got a suitable-sized box in my general electronic junk collection and odds are that my phone charger can deliver the power, but we're talking less than $20 extra here for not having to find out otherwise.

    I'm saying there is no way of knowing if hunter gatherers had devised a way of making beer like beverages because they would have left no trace.

    Beer requires more work than wine or bread. Wine could be done with no lasting trace, but beer would be *impossible*. Why? Because there'd be some trace of tools or brewing. You "could" do it and leave no trace, but you'd have to go out of your way to do so, and unless you can come up with a plausible reason why a pottery-making society would use pottery for everything *except* brewing beer, then I'll invoke Occam and move on.

    The original version of the cauldron was a skin draped on sticks over a fire. It operates the same way as the more modern "boil water in a paper cup" trick. In fact, possibly the first pottery was an attempt to improve this idea by smearing clay on the skin.

    All sorts of nasty things have been cooked up at one time or another in a skin vessel, so why should beer be any different? But since skins usually rot, the odds of finding a "smoking gun" left behind by a group of wandering hunter-gatherers is pretty low.

    Sure you can tax into prosperity... Tax pays for services needed for prosperity, like security (police, defense), libraries, transport and communication infrastructure,
    education, a legal system etc at a minimum. This obviously doesn't mean that "more tax is always better", but some level of tax is needed. Providing care for the elderly and children increases the workforce and thus prosperity, but also requires funding.

    One of the clearest indications that political thought is an oxymoron is the idea that everything must come in only 2 flavors and nothing between, and that all lines must be straight lines.

    Reality isn't that tidy. There is a point where too little taxes fail society and a point where too much tax crushes. There's also a spot in between. Or actually, more of a blob, since there are a lot of variables in the equation. The blob can be larger or smaller or even inside-out depending on whether your demands exceed supply.

    We are the most spoiled generation in all human history. We have all - even the eldest - spent all, or nearly all of our lives expecting things to become cheaper every day. Sure, we howl about inflation, but the truth is, anything electronic has been chasing Moore's law for decades, and almost everything we do any more ties into something electronic, even if it's just just sitting down at the PC and figuring out when to plant the South 40.

    Matters only got worse when offshoring became economically viable. We've come to expect that Lower Prices Every Day is a right, and not simply being in the right place at the right time. No 16th-century farmer expected next year to require less effort or money to survive than last year.

    So we do foolish things like lower taxes right before a recession is due when we should have been saving the money for when the rains came and lowering taxes afterwards. And compound it, by fighting to keep the taxes low even as we embark on expensive campaigns.

    There's almost always something that isn't really necessary in any budget, whether it's personal, corporate, or government. And tough times help provide incentive for getting rid of it. Still, historically, we are used to being able to prosper while paying far more tax than we have for the last 10 years. And, frankly, the last 10 years have mostly been pretty miserable, so I don't buy the whole "lower taxes = more prosperity" line. If it can't work in a period that long, I'll likely die before it works at all - if it ever does. Ergo, it's useless for my purposes.

    The one thing that more government money can do that no one else can, is spend money when no one else dares to. Governments don't have to show a profit (and shouldn't!), nor do they have to be concerned over-much about daily expenses. They can keep on cranking regardless, and if it isn't very efficient, nonetheless, it keeps money in circulation instead of being hoarded. Hoarded money doesn't really do anyone any good.
