    All this rule changes is the efficiency for NEW wood burning stoves.

    Stop showing off. Just because you can understand what you read, doesn't mean everybody on Slashdot can. Either that or they're so knee jerk "damn gubmint regerlations" that they believe idiotic headlines like "EPA Makes Most Wood Stoves Illegal", when it should be something like "EPA Bans Sale of Dirty Wood Stoves". The horror! You can keep your old stove as long as you want. If you have to buy another one you'll pay little or nothing more for a wood stove that doesn't make your neighbors cough and choke. The horrors! What happened to freedom in America! (being constantly spied on by the NSA is a minor issue by comparison).

    New diesel engines, including for trucks (real trucks, not pickups) must meet pretty stringent emissions standards. Granted, for years they were essentially unregulated and it pissed me off that trucks, buses, constructions equipment, etc. could belch smoke and sulfur compounds while your car had to meet stringent emissions requirements, but that's a thing of the past. Why do you think all diesel fuel sold now has to be ULSD (ultra-low sulfur diesel). Of course you'll complain about the increased costs of ULSD, but according to the refiners it adds less than ten cents to the gallon.

    Yet another paragon of scientific insight. I've read more than enough of those denialist sites to understand the two basic strategies. First, find something stupid somebody said (today's example is Typhoon Haiyan), and act as if that debunks the whole theory. Meanwhile, back in reality, most climatologists are extremely vocal about the fact that no one weather event can be blamed on AGCC. The other approach is to cherry pick a few examples of noise defying an overall trend. It would only be suspicious if you couldn't find such examples. Any theory of something so complex that perfectly matched the data would be a fraud. Nowhere, of course, do the denialists offer a thorough statistical analysis of their own that refutes AGCC.

    The market is, by definition, far-sighted.

    By definition? The market is always right, if you define "right" to be whatever the market does. It's a tautology.

    The definition of a security's price is "the value of all future business of the concern."

    I hope you don't do any serious trading with that idea, because you're going to be very poor. As Keynes observed (from personal experience), the market can stay irrational longer than you can stay solvent.

    "balancing energy" (sorry, no dictionary has the right english term for "Regelenergie")

    Your English translation is close. We usually say "load balancing".

    Before germany had "solar power" we used coal. That means Switzerland is losing nothing due to our switch to solar and wind.

    No, unless the economic arrangements have changed recently, the Swiss now sell balancing energy at night, when prices are lowest and solar production is nonexistent. Obviously with solar you don't need to buy much balancing energy during the day. Because coal plants can the same output day or night, in the past the Swiss would mostly sell balancing energy during the day, when demand and prices are highest.

    I'm not saying that Germany is doing anything wrong, just that the Swiss are unhappy about it. I can imagine a time when Germany might need to pay them more so the Swiss are more willing to share load balancing with Germany, as opposed to finding other markets for Swiss electricity.

    Germany was dizzed by the US, for selling so many goods. I know that's because the industry fears ...

    Other European countries complain about that a lot more than the US, and for good reason. For all that I admire German industry in many ways, Germany has had a mercantilist policy for decades. The Plaza Accord in 1985 dramatically reduced the German-US trade imbalance because it forced Germany to stop manipulating its currency. More recently, the Euro is beloved by Germany because they can run a trade surplus which doesn't get balanced out by movement in the exchange rates. European financial difficulties would be far less without the Euro. Like most mercantilist countries, Germany prides itself on its thrift and the competitiveness of its industry, where the truth is that they're simply part of the problem. The US took a similar tact in the 1920's, and it was a big part of the reason for the Great Depression.

    A central power system is also a single point of failure

    No it isn't. The grid is many power stations tied together. There have been incidents where that interconnection itself has been a problem due to ripple effects of one power line failure (e.g. the Northeastern blackout of 2003), but that's technically solvable. As for local transmission line failures, the problem is poor practices (overhead lines instead of underground) and poor maintenance (e.g. lack of tree trimming near overhead lines). Most countries spend more on power line maintenance than the US, and it shows in the reliability. In other words, to the extent our central power station system is unreliable, it's because of penny pinching and politics, not technical barriers.

    distributed power generation is the way forward once they've got power storage sorted and cheap. The grid can be used as a back up system

    "Off the grid" is a pipe dream for most people. While household solar and batteries move towards that goal, the solar won't be enough to cover all power needs. That's especially true in, for example, apartment buildings. On the whole, greater use of renewables will require greater interconnection than what we have now. I applaud the German household solar approach, but Germany doesn't have anything like America's Southwest. A lot of solar can be generated there, but it takes long distance transmission lines to get it to people in less sunny climes. Similarly, the Midwest is an ideal place for wind power, but again you need transmission lines to get it elsewhere. These transmission lines are also important because of the unreliability of many forms of renewable power. It may not be windy in one place on a given day (or number of days), but it's rare for the wind to not be blowing everywhere. Hence you transmit the power to even things out. Hydro is another, and definitely the oldest case, of renewables requiring long distance transmission lines. The Pacific DC Intertie ships 3.1GW from Northwest hydro plants to SoCal. Much of the Northeast gets power from Hydro-Québec, which has 60 hydro plants generating an astounding 35.8GW.

    the loss of efficiency due to zillions of small power generation points more-or-less balances out with the gain in efficiency because the power is consumed near where it is generated, thus eliminating transmission losses

    Transmission losses for a traditional central power plant approach averages only 7%, from generator to electrical outlet. It simply is not a major source of inefficiency.

    Frankly, Germany would be better off selling excess electricity to the Swiss, who then pump their lakes full [wikipedia.org], and then buying that electricity back when needed. This is around 70% efficient, and a hell of a lot friendlier to the environment.

    There I agree with you. I defend batteries as not necessarily being the worst things, but hydro storage is better. Best is if you don't have to use pumped storage. You simply shut off (or at least cut back) hydro generation during the day and let the water build up in the reservoir, then use it at night or during unusually cloudy weather (a typical dam can hold a hell of a lot more than a day's worth of extra water, and certainly a much longer period's worth than any practical battery). You get better than 70% efficiency, and don't have to build pumps.

    AFAIK the problem is economics. The Swiss hate the German solar initiative, because it reduces the demand for their hydro power when the prices are highest during the day. Nighttime electricity prices are much lower. It would be nice if they could come to some sort of an economic agreement. It'd be worth it to the Germans to compensate the Swiss to some extent, because the Germans could save money on batteries.
