    The government doesn't inflict anything on you for having "too much power". It's the utility company, a private company who doesn't want you generating your own power because that directly eats away at their profits!

    I have read their feeble excuses just a few months ago when they sent me a letter telling me why they are keeping all the money. They said that they do so "due to the state law." What they didn't mention is that they purchased that law.

    You can read about AB 920 here, for example. Prior to that bill the utility owned the excess power outright. The bill is an improvement, but it contains specific language that allows utilities to continue pocketing energy that is generated locally. If I produce excess 3 kW and my neighbor needs 3 kW then the utility is not even involved ... but they are earning money on that transaction.

    But this seems somewhat fair as the utility needs to pay for maintenance of your share of the distribution grid

    I pay for that as a separate line item on the bill. It is about $15/mo. They don't charge per kWh that I consume, so they shouldn't do that when I produce.

    The only way to get the utility companies to do anything different is to get your representatives to write laws to force them to change.

    They did that already. To change the law I need to send more money to Sacramento than PG&E did. I'm not that rich.

    It's the utility company, a private company who doesn't want you generating your own power because that directly eats away at their profits!

    Well, that brings us back to my original conclusion. What is it that we, as the society, want - to have PV or not to have PV?

    The main issue is the cost to produce those panels which is dropping quite rapidly - quite a bit more rapidly than expected thanks to massive amounts of silicon manufacturing capacity which has come online in the last 2 years - which is also what led to Solyndra's demise yet made them look promising 4 years ago

    Solyndra failed because their efficiency/price ratio was not good enough to compete. If they had 100% efficient panels then they could charge quite a lot of money for them, and people would be gladly paying.

    Some say that it also illustrated lack of competitiveness of US-based industries. Solyndra's employees were all living as kings, compared to Chinese workers - but by local standards they were only paid enough to live. A small apartment in SV will cost you $1,500/mo but the same living arrangements in China may be far cheaper (not everywhere, of course.)

    And you probably have room to double the size of your PV array - but the cost currently keeps you from doing that.

    Yes, I have lots of room on the hillside, I could have installed 10x more. But not only there is no government incentive for me to do that, there is a PUNISHMENT that the government inflicts upon me for having "too much power."

    The punishment is that when you consume energy you are paying retail rates, they are high. When however the electrons go in the opposite direction the rules of the game suddenly change, and you are paid at power plant rates - which are far lower. In essence, if you have overproduction of energy by the end of the year you might just as well forget about any revenue from it.

    Generators are paying less because that money covers their costs and reasonable profit. The utility charges more because it needs to cover their own costs (the grid) and reasonable profits. As a generator, I am indeed using the grid to deliver the power, so I can understand where they are coming from. However the larger objective of the society - to promote installation of solar panels by every household - suffers terribly because the homeowner is disincentivized to buy larger solar panels in hope of serving his neighbors. Good deeds will always be punished!

    So, who benefits from this pay structure? The generator does not really care at this time, they are counting in gigawatts. The PV system owner loses. The utility gains. Yes, if you buy large solar panels then you put your money in pockets of the electric company. They get energy right at the point of consumption, and they get it at dirt cheap rates! No need to incur losses by transporting it over thousands of miles; no need to sign long-term contracts. They have the PV system owner over the barrel on this. Want to make the future green? Fix that, make the prices the same in both directions. The fee for using the grid is actually listed separately on the bill, and PV owners pay it every month regardless of how much they produce. That should remain. But the cost of pure energy should be equal, to consume and to produce. Otherwise if I overproduce it will take me 75 to 100 years to break even - and the PV system is only expected to work for 25 years. In other words it will never be profitable. The government should either put up or shut up.

    You lack imagination. Energy is energy. More solar energy pours down on the planet in a few hours than humans use in a whole year. We didn't get as far as we have by sticking with the old ways of doing things.

    I have some imagination - I need it for work, I'm an engineer working with electronics. Yes, we have lots of energy - and we can't capture it. Without capturing energy efficiently we can't use it. Solar and wind are enormously expensive; solar is also very poisonous, since manufacturing of pure silicon requires lots of nasty chemicals.

    You should not discount economics. For example, you are taking a bus to school every day. But starting tomorrow someone way above you and me decided that buses are polluting and you should walk or use your bicycle. The only problem is (for example) that you have only one leg and you can't do any of the above at any reasonable efficiency level. You can't spend a week to crawl to the school. You don't have money to pay someone to carry you there, unless you stop eating. What are your choices? This is the problem that invariably occurs when the cart is placed in front of the horse.

    The same problem exists everywhere else. Imagine that starting tomorrow coal and gas plants stop making energy. Cost of energy goes through the roof. As result you can't cook food at home! What are your options? Making a fire on the kitchen floor with your philosophy books?

    I'm glad that you know of a coal power plant that is more expensive - for whatever reason - than solar. (I have 6 kW of solar panels at my house, by the way.) However failures of solar power are far more common, even despite huge injections of public money into those projects (see Solyndra.) The reason for that is simply that solar panels today are not very efficient. Will they become better? Probably, over time. Maybe even soon. But today we can capture very little of the energy that is coming down.

    You need to consider also the weather. Not every region is suitable for solar power. Not every region is suitable for wind either. The energy is out there, but it's very costly to mine it. I have sun here, but wind is either 0 (for most of the year) or 60 mph for a few days in winter; in both cases the windmill would have to be shut down; it would be completely useless to me.

    In the end, a hungry man needs his daily food. You cannot tell him that he should eat only every other day - even though food is available - because food on odd days is "unclean." But that's what green advocates are doing. The goal is good since I can't imagine an advanced society of Star Trek type that burns coal to power its spaceships. But we cannot implement the program until the program becomes viable. We cannot destroy the world in order to save it.

    I'm not against nuclear power but it's an awful expensive way to produce electricity and the lead times are so long. I'm not sure it will be able to compete with solar and wind in another decade.

    Nuclear power is very competitive with these sources right now. We do not need to guess what will be 10 or 20 years in the future. Today's nuclear reactors by that time will be ready for decommissioning, and then we can decide what to do, and we will have all the up to date information. Guessing today is pointless. What is not pointless is running all the reactors that you got. Each operating reactor prevents burning of a mountain of coal!

    I would understand if UN, for example, or some other worldwide organization, set up a research institute that would focus on the new energy sources, collection and storage methods. But that's not what happened. Instead we have con men like Al Gore that are cutting coupons from useless "carbon credit" trade. Essentially, rich countries are supposed to pay money to poor countries because those poor countries don't pollute that much. Please tell me how this helps develop new technologies?

    Yes, and here is why.

    The best weapon is the one that is so powerful that you don't even need to use it. A threat alone is sufficient to achieve your goals. However an ICBM is not suitable for that.

    For example, NK wants to respond to a threat. However a launch of an ICBM is a guaranteed suicide on national scale (South Korea will not get out of it alive.) It doesn't matter if that ICBM carries a nuke or a dummy payload; it doesn't matter if that ICBM manages to get onto the trajectory or if it fails over Japan and falls into the ocean. None of that matters. If you launch (against any nuclear country) you should expect immediate response.

    NK, however, wants negotiations and political gains. Politics is called "art of the possible." Politicians deal not with accomplished facts but with "what would you do if I do this?" NK needs a threat that is not immediate but that can be activated on short notice. And that threat must be real and there must be no defense against it. A nuclear mine (or several,) planted somewhere on the territory of the opposing country, will do the job just fine.

    Also, you are mentioning the 1/10K chance of failure if the delivery is done via normal shipping. However what would you expect the chance of failure of an ICBM be? An ICBM that was never tested for the true distance; an ICBM that probably exists in quantity one; an ICBM designed by people who had more failures than successes; an ICBM made in a tiny pariah country that is under all sorts of embargo? I'd say their chance of failure would be 1/2 if not 1. And that is before the missile shield does anything. In other words, an ICBM threat from NK is not believable; it's on the scale of a threat that some natives on some faraway island pose by praying to their local gods to smite $whoever. But if NK goes ahead and launches then it will be destroyed. Pretty useless as a negotiation tool, I'd say.

    Additionally, why do you think the chance of discovery is 1/10K? It can be made very low by carefully hiding parts. I can think of many ways to do it. Perhaps I shouldn't mention any of them, but they are pretty obvious to anyone who just stops for a moment, turns the TV off and thinks. To intercept, you'd need to know for a fact that a specific shipment contains a specific item. This knowledge can't be gained if even the shipper is unaware. Besides, there are 37,000 ways to bypass ports and customs; NK has mini-subs that can be delivered into US coastal waters on (or under) a ship and then dropped off. A mini-sub can then hide in the noise of screws of some large ship, or in its acoustic reflection, and get to the shore completely undetected. All that can be done at NK's leisure, slowly and carefully, with as many dry runs as they want. And once the device is delivered it will be lost for good - until it is activated.

Europe is not interested in wars. India and Pakistan are focused on each other. However the USA habitually wages wars and throws its weight around; in part that's necessary to sustain the dying economy and falling dollar and the armies of unemployed. Therefore sharing the early warning data would be useless. Russia would need some sufficient control over interceptor sites to be sure that they are not targeting Russian launch sites. But NATO would want to cover Russia as well, even though it is not very effective. The danger here is that what is not sufficiently effective for a general might be sufficiently effective for an ignorant, half-crazy President (like John McCain, for example.) US voters are perfectly capable of electing such a person.

    The latest talk is that Obama gives Russia the specs on interceptors (as if Russia doesn't have them already, which I presume.) I do not believe there will be any agreement unless Russia can know for a fact that its territory is not covered by the shield, one way or another. The need for that is caused by existence of WMD in all involved countries. If we look at the history, the Mad Fuehrer rose to absolute power in Germany within about a decade. The same unfortunate event can, theoretically, happen in any nuclear country - and therefore MAD has to remain for now, to keep such a budding dictator of the world in check.

    If a country refuses the pressure then it can be given some punishment - for example, some unimportant village can be mysteriously destroyed, and an errant warplane of the victim country would be blamed. The politicians will then be privately told that if they don't behave then the same happens to their own cities. What can they do?
