    If you want to influence the direction of a company, you would want to own as much of its stock as possible, not get rid of it. If you are extremely wealthy, you can just buy all of the company's shares and have total control over its direction.

    Bingo. A 'responsible' party owning 10% of Exxon could be the difference between Exxon having executives who are mustache-twirling villains and having a responsible board that has the company investing heavily into renewable technology to position itself for the inevitable decline of oil.

    Oil isn't just used for fuel, it's a lubricant.

    If we're not using it as a fuel, there's plenty of organic sources that can rather easily provide for our lubrication needs. Thermal depolymerization, for example, generates what's effectively an extremely pure light sweet crude. The processes used to make synthetic oils don't need to use fossil oil as a feedstock.

    It's a bit like worrying about people getting enough drinking water when they're living in a city in the desert and thus dying of thirst. It's not the people we have to worry about so much - drinking is near the bottom of the list for municipal water. You use more washing hands. Obtaining enough water for people to keep their clothes washed is a much bigger problem in such a case. Drinking water is such a small usage that we could truck it in if we had to.

    We don't have to. Let's say we pass a few reforms. Things like house the homeless($10k annually vs $40k to leave them on the street), reform sentences and prisons(1/2 the prison sentence AND less likely to come back?), and healthcare. The fed.gov already spends 90% of what it would take to provide single-payer UHC if we were paying the median for industrialized nations. The individual states more than pick up the remaining 10%. We currently spend ~$6.7k vs $2.9k. So fixing this ONE problem would enable states to put more money towards other important things without going into debt, help with the federal deficit, AND dump about a grand more into every family's pocket a month.

    What does $3k a year, per person, pay for? A hell of a lot of solar panels and other sources of renewable power. We can improve our lives in a lot of other ways.

    When you are on an island with no coal, oil or gas and consumption is so low that you have to use small and inefficeint generators then it doesn't take much of a price drop for solar to be cheaper.

    Hawaii does have a coal plant, but they have to ship the coal in, and they are big enough for the generators to be efficient, even though it doesn't leave much slack.

    and probably would have imported some geothermal technology from NZ, Iceland or wherever a couple of decades ago.

    If it was cheaper I would have expected them to do it just to improve their bottom line. Seems that they have one in Puna. Of course, it also mentions that the largest/most populated island, Oahu, isn't a good candidate for geothermal power. To the point that they're considering stringing a power cable undersea to connect the islands in order to transfer power between them, exploiting Big Island's geothermal plant for Oahu's benefit.

    As for Alaska, hell no, save the oil for heating and selling down south. We have coal up here as well, we're currently in the process of trying to restart a coal power plant - it's even a 'clean coal' one that was built with the assistance of federal subsidies for the purpose of research.

    Finally, I swear I've had a conversation similar to this before about Hawaii - Sure it's a special case, but that makes it a good candidate to look at for the potential problems the mainland could face if solar installs explode.

    Anything over 20% of power from solar means we start getting close to cutting into power production by base load power plants. Much above that and you'd see night power costing more than daytime. If we get much above 30% we'd need some massive storage banks to actually use the power efficiently.

    Besides, on average, solar power users produce power during the day, when demand is high and the cost of production is relatively high (because peaker plants are expensive).

    That's currently true, but look at Hawaii - they're quickly reaching the point where they'll need their peakers more at night than during the day. They're quickly reaching the point where some of their distribution circuits will occasionally go negative during the day.

    Net metering only works when you are indeed on average selling expensive electricity for the same rate you're buying cheap electricity. If more than 20% or so homes and businesses install solar panels the equation flips - now nighttime power is more expensive than daytime.

    Sorry for not actually creating a template, but it'd be more along the lines of attacking somebody for having a liberal arts degree - not a science or engineering degree to indicate that you've been trained in how to assess the dangers of mining/drilling in an area. Revealing that they're getting money, or at least have ties with, people that the target audience don't like and don't think should have a say in their business. Example would be Bloomberg's 'donations' to help spread gun control in the USA. It's often counterproductive because, well, the gunnies* hate him so bad. The Koch brothers would be the ones from the opposite side of the fence. They seem to like donating to 'any' conservative republican running against a liberal democrat in a competitive campaign. They don't really care where.

Fact is, we need resources to power our economy, and if you give the impression that you oppose EVERYTHING(and there are people who do), or your plan amounts to powering the economy on fairy farts, perhaps your efforts to constrict expansion should be restricted.

    I say all of this as an anti-coal, pro-nuclear type. I think that the republicans have a point about the EPA - every regulation needs to be examined thoroughly, but consider diesel vehicles. Do you realize that because of the latest round of emission requirements, mileage in new diesels has dropped 20-30%**? We're talking about stuff like new hybrid buses getting worse gas mileage than their older non-hybrid cousins. The city can't afford to run the new buses in long routes because they don't save fuel. They WERE saving fuel until a new EPA approved engine was put in...

    Anyways, to get back to the point - a single person 'rolling coal' with a deliberately modified truck in protest of the EPA's rules negates the benefits of the systems they mandated on about a thousand other trucks(and yes, those that do so are assholes). Personally, I think that the EPA needs to place stronger emphasis on retaining gas mileage, because we need to conserve oil. At this point the EPA is increasing fuel consumption and CO2 emissions for reducing other emissions - and I don't think that it's worth it.

    *Given his staunch support for gun control and the fact that while Mayor of NYC he attempted to increase gun control on a GLOBAL scale, often donating money to gun control initiatives in individual states across the country I can see why.
    **At least until you rip out the extra EPA stuff or reprogram the chip. Then you get the gas mileage back Details on modifications necessary depend on vehicle and emission system.
