    we can do it if we all do our part.

    •  Some seemingly obvious questions: (7+ / 0-)

      Why are the new electric cars not all equipped with built-in solar panels on their skyward facing surfaces -- at least as an option? "Charge as you drive...", absolutely minimizing carbon-based electrical charging.

      Why are new buildings not all required to have solar panels on their roofs? Especially in the sun-drenched areas of the country, like the southwest. (Of course, the answer is cost... But this should be heavily subsidized!)

      Imagine a country where everyone was driving a Leaf or a Tesla or any of the new models coming down the line, with charging stations everywhere and panels on cars, and all buildings were energy efficient and energy generating. Wow.

      Of course, this will only happen over the Koch Bros cold dead bodies.

      The only entitlement that needs reforming is the inbred belief of the 0.1% that they are entitled to 99.9% of the wealth and 100% of the power.

      •  flitedoc, car-roof panels not practical (6+ / 0-)

        The orientation (horizontal) is awful, and with the extra weight, you would be lucky to break even.

        PV panels belong on the garage roof, not the car roof. :-)

        But yes, in a better world, PV panel evaluation would be required for all new construction, and installation required where the evaluation checks out.

        Lots of legal obstacles there, but as we know, the future existence of human civilization depends on us getting CO2 out of the atmosphere...

          Well, the light ones would more than break even. Sure, they're not very efficient, but they are REALLY light. 250 grams for a 10-watt 11% efficient panel in current production. (And that 10 watts is assuming naive placement in direct sunlight... so, as you say, 'horizontal'. And one of them would fit nicely on top of a car if built in... maybe even two, if you used the hood and back as well.)

          However, I admit that, even if this is much better than break-even, it still isn't going to get you very far. (This would charge the Chevy Volt's battery in, uh, let's see... 1600 hours? Of direct sunlight? So, say, 300 days in a good climate?)
