    Well now that is a problem.

    Problems with solar and wind, besides the money angle, still exist. Hopefully they can work on those problems but they may never fully replace petroleum. I read recently where some geothermal plants were incurring problems with deep drilling around hot spots, such as increased earthquake activity at the site. Still better than the big promise of Nuclear power in my opinion, as the latest Fukushima reports of a newly discovered leak would seem to indicate.

    Alternate sources are fine for generating electricity but fossil fuels will be needed for the majority of transportation needs. Much work is still needed for batteries. PBS Nova did a piece on batteries a couple days ago.

    Fossil fuels are also used in manufacturing most everything.

    That won't change anytime soon, either.

    What happens to "everything" produced if you burn remaining stocks in transport?

    Good question. One day, burning petroleum might be seen as burning good building lumber for fuel.

    Lots of petro fuel will be replaced by electrical energy.

    Already happening, in fact.

    I don't see commercial airliners powered by batteries anytime soon, though.

In fact, I think all of that is taken into consideration when the structure is designed....)

    SOLAR panels of all sizes, can go....EVERYWHERE (at least, every where you do not wish to "shade" with the panels themselves). Roofs, on the sides of Highways/interstates, on the SIDE of many buildings, Auto Rooftops, etc.)

    Geothermal seems like a great idea, and I can't think of any limitations, other than cost, and PERHAPS that some ground soils may not be fitting for what ever reason (ie, would it work in Southern California? On the one hand, you probably have GREATER energy sources under Southern Cal, but, due to so many Earthquakes (many of them very small), I am wondering if the ground, itself would not 'cut' many of the geothermal ports...???

    But, what we REALLY need, are not better ways to HARNESS energy, but, to STORE it, and send it through the GRID. This is where we lose an immense amount of power.....
    The turbines could be installed on top of buildings where the wind is great. It is feasible, just needs investments.

    Our companies have become short term. They need more long term.
