    What are the pros/cons of these new renewable energy sources of fuel that are coming up nowadays?

    There's natural gas (methane) and ethanol. I've read that ethanol (E85) gas isn't that much cheaper than gas prices today, then why bother?

    So for the city of the future, what type of energy should fuel the way? which ones is taking shape to be a clear cut leader in cars, homes, etc?

    Geothermal, wind, solar.

    Cars, for better or worse, will go to hydrogen long term.

    For the short term, diesel-electric hybrid would have better well-to-wheel efficiency than anything else, but CARB and EPA can't seem to get their heads out of their asses long enough to realize they should be working with EU regulators to find compatible policies. Plugin hybrids should become more available whatever the fuel.

    The wider electricity grid will continue to be powered mostly by coal. Going forward, we'll see price-driven homeowner application of onsite wind and solar generation as well as passive geothermal for heating and cooling.

    There are new possibilities for deep geothermal drilling that would be widely exploitable and very clean.
