Alternatives to Fossil Fuels

I have a friend who's company specializes in alternative energy sources. He says the future lies in high efficiency turbine generators running on hydrogen. Where does the hydrogen comes from is still up for grabs (most people are thinking from reclaimed waste like sewage plants and garbage dumps.)
Personally I think that it lies in biodiesel. Biodiesel, if your plant can smell a bit like french fries, you can get banks of old diesel generators as a safer bet (and one that can be instituted today if you were so inclined).

I'd be leery of any claims for "Brown's gas," claims for which appear to be complete hokum.

Locally there has been a study on finding outcrops where fracturing has lead to the leaking of hydro-thermal fluid and altering of carbonate rich bed-rock. Usually limestone altered to form dolomite. One of the largest methane reservoirs ever found was a result of the above process and found in NYS just recently. I would just like to remark on a few other key notes. 75% of current power production in the US is through coal burning power plants. We estimate that we have enough coal to last approimately ~350years. Methane is another fossil fuel that is also rather abundant when compared to oil reservoirs. On the other hand, Nuclear power is the major power source for other countries like France. With the possibility of using recycled Uranium rods there is a high chance that in the near future we will see an increase in nuclear power production. Escpecially since the recent Yucca Mountain project being launched to house most of the spent Uranium not currently being recycled in the US.
