text: which techonologies/resources will be prevelent in the next 20 years to lower our need for oil?   bio fuels...such as corn, and vegetation to reduce our dependencies...  coal, it can be made into oil...expensive process, but with the cost, they finally got it to where they want it, so a new industry is about to take over now.  trees being made into oil then gas...it will decay into some form of fuel, or biodegraded with chemical compounds to do so.  solar isnt energy efficient yet, because the fuel cells are too heavy and the solar value isnt up there as always available yet.  wind power for home and solar power for homes.  streams and other natural water ways for electricity.  plus there are many more ways, but these are a start...  i wish you well..  jesse
