The world must prepare for the transition to Previous HitrenewableNext Hit non-polluting Previous HitenergyNext Hit sources to ensure the continuous flow of Previous HitenergyNext Hit to the world ’s increasing population and expanding economies.World oil supply will meet demand until the peak plateau of world oil production is reached which is estimated to be between the years of 2010 and 2030. Ultimate oil recovery will range from a conservative 2700 GBO (billion barrels oil)or an optimistic 3640 GBO (billion barrels oil). Declining production after peak oil production occurs will cause a global Previous HitenergyNext Hit gap to develop because Previous HitenergyNext Hit demand will continue to grow. This Previous HitenergyNext Hit gap can be avoided by forward planning. Previous HitEnergyNext Hit conservation, improved Previous HitenergyNext Hit efficiency, expanded production of unconventional oil and conversion of natural gas to liquids will help extend the time of peak oil production. The long-term solution to Previous HitenergyNext Hit supply is conversion to Previous HitrenewableNext Hit, non-polluting Previous HitenergyTop sources, which include, solar, nuclear, hydroelectric, geothermal, wind, biomass and hydrogen. Solar, nuclear and hydrogen should become major power source in the 21st century.
