I believe that the burning up of Earth's fossil fuel resources just as quickly as possible is not a good idea.  I would like to include AGW as another reason to conserve but the AGW conjecture has many major flaws.  The AGW conjecture depends upon the existance of a radiant greenhouse effect attributed to the heat trapping effects of some trace gases with LWIR absorption bands.  The reality is that such a radiant greenhouse effect has not been observed anywhere in th solar system including the Earth.  As derived from first principals, the surface of the Earth is on average 33 degrees C warmer than it would be otherwise because of a convective greenhouse effect caused by gravity, the heat capacity of the atmosphere and the depth of the troposphere.  33 degrees C is the amount of warming derived from first principals and 33 degrees C is what has been observed.  Any additional warming caused by a radiant greenhouse effect has not been observed.  The AGW conjecture is science fiction.
