Clean Tech Open Gala Awards

The author, Robert Rapier, presents specific calculations on the comparative costs between natural gas and oil.  Natural gas is a bargain at $4 per million (MM) BTU to oil's current $12.24/MMBTU.  Also note that this is at $71 a barrel, not the $100 plus price we saw for oil last summer.  So why doesn't everyone just convert?... read more
