how do you read a potential enregy diagram?

Okay, cool!\nThe diagram is set up so that on the horizontal x-axis is the "reaction coordinate," which is basically just time as the reaction proceeds.  The vertical y-axis is energy.  \n\nThe potential energy of the reactants is where the graph curve starts, touching the y-axis.  The potential energy value is the y-value at this location.  \n\nWhere the graph curve levels off at the end is the products, so the potential energy of the products is the y-value where the curve levels off.  \n\nThe activation energy is how much energy had to be added into the system to get to the activated complex, located at the peak of the diagram's curve.  Take the y-value at the top of the curve and subtract from the the potential energy of the reactants.  \n\nThe heat of reaction is the difference in the potential energies of the products and reactants.  Take the potential energy of the products, and subtract from that the energy of the reactants.  \n\nIf a catalyst were added, the potential energy of the products and reactants remain unchanged, but the activation energy is less, so you draw a curve that starts in the same place and ends in the same place as the original diagram, but your curve just won't go up as high.  The hill for a catalyst is less steep.

How do I look at it from here?

Your fuel cannot be considered to be efficient or inefficient.  Only the process via which the energy is extracted from it.  The equation for efficiency is as follows:\n\nefficiency = 100*(Useful energy out)/(Energy in)\n\nThe units are Joules for the energy and the efficiency is given as a percentage.  For energy in you would put how much potential energy the fuel contained and for useful energy out you would put how much of the potential energy was converted to a useful form (for example a power station converts the chemical potential energy in coal into electrical energy).\n\nFor example 1kg of a certain fuel may contain 100kJ of chemical potential energy.  If you now have a generator that converts this chemical potential energy into 50kJ of electrical energy and 50kJ of heat energy (wasted energy in this case).  You would say that the generator is 50% efficient as half of the chemical potential energy the fuel had was converted into a useful form.

Definitions of potential energy on the Web:\n\n    * The energy stored in a raised object (eg the weights in a grandfather clock). Potential energy equals mgh, where m is mass, g is the acceleration of gravity, and h is the vertical distance from a reference location. It is called potential energy because the energy can be regained when the object is lowered. This type of potential energy is sometimes called gravitational potential energy in order to distinguish it from elastic potential energy: see elastic energy.\n      http://urban.arch.virginia.edu/~km6e/references/glossary/struc-glossary.html\n\n    * energy stored in an object due to its position\n      http://whyfiles.larc.nasa.gov/text/kids/Problem_Board/problems/pulleys/glossary.html\n\n    * The energy which a body possesses as a consequence of it's position in the field of gravity, the work required to bring the body up against gravity from a standard level.\n      http://cimss.ssec.wisc.edu/oakfield/keyterms.htm\n\n    * Energy related to the position or height above a place to which fluid could possibly flow.\n      http://www.flw.com/define_p.htm\n\n    * The energy that matter has because of its position or because of the arrangement of atoms or parts.\n      http://www.nmlites.org/standards/science/glossary_4.htm\n\n    * Potential energy is the energy possessed by an object because of its height above the ground. The amount of potential energy possessed by an object depends on its mass and its height. A roller coaster car is initially hauled by a motor and chain system to the top of a tall hill, giving it a large quantity of potential energy.\n      http://www.learner.org/exhibits/parkphysics/glossary.html

I haven't checked to be sure, but theres a site called 'howstuffworks.com' I believe, and it has diagrams and breakdowns of just about anything. Check it out.
