Dan,
Essential points is a judgment call. Agreeing or disagreeing with the article and what points it may make is also a judgment.
What you might call essential points may not match what I call an essential point, not to mention that what someone would characterize as an essential point can be determined by how the article influenced or failed to influence the reader.
I believe many got the point that it is possible (not a fact, merely possible) that the hybrid vehicle may not be the most energy efficient choice from dust to dust.
However, many, like myself, took exception with the "accounting" aspects of it, and this weakened the credibiity and usefulness of the article, changing what I find are the essential points.
I didn't need a study to tell me that for me to buy an already produced used car uses less energy than buying a brand new car, shipped from the factory.
From my point of entry into the lifecycle of the car (which is really all that matters to me, an essential point to me
) the energy used to design, build, deliver, drive and maintain the vehicle prior to my ownership really doesn't matter.
So I don't know if I got an A, a C, or failed the "test."
What I do know is that my answers, so far, have been working for me in the real life, pass fail exam called life.
