The key difference is that energy use by plants is biological, while most energy use by humans is mechanical/electrical/themal/whathaveyou. In fact, in the case of ICEs, tends to increase w/ power output, not decrease. Otoh, as was described plants have a tradeoff between energy efficiency and power, so to speak. In case you didn't notice, engines, motors, and all sorts of other stuff that we use most of our energy w/ are not the same as plants.
All of our mechanical energy comes from plants in the form of fossil fuels that are the result of decaying plant matter under perfect conditions.
We are simply harvesting ancient plants every time we fire up an ICE.
Ultimately, virtually all of our energy is solar energy of one form or another. What is problematic is that we have had the benefit of millions of years of STORED solar energy in the form of fossil fuels. Once that stored energy is used up, what do you replace it with? As far as I know, there are no other similar stores of energy on our planet. _________________

That's what I told the board of directors. However, the name already existed from their old website. _________________ A Saudi saying, "My father rode a camel. I drive a car. My son flies a jet-plane. His son will ride a camel."
