Not really.
Bottom line is there is no free lunch.
Every replacement KWH of power you generate consumes energy and has a
cost.
The fact that you are converting fuel into motive power for instance,
does not eliminate the fact that you are also converting fuel into
electrical energy at the same time.
What many people also overlook is the fact that a storage battery is a
very inefficient device.
You must replace 125 AH for every 100 AH consumed.
It's not magic, it's just the nature of the beast.
