Re: Self sufficent energy
Oh god the hybrid thing again...
You really need to figure out your energy budget. The only way to do that is to figure out what equipment you will be using, how much you will be using it, and then add up the numbers. There are tools all over the Internet that will help you.
As for electric power to replace a diesel. Do a forum search, but generally no. You can't carry enough batteries to replace the diesel tanks, or anywhere close. If all you will ever do is drive off the dock, then you might be able to.
As for budget, 10-15,000 would be a minimum to seriously consider this, and that would require pretty spartan living in an area near the equator, with a minimal number of cloudy days.
