The 15-20% loss in transmission is more than offset by the economy of scale
available to the large producers. This goes for fossil fuel based utilities as
well as renewable energy producers.
No, living off the grid does not produce "multiple energy sources" in the sense
of "multiple choices" for individuals. When you put up your wind turbine and
solar cells, are you going to offer the electricity for sale to your neighbors?
No, it is more likely that you will size your system just big enough to meet
your own needs. You won't have any excess capacity to sell to anyone, certainly
not with the reliability of the current commercial producers. And you won't
have a means to transport that electricity, now that you have done away with the
grid. Without the grid, there is no marketplace for electricity at all.
And what you are still ignoring is the fact that most people cannot afford to
live off the grid.

Your question is unclear because you don't specify "better than what?" For the
people I am speaking about (which is the majority of the American population),
there is no other choice. They do not have a spare $0,000 to spend on a 5kW
wind turbine or solar cell array. So the grid is better than nothing, which is
what they would have if they didn't have the grid.
So let me put the question back to you. Propose a complete scenario in which
there is no electrical power grid and in which resources are utilized "better".
And if you can do it without killing off 90% of the population first, then you
get bonus points.

Of course it is. Consider the economics of all residents of a town or
city going off-grid. The only place off-grid makes economic sense is
where the costs for connection to the grid are prohibitive.

OK point taken
Well what abt a hybrid method whereby you are on the
grid but also have your own generating capability tied
to the grid as well?
Again a serious question
