If you haven't seen it before this is a good video addressing many of the important issues relating to building a human society on Mars (many of the sort that Elon Musk tends to brush over):

For Louis re #1
Thank you for providing the link to the YouTube video. I found the format, involving blog comment posters, to be interesting for its variety.
Efficiency of energy usage ought to be a major concern for Mars dwellers, for a considerable period of time, if not for ever.
The quote below is taken from one of the newsletters I receive periodically. The reference is available upon request. Since the source is a proprietary organization I don't want to clutter this forum.
DC Data Centers: A Necessary Paradigm Shift for Sustainability and Savings
Vast amounts of electricity are wasted in data centers, lost to tedious, continuous, and ultimately unnecessary conversion and transformation processes. Switching the prevailing AC power supply to DC would prevent much of this energy loss, but it requires a massive paradigm shift.

Its the compound conversions that are the problem as the loss for each will add up when changing from ac to dc and so forth as many times as we are doing it. With the solar output being DC this is just one of those conversions that you can not get back. We still use high voltage battery dc to transimit power in parts of the power grid.
With Musk promoting batteries for all of the devices that are related to power storage and outputing the fact that he is making the largest battery comes as not really a surprise to be used.
