Living off the grid does not mean that one has to live painfully rustic. Yurts can be customized with insulation liners, awnings and doors with windows among other additions. Most additions add to a yurt's energy efficiency and to one's overall comfort.
For example, with an optional dome, one can add a ceiling fan to keep cool in the summer. Of course, the fan can be powered by solar energy or by wind energy. It is an enticing picture: Visualize no utility bills, living green--away from the madding crowd.
