Having just been through 3 days with no power after Hurricane Matthew I have been thinking more about these alternative forms of power. I grew up with many people using wind for their water supply and know that it is still common in some areas. As a source of electricity it has problems, but the availability of more efficient lighting, refrigeration, and power storage have made it more usable. Solar power also has limitations. I know that remote sites often use these systems, and I have seen many boats with such power sources. Any experience? I know that these sources can actually save money in the long run.
