Liveaboard life: self-sufficient w/ solar, sails & VHF radio

When Teresa Carey is sailing she knows just where all her energy comes from and where it's going. She has just a 130 watt solar panel - about 30 times less wattage than the average household- so she keeps electronics to a minimum. Besides solar and her sails, she uses some non-renewable energy: diesel for a small engine and propane for her stove.
