I originally had two small solar panels I purchased from an 'Energy Sciences' advert in the back of a Mother Earth News Magazine...about 1980/81...I'd fussed around with a 6 volt windcharger back in the mid 70s...and with these panels, it was a real 'wow' moment. When I built my current home, no mailbox, no phone, no electric...no bills...a postal box in town...those two panels and a large truck battery gave me a light in my bedroom, a light in the kitchen and a light in the 'living' room...a 12volt JVC combo SW/AM/FM dual cassette recorder/player and record player...and a 9 inch 12 volt tv...which gave me three channels...rambo, dumbo and bimbo...18 bucks a year for my property taxes, a root cellar/pantry for refrigeration...no meat unless it was killed that day...(an occasional rabbit/grouse/woodchuck/squirrel)... It was very freeing... My wants grew as my income grew, over time...many people mention to us how green we live...but, thinking back to those times...I really lived green, with a much smaller footprint... Can't turn back the clock, but I remember and kick myself back into shape every now and again. We've become much more spoiled over time. I remember thinking...not what I was doing without...but the luxury of what I had...no bills/no ties...no 9 to 5... Conservation is the key...and quelling our desires. I'm in the process of using more efficient products...such as LED lights...but, they are products, which means...they had to be produced...and there are ramifications in the production of anything. I think I'm lecturing myself as much as posting about conservation and solar energy.
