Indeed, All this nonsense spreading around is upsetting. YES, ofcourse there are disadvantages. So... Start using less power in order to minimise the negative effect. As somebody who has been living on solar power for over 20 years now, I can tell you that it is amazing how little power you actually need. E.g. neighbours have 2 fridges and a freezer. We survive with a small (camping-style) fridge/freezer. Do you need this huge plasma TV? Do you need to wash at 90 degrees C? We survive very comfortably with a 5kWh battery set which has been in service now for 6 years and not degrading because we take care.... Do you need this big SUV while a smaller car can do 5 liters/100km?? Or use excess solar/wind power for an electrical car? And then, when you have minimized your consumption, then select the source with minimum environmental impact and for the time being, that is solar/wind. Or sometimes hydro power.. But please stop this Facebook stuff and have a look at realistic cost/benefits. ALL costs and ALL benefits, not just slogans.
