I can not remember how long I have been hearing about solar power, but I know that it has been at least for 20 years of more. You would think with all the time that has gone by and all the research that by now more people would be on board. I find it hard to believe though that we are just now really getting great green advice and the country is starting to pay attention to the limited resources that we have been using. Solar power is a great way to save on these resources so that many generations to come will be successful.
