It is obvious that there is a need to green our residential and commercial properties. Carbon and CO2 emissions, oil and gas prices, and global warming ALL REQUIRE ACTION! Unfortunately, some greening ideas, that if implemented would save both monies and vital natural resources, are somewhat costly to install. True, it will pay for itself over time--- but there are upfront costs. LIPA still offers rebates of about 45% on solar system installations-- but the incentive used to be larger, and there were tax`credits that helped to subsidize the prices. We need a widespread use of alternative energy for both environmental as well as financial reasons!
