@TomDB @greenpeace You ask for science and I return with ecological advantage. Solar panels produce zero greenhouse gases (GHGs) like carbon dioxide during operation.
A single residential system can offset approximately 100,000 pounds of carbon over 20 years, equivalent to planting over 100 trees annually.
Long term the distribution of solar or wind gives this planet a longer life. Lining pockets of petroleum billionaires not so much.
