Thinking outside my wallet isn't easy for someone who is retired and on a limited income or for a young person trying to keep their head above water. You need to read my post again, Lowell if you think I am not doing more than most to help the environment. (I said I do not have gas in my area for the water heaters.) In the winter I keep my house at about 50*. How hot do you keep yours? Are you running an AC all summer long to keep your house cool? I learned to adapt..... One correction to my post: The world population will top nine billion until the baby boomer generation (my generation) reaches their life expectency. Harsh results need harsh demands.
