If solar water heaters, or electric panels would work on your house, would you spend the money to install them, if they would pay for themselves over their lifetime?

Why do manufacturers of things like clothes washers & dishwashers have “done” lights that can’t be turned off on their appliances?
Do you need to see the time displayed on your TV, VCR, Cd changer, etc, etc, etc?

Do you reuse as much as you can? Do you recycle what you can’t reuse?

Really, there’s a LOT that can be done, now.
