Well, if you decide you want to use a lot of electricity, you send me a check for twice as much money as you spend on electricity. I will then send you a certificate assuring you that I will consider investing your money in companies that are developing “alternative” fuel sources.
The theory is that if you and enough others do this, I will become very wealthy and you will be able to sleep better at night knowing that you’ve done your part to save the planet.
I think I can work with that for voucher credits. All may freepmail me for the PO Box to which the orders may be sent. These voucher credits are real useful.
