I am sure that many of you are familiar with the Rocky Mountain Institute founded by Hunter Lovins and Amory B. Lovins.
They tackle the tough questions and they prove to those that will listen that IT SAVES MONEY TO CONSERVE. I like these guys because they are clearly correct and they work to make things happen by eliminating obstacles.
The issues they tackle are the big ones. If you have some time then study their very good website. I personally believe that they think this stuff through and they have gotten to the heart of the problems.
