Jimmy Carter and the energy crisis of the 1970s: the "Crisis of confidence" speech of July 15, 1979 : a brief history with documents[edited by] Daniel Horowitz; Bedford/St. Martin's 2005WorldCatLibraryThingGoogle BooksBookFinder 

With the exception of preventing war, this is the greatest challenge our country will face during our lifetimes. The energy crisis has not yet overwhelmed us, but it will if we do not act quickly.

It is a problem we will not solve in the next few years, and it is likely to get progressively worse through the rest of this century.

We must not be selfish or timid if we hope to have a decent world for our children and grandchildren.

We simply must balance our demand for energy with our rapidly shrinking resources. By acting now, we can control our future instead of letting the future control us.
