To meet the energy challenge requires the most important energy of all - human creativity. That's the real prize.

Cycles of shortage and surplus characterize the entire history of oil.

But that's not enough: To maintain energy security, one needs a supply system that provides a buffer against shocks. It needs large, flexible markets. And it's important to acknowledge the fact that the entire energy supply chain needs to be protected.

Even Silicon Valley investors have put well over a $1 billion in new energy technologies.

In a world of increasing interdependence, energy security will depend much on how countries manage their relations with one another. That is why energy security will be one of the main challenges of foreign policy in the years ahead. Oil and gas have always been political commodities.

In the mid-1980s, operating problems took [nuclear] plants off-line so often that, on an annual basis, they operated at only about 55 percent of their rated total generating capacity. Today, as a result of several decades of experience and an intense focus on performance ... nuclear plants in the United States operate at over 90 percent of capacity. That improvement in operating efficiently is so significant in its impact that it can almost be seen as a new source in electric power itself.

The world has produced about 1 trillion barrels of oil since the start of the industry in the nineteenth century. Currently, it is thought that there are at least 5 trillion barrels of petroleum resources, of which 1.4 trillion is sufficiently developed and technically and economically accessible.
