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.

If a war started, the oil price probably would go up, as you said, maybe $5, $6 a barrel until you saw other oil from the extra supplies that are available elsewhere coming into the world, into the market.

The starting point for energy security today as it has always been is diversification of supplies and sources.

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

This has a lot to do with the unrest in Nigeria, but also with the production loss after the hurricanes in the Gulf of Mexico, the decline in Iraq since the 2003 war, and the decline in Venezuelan output since 2002.

A premium in the oil price of somewhere between 10 to 15 dollars a barrel reflects this heightened anxiety.

The North Sea was supposed to run out in the 1980s. Then in the 1990s. And now production is still on-line.

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

We are living in a new age of energy supply anxiety.

I think the producers, for the most part, don't want to see prices skyrocket because that will only create problems for them down the road and would also be a, you know, would be a very serious shock for a world economy that can't afford serious shocks right now.

We are living in a different world now. You can see it everywhere in international relations: It was noteworthy that, after his visit to Washington, the Chinese president's next stop was Saudi Arabia.

It's extraordinary how inventive one can be with ethanol right now.

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.

Clearly, the Chinese need the resources, but I don't think they want to clash with the industrial world which happens to be the market for their goods.

So the major obstacle to the development of new supplies is not geology but what happens above ground: international affairs, politics, investment and technology.

First, we have to find a common vocabulary for energy security. This notion has a radically different meaning for different people. For Americans it is a geopolitical question. For the Europeans right now it is very much focused on the dependence on imported natural gas.

The Russians are turning east to the Chinese - to the Europeans' surprise. It always seemed to me that the relationship between Russia and China would shift from being based in Marx and Lenin to being based in oil and gas.

The bulk of extra supplies that could be put into the market come from two places. One, they come from other Persian Gulf suppliers, of which Saudi Arabia is at the top of the list.

The other are the strategic, so-called strategic stocks that the United States and the other Western industrial countries have, which could put in as much as four million barrels a day of oil into the market pretty quickly.

But the key thing is that Iraq, while it's got very large oil reserves, has marginalized itself as an oil exporter and these days its exports are only about one tenth that of neighboring Saudi Arabia.

We experienced similiar fears in the 1880s, at the end of World War I and II. And we ran out in the 1970s.

In a couple of years, the Chinese will be seen as regular participants in international industry. Their companies have to report to shareholders as well as to the Chinese authorities. They need to make money, they have to be efficient.

People always underestimate the impact of technology. To give you an example: In the 1970s the frontier for offshore development was 200 meters, today it is 4,000 meters.

But eventually it's a question of access: Getting access to fields is on top of the oil companies' agenda. We see a substantial build-up of supply occurring over the coming years.

We experienced similar fears in the 1880s, at the end of World War I and II. And we ran out in the 1970s.

If you give it good concentration, good energy, good heart and good performance, the song will play you.

We need to have a culture that says 'the less energy you can use to be comfortable, the better off you are and the better you should feel about yourself'.

I merely took the energy it takes to pout and wrote some blues.

I didn't know at the time that the energy that I was giving off was like a battle Emcee.

The young people look great on television. They're youthful and have a lot of zip and energy, but when you see them live, they can only do about 20 minutes because they haven't got the training to hold an audience for an hour and a half or so.

It takes a lot more energy to fail than to succeed, since it takes a lot of concentrated energy to hold on to beliefs that don't work.

I try to give positive energy in all my shows.

In modelling, there is no point in trying to prove you have a brain, so why even bother? I'd sooner save the energy for something more meaningful.

I was part of it, and I am still part of it today in terms of what it means to a whole new generation of people who are interested in the enduring energy, achievements, spirit and creativity that exemplified our era.

I always like having kid energy around. I think it's good for a movie, even when you're doing dramatic stuff.

You had to decompress the pressure before the race. I taught my heart to relax. I lay down before the race. It gave me more energy just before the race.

As long as I had easy access to psychedelics at the government-sponsored research project, most of my energy went into psychedelic sessions.

You can have anything you want if you want it desperately enough. You must want it with an inner exuberance that erupts through the skin and joins the energy that created the world.

Nerves provide me with energy... It's when I don't have them, when I feel at ease, that's when I get worried.

Electric cars aren't pollution-free; they have to get their energy from somewhere.

When I see someone who is starved, they don't look alert. They don't have boundless energy. If you're too skinny, it looks like you're near death.

Why is it so painful to watch a person sink? Because there is something unnatural in it, for nature demands personal progress, evolution, and every backward step means wasted energy.

Comedy is so hard; it's so much harder than drama. The pacing of it, the energy of it.

If for no other reason than the energy crisis now facing this country, the federal government should be eager to become partners with us in rebuilding our city.

It takes a lot of energy to teach.

Any long work in which poetry is persistent, be it epic or drama or narrative, is really a succession of separate poetic experiences governed into a related whole by an energy distinct from that which evoked them.

I believe that the average guy in the street will give up a great deal, if he really understands the cost of not giving it up. In fact, we may find that, while we're drastically cutting our energy consumption, we're actually raising our standard of living.

Life must be considered sui generis; it is not a form of energy, nor can it be expressed in terms of something else.

Men find it difficult because I've got so much energy and hardly sleep at night, only four or five hours. I wake up in the early hours and potter around.
