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

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.

But the age of chivalry is gone. That of sophisters, economists, and calculators has succeeded; and the glory of Europe is extinguished forever.

I grew up with art from the innocent age of ten - with art, but with no sense of identity.

Death comes not to the living soul, nor age to the loving heart.

I'm very pleased to be here. Let's face it, at my age I'm very pleased to be anywhere.

For example, UNICEF works with governments to change legislation such as in India where a law was passed raising the age of compulsory school completion to keep children in school and away from the workplace for longer.

I figured out it was a social thing, what women were allowed to do. At a very young age, I decided I was not going to follow women's rules.

I wish I knew at 14 not to put much thought into what other people my age said to me, cause we were all looking for the answers. So I wish I knew that other people really don't know any more than you do!

I believe very firmly that gay people of every stripe and age should be role models for all children, and that means interacting with them.

Donner likes what he does and enjoys being on a set. He doesn't have to do it, its not like he has to make the rent. When I get to be his age and still enjoy what I'm doing like him, I'd be lucky.

Does age matter? Time doesn't matter.

I realised from a very early age that God gave me a gift, and that gift was to run, and I wanted to use it to the best of my ability.

Looking back, I think we were all quite mature, surprisingly responsible. In earlier wars, boys of our age had just gone off to raise hell or enlist or both, but we stayed dutifully at our desks doing tomorrow's homework.

This is the patent age of new inventions for killing bodies, and for saving souls. All propagated with the best intentions.

Interest is the spur of the people, but glory that of great souls. Invention is the talent of youth, and judgment of age.

For me, having a child is a really great responsibility because you've got something there that is depending on you for information and love until a certain age when it goes to school.

I don't think at my age... you can start ruling people out in politics.

I figured my body always would be able to repair itself. I think all of us believe that - until you begin to age and get hit with deteriorating joints.

Another principle is, the deepest affections of our hearts gather around some human form in which are incarnated the living thoughts and ideas of the passing age.

I read. It's also nice for me to get involved in schoolwork, which is a totally different world than acting. It makes me feel like I am doing things that normal people are doing at my age.

When you're my age and you see a story, you better go for it pretty quickly. I'd just like to get a few more novels under my belt.

Hollywood is sexist and age-ist, and that covers all the bases, I guess.

Middle age is the awkward period when Father Time starts catching up with Mother Nature.

America doesn't reward people of my age, either in day-to-day life or for their performances.

When you get to a certain age, the work begins to thin out.
