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

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

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.

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

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

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

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

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.

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

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.

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

You can lose your way groping among the shadows of the past.

Anxiety and conscience are a powerful pair of dynamos. Between them, they have ensured that I shall work hard, but they cannot ensure that one shall work at anything worthwhile.

There are some decision-makers in the world whose version of sanity is a little different from what I consider the right one.

Luck ran out, but smart was for life.

A lot of animal experiments consider only commercial interests. We want to ban all animal experiments as soon as possible.

When scattered clouds are resting on the bosoms of hills, it seems as if one might climb into the heavenly region, earth being so intermixed with sky, and gradually transformed into it.

I sometimes miss the days where I could fly a little more under the radar. There was no social media in the '90s, and it was a different world. I also miss TRL - that was always a blast!

I really believe amendment " to make English our common and unifying language" is racist. I think it's directed basically to people who speak Spanish.

I certainly don't sit around in the morning making pancakes listening to Whitehouse or anything.

The momentary thrill of getting rarely equals the lasting joy of giving.
