All renewables, much as I love them, are diffuse. They all have a small power per unit area, and we have to live with that fact.
The United States consumes power per land-area at a rate three times the average. Even though they are more energy efficient, densely populated industrial countries like Germany, Britain and Japan have even bigger power consumption per area.
There's a limit to how much you can deploy renewables, like wind or solar. People will talk about getting up to 30 percent of America's power from renewables, but you can't get to 100 percent because of their unreliability.
A country becomes more prosperous in proportion to the rise in the invested capital unit per unit of its population.
It's important to understand that oil and renewables do different things. Wind and solar are for power generation, so they don't replace oil. About 70% of all oil produced is used for transportation fuel. Renewables are good projects, but they don't get us off of foreign oil.
You know most people live ninety per cent in the past, seven per cent in the present, and that only leaves them three per cent for the future.
I think the driving force for cultural evolution is this desire for groups to be splitting off and separating and forming subgroups insofar as the environment will allow it. We see great cultural diversity and large numbers of cultures per unit area in regions of the world in which the environment is really rich.
I like that I can write my name in Persian, and it's a small unit, like a graphical unit. I feel the same way about my name in English, it's a graphical unit.
Young women, the family unit is forever, and you should do everything in your power to strengthen that unit.
I think the likelihood that combustion will continue to represent the large portion of the power unit world is very small.
If you have a native monetization system where the atomic unit of content is the ad unit, that scales down all the way to a small screen experience. That's why Twitter is performing so well on mobile.
With transparency in renewables, the prices of renewables are coming down drastically.
Once you've lived in Del Mar or the San Diego area, why would you want to live anyplace else? It's the neatest place, whether it's the culture or the small-town atmosphere the whole San Diego area has.
I am a Christian person, and I do love the Lord, and I feel no matter who you are, what you believe, how you live your life, it's not my place to judge. I don't have that power. I don't want that power. It's my place to love and to show God's love to other people, even if they don't live a life like I live.
[The Persian Empire] left a dream of the Middle East as a unit, and a unit where people of different faiths could live together.
I am happy with the way I hit the ball. There is a certain element of power into it but not completely. It is like 80 per cent timing and 20 per cent power. Why do I need power hitting when I can clear the ropes with timing?
Egypt does not possess rich natural resources. Its agricultural area is relatively small - less than 10 per cent of the total land. Its growth relies on tourism, Suez Canal tariffs, and foreign investment.
