May the king be righteous,
May the people be […]

All life is based on the element carbon. Carbon is the major chemical constituent of most organic matter, from fossil fuels to the complex molecules (DNA and RNA) that control genetic reproduction in organisms. Yet by weight, carbon is not one of the most abundant elements within the Earth’s crust. In fact, the lithosphere is only 0.032% carbon by weight. In comparison, oxygen and silicon respectively make up 45.2% and 29.4% of the Earth’s surface rocks.

When will world oil production peak?
The energy field is littered with inaccurate forecasts of future oil supply. The best one can do is to describe a plausible range of values based on the prevailing range of credible estimates of how much oil remains to be discovered. My assessment of this research suggests the […]

Flying west across the continent, the traveler notices a dramatic change in the American landscape—from wet to dry, from green forests and cornfields to sagebrush plains and harsh deserts with only scattered stands of trees at the higher elevations.
