Rare earths refer to some 17 elements found in Earth’s crust by themselves or combined with other chemicals. Some are scarce and others abundant, but in most every case Rare earths create risk in the renewable energy supply chain under an “energy security” standard.

The metals and their compounds used in battery technologies, windmills, catalysts, and communications technologies are not mined in the U.S. The majority of commercially useful Rare earths come from mines in China, a country that is fickle toward the U.S. in many ways. This energy-security issue contradicts a rationale for taxpayer support for government-dependent energy technologies such as windpower and electric cars.

China’s Rare Earth Monopoly

The Rare earths occupy 57th to 71st place on the periodic chart of the elements. Discovered largely in the 19th century, the minerals have proven useful for modern technologies because of their electrochemical properties.…

Editor note: Part I examined Dr. Ehrlich’s views on Julian Simon, growing energy usage, and depletion. Part II examined his errant energy forecasts. (Previous posts on the worldview and statements of Obama science advisor John Holdren are here.)

Energy conservation(ism) was the Ehrlichs’ silver bullet for fossil-fuel depletion. Current usage levels were decried as enormously wasteful. Depletion and climate change called for “a reorganization of the American way of life” to cut energy usage in half or else “the nation would go bankrupt.” [1] The bankruptcy would come after “frequent unpredictable blackouts and brownouts, the continual need to devise more ‘emergency’ measures, and the return of closed gasoline stations.” [2]

Transportation Usage

On the transportation side, smaller cars, alternative vehicles (even with “miserable pickup”), “slower coast-to-coast transportation,” and an end to two-car families were recommended as, potentially, “the cost of survival.”…

[Editor’s note: Part I in this five-part series examined Dr. Ehrlich’s views on Julian Simon, growing energy usage, and depletion. Part III examines Ehrlich’s conservation(ism) views.]

The Ehrlichs’ angst about the energy future was rife with forecasts that have been proven false–and embarrassingly so. As mentioned in Part I, the Ehrlichs’ protégé John Holdren has made similar radical pronouncements and wild exaggerations (see here and here) and even joined Stephen Schneider and other climate scientists in the global cooling scare.

Running Out of Oil

Writing in 1974, the Ehrlichs predicted that “we can be reasonably sure . . . that within the next quarter of a century mankind will be looking elsewhere than in oil wells for its main source of energy.” [1] Consequently, “we can also be reasonably sure that the search for alternatives will be a frantic one.”…

Scientists find themselves fighting science when it comes to the highly unsettled physical basis of climate change. An example of this is the March 7th Houston Chronicle op-ed by two Texas A&M climate scientists (and four colleagues from other universities), “On Global Warming, the Science is Solid.”

I took general exception to their piece in Part I in this series, titled “Andrew Dessler and Gerald North on Climategate, Climate Alarmism, and the State of Texas’s Challenge to the U.S. EPA’s Endangerment Finding.” Chip Knappenberger yesterday took issue with their claim that the Texas Petition was flawed because it “contains very little science.”…
