Most analyses and reviews of utility-scale, highly intermittent new renewables, especially wind power which will be the focus here, are lacking in perspective. This makes marginal aspects appear to have significance out of proportion to the very little value they represent.

A few examples are:

· A focus on the energy contribution (MWh) from wind power leads to error in assessing the contribution to electricity costs, reliability, impact on fossil fuel consumption and CO₂ emissions, transmission needs and the operation of an electricity system.

· The possibility of some improvements in wind forecasting. Given the current state of weather forecasting in general, it seems difficult to believe that wind can be forecast for short time intervals, say 24 hours in advance. In any event, even if such forecasting was possible, it does not change the need for balancing generation plants to be ramped frequently to mirror wind conditions.

Synopsis: The U.S. Environmental Protection Agency, by pulling its punches in the Massachusetts v. EPA Supreme Court case, granting California a waiver to regulate greenhouse gas emissions from motor vehicles, and declaring greenhouse gas emissions a danger to public health and welfare, has positioned itself to regulate fuel economy, set climate and energy policy for the nation, and amend the Clean Air Act – powers never delegated to EPA by Congress. It is time to rein in this rogue agency. The Congressional Review Act Resolution of Disapproval introduced by Sen. Lisa Murkowski (R-AK) is the way to do it.

When did Congress tell the U.S. Environmental Protection Agency (EPA) to license California and other states to adopt non-federal fuel economy standards within their borders? When did Congress tell EPA to act as co-equal or even senior partner with the National Highway Traffic Safety Administration (NHTSA) in setting fuel-economy standards for the auto industry?…

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.”…
