Economic/Environmental Assessment of Grid-Tied Photovoltaics: Arizona Lessons for the U.S.

The proponents of the Arizona Renewable Energy Standards (RES) make various claims in order to promote grid-tied solar photovoltaic (PV) electricity. Unfortunately, the use of grid-tied solar PV is unlikely to accomplish any of the objectives suggested by its proponents. Specifically, 

  • It will not create jobs in Arizona;
  • It will not reduce global warming;
  • It will not reduce electricity prices;
  • It will not reduce our dependence on imported oil; and
  • It will not position Arizona to be a leader in renewable energy.

Furthermore, there is a good chance that the RES will have outcomes that are directly opposite its intended effects.…

Power Density Primer: Understanding the Spatial Dimension of the Unfolding Transition to Renewable Electricity Generation (Part II – Coal- and Wood-Fired Electricity Generation)

By Vaclav Smil -- May 10, 2010 2 Comments

Editor’s note: This is Part II of a five part series that provides an essential basis for the understanding of energy transitions and use. The opening post on definitions was yesterday.

Baseline calculations for modern electricity generation reflect the most important mode of the U.S. electricity generation, coal combustion in modern large coal-fired stations, which produced nearly 45% of the total in 2009. As there is no such thing as a standard coal-fired station I will calculate two very realistic but substantially different densities resulting from disparities in coal quality, fuel delivery and power plant operation. The highest power density would be associated with a large (in this example I will assume installed generating capacity of 1 GWe) mine-mouth power plant (supplied by high-capacity conveyors or short-haul trucking directly from the mine and not requiring any coal-storage yard), burning sub-bituminous coal (energy density of 20 GJ/t, ash content less than 5%, sulfur content below 0.5%), sited in a proximity of a major river (able to use once-through cooling and hence without any large cooling towers) that would operate with a high capacity factor (80%) and with a high conversion efficiency (38%).…

Climate Model Magic: Washington Post Today, Gerald North Yesterday (Part IV in a series)

By Robert Bradley Jr. -- April 13, 2010 20 Comments

[The other parts of this series on the activism of Texas A&M climatologists are here: Part I, Part II, and Part III]

“If the models are as flawed as critics say … you have to ask yourself, ‘How come they work?'”

– Gavin Schmidt [NASA], quoted in David Fahrenhold, “Scientists’ Use of Computer Models to Predict Climate Change is Under Attack,Washington Post, April 6, 2010.

“We do not know much about modeling climate. It is as though we are modeling a human being. Models are in position at last to tell us the creature has two arms and two legs, but we are being asked to cure cancer.”

     – Gerald North (Texas A&M) to Rob Bradley (Enron), November 12, 1999

A Washington Post piece last week, “Scientists’ use of computer models to predict climate change is under attack,” has brought attention to the importance of climate modeling in the current debate over climate sensitivity to greenhouse gases (GHGs).…

Howlin’ Wolf: Paul Ehrlich on Energy (Part II: Failed Predictions)

By Robert Bradley Jr. -- March 20, 2010 11 Comments

[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.”…
