The Alliance for Wise Energy Decisions (AWED) is an informal coalition of individuals and organizations interested in improving national, state, and local energy & environmental policies. Our basic position is that technical matters like these should be addressed by using Real Science.

Instead of a science-based approach, our energy and environmental policies are typically written by those who stand to economically or politically profit from them. As a result, anything genuinely science-based in these policies is usually inadvertent and accidental.

A key element of AWED’s efforts is public education. To this end, every three weeks or so a newsletter is put together to balance what is found in the mainstream media about energy and environmental matters. We very much appreciate MasterResource for its assistance in publishing this information (for the two most recent reports, see here and here).…

“Power density (W/m²) is perhaps the most revealing variable in energetics…”[1]- Vaclav Smil

It may be a bit of an exaggeration to say that understanding power density may be all the average person requires to put our energy sources and needs into perspective, but there is some merit in this argument. Unfortunately, this view of energy matters remains little discussed, probably because it appears rather academic.

This post attempts to overcome this by further illustrating the concepts. It will also demonstrate how industrial-scale wind and solar PV electricity generation plants fail to meet this important, high-level standard of performance for electricity sources required by mankind, particularly in developed societies, but increasingly in developing and even undeveloped societies.

This is even without taking into account:

(1) The persistent erratic (short term – minutes) and unreliable (medium to long term – hours to days) nature of electricity production that wind and solar PV provide; (2) their high costs; and (3) many other considerations described here.

“I might add a prediction—that the hydrocarbon energy age could still be young, even quite young. The much-hyped emergence of a new renewable energy era by mid-century is less our energy future than our energy past…”

I am honored to receive the [2002] Julian Simon award tonight. My thanks go to the Simon family and the Competitive Enterprise Institute for having this annual award to recognize and encourage new contributions in the “sustainable development” field that Simon pioneered.

My appreciation also goes out to a number of groups within the classical liberal “structure of production” that have supported my intellectual development over the last quarter century, and in particular the Institute for Humane Studies at George Mason University, the Cato Institute, and the Atlas Economic Research Foundation.

Julian Simon was very interested in energy and energy-environmental issues.…

“PURPA has been the most effective single measure in promoting renewable energy.”

–Union of Concerned Scientists

What if Congress passed a law that forced you to buy intermittent energy for the same price as reliable energy? What if, in an attempt to promote “alternative” energy sources such as wind power, Congress passed a law that enabled wind to crowd out reliable resources? Congress actually passed that law in 1978, the Public Utility Regulatory Policies Act (PURPA). Its role has changed and its scope has narrowed, but “PURPA is still alive and kicking.”

Background

President Jimmy Carter, working from the viewpoint that the federal government had to intervene in markets to reduce demand and increase supply, formulated PURPA as part of a five-part National Energy Plan.

Oil and gas were seen as wasting resources relative to plentiful coal, so public policy needed to transfer demand from the former to the latter.…
