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. Towards that end, every 3 weeks we put together a newsletter to balance what is found in the mainstream media about energy and environmental matters. We appreciate MasterResource for their assistance in publishing this information.

“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.
