“In this century the bulk of humanity will live in large densely populated cities. If the citizens of of these cities are to attain a high quality of life they will require large centralised energy generation. This is not a matter of ideological preference, but of engineering reality.”

– Robert Wilson, The Future of Energy: Why Power Density Matters, Energy Collective, August 8, 2013.

“There is no doubt that we in the United States need to alter our energy strategy. The question is how we will change it. A rational energy strategy must be determined by scientific evaluation of fact and logical analysis of performance and economics–not by emotion, political considerations, and ‘feel good’ methodologies.”

– Jerry Graf (below)

Other than the damage to the economy from the waste itself, the real problem with mandating and subsidizing non-viable energy technology projects is that this distracts us and diverts resources from other efforts to improve our energy production strategy.…

“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.

For well-being, present and future, including overall governance, health and medical care, financial, economic, human rights, equality, peace, security and liberty, etc.,[1] we have to stop playing political games with energy policy in the developed countries in the West and turn to sound approaches.

In particular, Europe must withdraw from its desperate and destructive attempts at regaining some measure of world ‘leadership’, which it deservedly lost in the 20th century as a result of succumbing to dangerous extremist policies in many areas, including political, social, judicial, economic, military and international matters.

Europe’s “leadership” conceit includes questionable, radical energy policies, particularly in electricity systems, to “de-carbonize” the world with “new” (really ancient) renewables. This futility is wasting resources on a grand scale as is now beginning to be realized (here and here).…

In a 2009 speech before the United Nations, Israeli Prime Minister Benjamin Netanyahu spoke about hope for the future:

“It took us centuries to get from the printing press to the telephone, decades to get from the telephone to the personal computer, and only a few years to get from the personal computer to the internet. What seemed impossible a few years ago is already outdated, and we can scarcely fathom the changes that are yet to come.…
