The peak oil crisis: technology update

by

All this new technology seems to say there may be some hope for life after oil. For now the two biggies seem to be cold fusion and cheap hydrogen, but neither of these are as yet sure for the immediate future. It seems likely we are going to have much more efficient motor vehicle within the next 10 years and probably longer range electric vehicles. There might even be enough biofuels to run our airplanes.

The Way is Shut

by

When I first approached the topic of societal energy in 2004, I became aware for the first time that our energy future was not in the bag, and proceeded to explore alternative after alternative to judge the viability and potential pitfalls of various options. I have retraced my steps in Do the Math posts, exposing the scales at which different energy sources might contribute, and the practical complexities involved. My spooky campfire version of the story, a la Tolkien: The Way is Shut.

En busca de un milagro: Los límites de la ‘energía neta’ y el destino de la sociedad industrial

El informe explora alguno de los escenarios de transición de energía propuestos actualmente, mostrando por qué, hasta el momento, la mayoría son demasiado optimistas, ya que no tienen en cuenta todos los factores relevantes que limitan la expansión de fuentes energéticas alternativas.This is a Spanish translation of the Post Carbon Institute and International Forum on Globalization and report ‘Searching for a Miracle’.

World energy consumption – beyond 500 exajoules

by

Today’s post goes into the global consumption of energy and provides a dataset in Excel for researchers on global primary energy consumption from 1830 to 2010. We are now burning 10 times as much energy as a century ago to provide the goods and services we consume. Energy consumption is still increasing rapidly

 

Review: The KunstlerCast by Duncan Crary

by

Outrageous, snarky, “madly engaging,” bileful—these are a few of the terms that have been used to describe author and social critic James Howard Kunstler. But he’s actually a great deal more than these things, as anyone who’s really come to know him, even if only through his books and Internet postings, can tell you. His most personal writings reveal a human, vulnerable, wonderfully versatile, cheerful side that few people know exists.

The alternative energy matrix

by

Breathe, Neo. I’ve been running a marathon lately to cover all the major players that may provide viable alternatives to fossil fuels this century. Even though I have not exhausted all possibilities, or covered each topic exhaustively, I am exhausted. So in this post, I will provide a recap of all the schemes discussed thus far, in matrix form. Then Do the Math will shift its focus to more of the “what next” part of the message.

From mountain to sea: A vision for the rebuilding of Tohoku

by

Why would a fisher care about the forest? The person to ask is Shigeatsu Hatakeyama, an oyster farmer from Kesennuma in Japan’s Miyagi Prefecture. We can learn a great deal from Hatakeyama. He is one of those rare types of people who can see beyond the day-to-day preoccupation of how to make a living — in his case, with an oyster farm — and instead embrace the world around them.

Nuclear Fusion

by

Ah, fusion. Long promised, both on Do the Math and in real life, fusion is regarded as the ultimate power source—the holy grail—the “arrival” of the human species. Talk of fusion conjures visions of green fields and rainbows and bunny rabbits–and a unicorn too, I hear. But I strike too harsh a tone in my jest. Fusion is indeed a stunningly potent source of energy that falls firmly on the reality side of the science fiction divide—unlike unicorns. Indeed, fusion has been achieved (sub break-even) in the lab, and in the deadliest of bombs. On the flip side, fusion has been actively pursued as the heir-apparent of nuclear fission for over 60 years. We are still decades away from realizing the dream, causing many to wonder exactly what kind of “dream” this is.
