A Conversation About Energy with Howard Lindzon

by

A few weeks ago, I had the opportunity to do a freewheeling, videotaped chat with StockTwits founder Howard Lindzon on the present and future realities of energy…Topics included peak oil, the end of economic growth, reversing globalization, oil prices, alternatives, and lots of other topics.

Energy concentration revisited

by

The difference between diffuse and concentrated energy sources, the theme of last week’s Archdruid Report post, means that some of today’s highly touted alternative energy schemes may be worth much less than currently claimed, while other technologies that receive much less attention may be the wave of the future. A closer consideration of energy concentration and its effects helps clarify which is which.

Ecosystem Modeling

by

An ecosystem is no more nor less than the sum of individual responses of diverse cooperating or competing organisms to stimuli from events in their environment. Diversity is a sign that there is a high number of stimuli and that the system has become dynamic in response. A great many small parts, making separate and nimble adjustments, solve problems better than a few large parts responding ponderously.

Americans Increasingly Unworried About the Environment

by

People grasp what their drinking water has to do with them. Overwhelmingly, I think they do not fully grasp what global warming has to do with them – and that’s a rhetorical failure…At the same time that highly effective movements are arranging million person demonstrations in the streets, most of the people who will actually tell their congressfolk whether to vote for change were watching Law and Order SVU.

Post Carbon Exchange #1: Richard Heinberg & Lester Brown (transcript added)

by

In this premier Post Carbon Exchange, Post Carbon Institute Senior Fellow Richard Heinberg talks with Lester Brown, Founder of the Earth Policy Institute, about hopeful developments in alternative energy, as well as the importance of Brown’s updated path toward a sustainable future, “Plan B 4.0”.

What is the Minimum EROI that a Sustainable Society Must Have? Part 1: Surplus Energy and Biological Evolution

by

EROI theory is rooted in the biological principle that in order to survive each species on earth must procure more energy from its food than it expends attaining that food. From this basic principle the importance of energy surplus became evident, as food sources needed to “pay” not only for metabolism but also for reproduction and storage for leaner times. Part 1 of this three part series presents a brief history of the concept of surplus energy and how it has influenced both biological and human evolution.

The curious return of coaldung fuelballs

by

While in the hills of western India last week I saw something I haven’t seen since my schooldays. The something is old-fashioned fuel balls. You can hold one of these lightweight balls in your hand, for they are around 8-9 cm in diameter, their colour a slatey grey flecked with brown. You only rarely see them being sold in the small provision shops in these villages, for the fuel balls are made at home. They require two ingredients: cow dung and coal dust.

World crude oil production may peak a decade earlier than some predict

by

In a finding that may speed efforts to conserve oil and intensify the search for alternative fuel sources, scientists in Kuwait predict that world conventional crude oil production will peak in 2014 — almost a decade earlier than some other predictions. Their study is in ACS’ Energy & Fuels, a bi-monthly journal.
