The Path from Petroleum Shortages to Electricity Shortages

It seems to me that there is likely to be a very short path from petroleum shortages to electricity shortages. There are a lot of issues involved, from the fact that the fuels used in electricity production are themselves dependent on petroleum for their extraction and transportation, to the current state of the US electricity infrastructure, to the impact of peak oil on debt financing. I have written about most of these issues before, but since the petroleum/electricity link is such an important one, I thought I would devote an article to putting the pieces together.

Fuels used for electricity generation

In the United States, the primary fuel used for electricity generation is coal, at 49% of electricity production. Natural gas follows at 22%; nuclear at 19%; hydroelectric at 6%, and petroleum at 1.6%. The newer renewables are all quite small: wood at 0.93%; wind at .77%; waste at .41%; and solar (for electricity generation) at 0.01%.

What Future for Coal in South Africa?

This is a guest article by Jeremy Wakeford. Jeremy is an economist specializing in energy and sustainable development and is Research Director of ASPO South Africa.

South Africa has been in the news a lot recently because of its electricity supply problems throughout 2008. Most South African electricity comes from coal-fired power stations. Jeremy discusses the role of coal in South Africa's energy mix, long-term trends in production and consumption, and how underground coal gasification might help solve South Africa's energy problems.

"Energy Resources and Our Future" - Speech by Admiral Hyman Rickover in 1957

M. King Hubbert made his views about peak oil known in 1956, at a meeting of the American Petroleum Institute. Many people don't know that only a year later, in 1957, Admiral Hyman Rickover started trying to publicize the fact that fossil fuels are finite, and were likely to peak in the first half of the 21st century. Many of the things he said then are words we wish people had listened to years ago:

Fossil fuels resemble capital in the bank. A prudent and responsible parent will use his capital sparingly in order to pass on to his children as much as possible of his inheritance. A selfish and irresponsible parent will squander it in riotous living and care not one whit how his offspring will fare.

Today the automobile is the most uneconomical user of energy. Its efficiency is 5% compared with 23% for the Diesel-electric railway. It is the most ravenous devourer of fossil fuels, accounting for over half of the total oil consumption in this country.

I suggest that this is a good time to think soberly about our responsibilities to our descendants--those who will ring out the Fossil Fuel Age.

Peak Oil and the Financial Markets: A Forecast for 2008--July 31 Update

Back in January, I made a financial forecast for 2008. In this post, I will update my analysis, looking both at what has happened thus far in 2008, and refining what is likely ahead.

Most forecasts are made with an overriding assumption of infinite growth, but the analysis made in January and updated now maintains an underlying assumption of resource limitations, such as will likely accompany the advent of peak oil. Under resource limitations, debtors are likely to find it difficult to pay back loans, as resources become more and more scarce. As a result, default rates are likely to continue to rise.

One of the issues I consider important in my forecast is systemic risk. This relates to the interconnectedness of the system, and predicts that if one part fails, other parts are also likely to fail. Many other articles mention this issue, but rarely address its full ramifications.

Lester addresses U.S. governors on energy future, calls for Marshall Plan for energy innovation

This is a transcript of a speech by Richard K. Lester, MIT professor of nuclear science and engineering and director of the Industrial Performance Center, who spoke on 14 JUL 2008 at the annual meeting of the National Governors Association. The prepared version of Lester's speech is below the fold.

Lester is a co-author of recent MIT reports on the future of nuclear energy and coal energy, and he has published widely on the management and control of nuclear technology. He is currently leading the Energy Innovation Pathways Project, an interdisciplinary MIT assessment of the capabilities of the U.S. energy innovation system.

I found the speech interesting, so I thought I would bring it to you. A quote that particularly caught my eye is the following: "And so, to conclude, it is long past time for serious federal leadership on energy innovation. But it is also time to move beyond the Manhattan/Apollo Project metaphor. A better metaphor might be a domestic Marshall Plan for energy innovation. The original Manhattan project involved a relatively small number of people working in secret. The original Marshall Plan took everyone, working together, to rebuild the broken European economy."

Has Fossil Fuel Consumption Within the EU Peaked?

The title will hopefully make some readers choke on their coffee and spill the remains in their cup all over their computer(s).

A Pretty Stunning Graph of World Cement Production (and China is Certainly Using It)

Annual production of cement by country in billions of metric tons. Click to expand. Source: USGS 2006 report (PDF) and the USGS 2008 report (PDF).

Cement is mainly used to make concrete, and is sort of the "active ingredient" in concrete - it is combined with sand and gravel in roughly fixed proportions. So cement production can be considered a rough proxy for the total amount of construction going on in a country.

This post updates Stuart's post about this two years ago (and yes, it's still a graph that will blow you away!) with two more years of USGS cement data, 2006 and 2007. The growth in China, from 1 GT to 1.3 GT in two years is mindboggling, even India and Russia are interesting...and there's more to think about under the fold.

edited to add: As a couple of folks pointed out--I have interchanged "production" and "usage" in this post incorrectly--however, China's 2007 cement exports were only 33 million tons out of 1.3 billion tons produced. So, at least for China, production is a good proxy for demand/consumption. My apologies for the mistake.

A Little History of the Affordability of Domestic Energy in Great Britain

This is a Guest Post by Bob Everett. Bob is Lecturer in Renewable Energy at the Open University in Milton Keynes, UK.


Domestic energy is getting expensive, but what does that mean compared to the situation in our parents' or grandparents' days? Should we grumble?

Richard Heinberg: Coal in the United States

This is a post by Richard Heinberg, Senior Fellow of The Post Carbon Institute and author of Peak Everything, The Party's Over: Oil, War and the Fate of Industrial Societies, Powerdown: Options and Actions for a Post-Carbon World, and The Oil Depletion Protocol. A special thanks to Global Public Media for facilitating publication of Heinberg's work; GPM is a wonderful resource and plays an important role in peak oil activism. This article is a draft chapter from a forthcoming book, currently titled Coal’s Future/Earth’s Fate.

With oil and natural gas prices rising and coal prices still relatively low, the return of the US to a greater reliance on coal might seem inevitable. However, several recent reports suggest that coal reserves, which have shrunk dramatically during the past century, may still be overstated. Coal prices are likely to rise precipitously during the next two decades due to transport bottlenecks and higher transport costs, falling production trends in many current producing regions, and the lack of suitable new coalfields. This information should give pause to any agency planning new coal power plants today.

The Coal Crunch is Materializing

In recent days a series of media articles surfaced pointing to a concerning situation in China. The New Scientist reported:

At the end of a cold and stormy winter, the country has just 12 days of coal reserves at most power stations. Some provinces, including Hebei, bordering Beijing, have less than a week's coal left. This is a record low, the state electricity regulatory commission revealed on Tuesday.
