There is a great deal of controversy about how much uranium will be available for future use. I decided to check to see for myself, and came to the conclusion that we are likely headed for problems within the next ten years. Below the fold are a few things I discovered, in looking through reports available on the Internet.
Impact of Credit Crisis on the Energy Industry - Where Are We Now?

I recently looked through news articles to see which energy sectors were being affected by the credit crisis. I was amazed at how widespread and how devastating the impact is.
There are really two closely related problems. One is reduced access to credit, making new borrowing difficult for nearly every business that requires debt. Prices for all commodities have been dropping as well. At least part of the reason for this price decline is the lack of availability of credit—many of the less credit-worth buyers drop out of the market. This leaves fewer buyers and almost the same number of sellers, so the price drops.

In this post, I examine how reduced access to credit and the concomitant decline in commodity prices is affecting energy companies.

The Australian: ALP uranium ban is dead with Nats role in WA government
Unless there are any last-minute surprises, it seems that Labor will not have a clear majority and so the pledged legislative ban on uranium mining is a dead duck.
Both the major parties are predicting a hung parliament, with the Nationals holding the balance of power. Even if the Nats were to support a minority Labor government, their policy on uranium is firmly pro-mining. Which will no doubt be a relief to Cameco and Mitsubishi, companies that jointly just paid $495 million for the large Kintyre uranium deposit in Western Australia. The next best project, and closest to development, is Toro's Lake Way, which contains 10,835 tonnes of U3O8. The company also has the Napperby deposit in the Northern Territory.
Stuff.co.nz: Meet Australia's most frugal car
This car is poised to become Australia's most fuel-efficient vehicle. The new i20 is the car that could replace the Hyundai Getz in Australia from next year and Hyundai claims the diesel version will use just 4 litres per 100km, less than the Fiat 500 diesel (4.2L/100km) and the Toyota Prius (4.4L/100km).
The Euro-styled i20 will replace the Getz in Europe towards the end of this year but Hyundai Australia is yet to confirm whether the car will be sold down under.
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%.

Canada as an energy superpower

Ed note from PG: I am happy to announce that TOD:C is up and running again (and I believe overdue thanks are in order to Stoneleigh and Ilargi, now over at The Automatic Earth, for their efforts here). One of the new editors is benk (and I believe you already know Khebab!).
Ben is completing his Ph.D. in Chemical Engineering in Canada. His research focuses on the fine details of solid oxide fuel cells, dealing with ceramics and long equations. He attributes his initial interest in energy to the documentary "The End of Suburbia," which he first saw about 4 years ago. Since then he has felt a duty to get the good word out. Ben has been the host of theWatt Podcast talking about various energy issues, a capacity we are exploring bringing the TOD. Welcome Ben!
To get TOD Canada rolling again, I've written a refresher on Canada's energy situation. Canada can't be ignored when it comes to energy. We are a land of plenty. Lots of land, lots of weather, lots of consumption, lots of production. Plenty can easily become scarce though and it has to be managed, and managed well. Management of our resources will be Canada's challenge in the years ahead. Unmanaged, Canada's energy consumption is close to the highest in the world and stands at 350 GJ/person, slightly more than in the U.S. and Canada's energy intensity is the worst in the G7 at 10.6 MJ per unit GDP.

...not when you take into account the uranium-peak, the energy return on energy invested in the nuclear life-cycle, and the prospect of much of the legacy of nuclear waste being abandoned for ever.This is a guest article by Dr. David Fleming. Fleming is the Founder Director of the Lean Economy Connection, and an independent writer in the fields of energy, environment, economics, society and culture. The article is based on Fleming’s recent 56-page booklet, The Lean Guide to Nuclear Energy, which expands and references the arguments presented.

US Electricity Supply Vulnerabilities

We on The Oil Drum spend so much time worrying about oil supply that we tend to think that electrical supply is relatively safe in comparison. If we stop to think about the issues, I think that we will find that the electrical situation is not much better than the oil situation. The likelihood of widespread electrical outages in next five to ten years is uncomfortably high.
We may already be starting to see some beginning examples of electrical shortages, such as this recent story regarding Maine. Residents were being asked to conserve electricity because of a natural gas shortage related to supply disruption and cold weather. Maine has a relatively tight electrical supply and heavy dependence on natural gas, so it is at high risk for this type of disruption. I expect to see more outages like this in the coming months and years, especially in high-risk areas.
In this post, we will look at some areas of vulnerability for the US electrical supply. While this analysis is restricted to the United States, some of the issues discussed may also be relevant to other countries.

Warning: The Mining Boom is Fading Fast

Original Story from Monash University Faculty of Engineering: http://www.monash.edu.au/news/newsline/story/1231
A Monash University environmental engineer has warned in a new report that mineral resources are running out, excavation costs are escalating and the environmental costs of mining are devastating.

The world-first report, The Sustainability of Mining in Australia: Key Trends and Their Environmental Implications for the Future, was authored by Monash researcher and lecturer Dr Gavin Mudd in conjunction with the independent Mineral Policy Institute.
Dr Mudd said the statistics were alarming. "On average, 27 tonnes of greenhouse emissions are created to mine a tonne of uranium. That's equivalent to the annual emissions of nine family cars. To mine one kilogram of gold it takes 691,000 litres of water, and it takes 141 kilograms of cyanide to produce a single kilogram of gold.
