Commentary: Will we be able to maintain & replace our energy & transportation infrastructure in a post-peak oil world?

by

However, when we look at the global economy from the point of view of a long-term decline in global net oil exports, it seems very likely that, to paraphrase a famous quote, what can’t be funded and maintained won’t be funded and maintained; and that the funding and maintenance problem will probably continue to become most apparent in the short term in American suburbia and exurbia.

ODAC newsletter – Apr 1

The oil price firmed to around $117 this week as evidence emerged of the impact of the Libyan crisis on the oil supply. Bloomberg reported that OPEC oil output dropped in March as Saudi Arabia failed to make up the loss in production from Libya. Reuters reported that Saudi has unexpectedly called on oil companies to expand its drill count by 30%. It is not clear whether this is in an attempt to add further spare capacity, or whether the kingdom is struggling to raise production.

Fukushima Dai-ichi status and prognosis

by

The disjointed news flow from Tokyo Electric Power Company (Tepco) continues to provide a confusing picture of the status of the 4 crippled nuclear power stations at Fukushima Dai-ichi on the East coast of Japan. This is leading to a very broad spectrum of opinion on the actual status and future consequences. The spectrum of opinion ranges from those who argue that Fukushima Dai-ichi is on course to become a Chernobyl scale incident or worse, to those who argue this is a storm in a teacup pointing out that reactors have been hit by a large earthquake, gigantic tsunami and survived with minimal casualties so far. So where does the truth lie?

Artificial leaves and old Buicks

What I object to is this style of science based on press releases which are only hype and no substance. I understand that scientists are human beings and they like to be in the spotlight once in a while. I understand also that one may need to use these methods in order to get research grants. But, in the long run, this is something that only generated false hopes and disillusion.

Radiation in Japanese Food: Interview with David Waltner-Toews

by

There are so many things to consider here—the actual safety, the consumer acceptance, and what other food is available. In some countries after Chernobyl, health and environment officials simply increased the threshold for safety. The rationale was that it was better to eat some fresh foods that had a bit of radioactivity than to eat only processed, imported foods. It will take a lot of monitoring to sort through this over time.

Energy efficiency to the rescue

by

At the same time, it’s important to have a realistic understanding of efficiency’s limits. Boosting energy efficiency requires investment, and investments in energy efficiency eventually reach a point of diminishing returns. Just as there are limits to resources, there are also limits to efficiency. Efficiency can save money and lead to the development of new businesses and industries. But the potential for both savings and economic development is finite.
