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.

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.

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.

Managing the 21st century’s sustainability crises (program 192)

by

“ There are no real solutions, there are only responses.” So say the expert contributors in The Post Carbon Reader, pointing to society’s complex, interdependent systems squeezed by growing demand and declining resources. Co-editor Daniel Lerch tells us renewable energy will never be able to replace fossil fuels. Thus resilience — the capacity of a system to withstand disturbance while retaining its fundamental integrity — needs to replace sustainability as a guide to action.

ODAC Newsletter – March 25

Bombing raids began on Libya this week as western powers combined to enforce the UN mandated no fly zone. The offensive has succeeded in its initial aim of slowing down Gaddafi’s forces, but the precise remit is unclear and a protracted conflict in the country is still highly likely.

New record for German renewable energy in 2010

by

As the nuclear reactor accident at the Fukushima Daiichi plant continues to dominate the world’s attention, Germany has quietly broken more renewable energy records. . . The conservative government of Chancellor Angela Merkel, struggling to stay ahead of public attitudes toward nuclear power in the run-up to regional elections, issued its annual report on the contribution of renewable energy to the German energy market in 2010. . .

Attributing the food price spike

by

All caveats aside, you can see the main point here: biofuels are much much larger than Russian weather fluctuations as a total factor affecting cereal supply for food. This is not to deny any role for the Russian harvest change in the current food price spike.  It was an unexpected negative shock, and I’m sure it was the straw that broke the camel’s back.  But should we blame the straw, or instead focus on the fact that the camel was already loaded to the breaking point?

Five lessons from a month in hell

by

On the surface, the nuclear crisis in Japan and the political crisis in Libya (along with at least five other countries in the region) might seem unrelated. But when it comes to our self interest here in the United States, there’s one thing that binds them together: our unquenchable need for energy and the price we pay for that addiction. And there are a few lessons I think would behoove us to learn from this month in hell…

After Fukushima: a new dash for gas? Really?

by

The final outcome and cost of the nuclear accident at Fukushima are yet to be determined but the obituary of the nuclear industry has already been written, and one competing source of power has already been declared the absolute winner by the Serious People: natural gas. Renewables are nice, but unSerious (not “reliable,” too expensive) so we need to rely on the big boys. Coal is a bit too dirty to be pushed openly, so gas is it. Cheap, abundant, clean and quick to be ramped up. Case closed.

Or is it? Let’s take all of these arguments in turn.
