The Arctic is melting faster than predicted. Is now the time to shut down the low-carbon nuclear power plants in France — the 20th Century’s staunchest proponent of nuclear energy? Is natural gas produced via hydraulic fracturing or ‘fracking’ a gift that is buying time for a transition to renewable energy or a curse that reinforces fossil fuel dependence? Will carbon belching heavyweights such as the U.S. and China ever get serious about cleaning up their energy systems?
Such questions are top order in France, whose President kicked off a Grand Débat on energy this month Continue reading →
Natural gas has no odor, but you can smell a leak thanks to the addition of an odorific mercaptam compound. Do carbon dioxide and other similarly odorless greenhouse gases (GHGs) require some analogous device to make their presence known and thus prompt evasive action? Yes, and for these ubiquitous gases, it will be a visual cue indicating the source and quantity of GHGs Continue reading →
In January we reported that winds across the Northern continents were losing some of their punch, and that climate change threatened to weaken them further — altogether bad news for wind power. In stark contrast, Australian researchers report today in the journal Science that gusts are accelerating over Earth’s oceans.
Unfortunately the trend offers offshore wind power a mixed bag: stronger but also more dangerous winds. “Mean wind conditions over the oceans have only marginally increased over the last 20 years. It is the extreme conditions where there has been a larger increase,” says Ian Young, vice chancellor at the Australian National University in Canberra and principal author of today’s report.

Automotive News let Lutz speak for himself, arguing that at 78 years old he was too “geriatric” for an ailing automaker in need of rejuvenation. That logic flies in the face of Whitacre’s logic that what GM needs most, after ousting two CEOs in 2009, is stability. After all, Lutz has served in top product development and marketing roles for GM since 2001, and previously held top jobs at Chrysler and Ford.
What makes Lutz the wrong man at the wrong time is that he rejects the intensifying concerns for sustainability that now drive automotive markets and innovation worldwide. At the Detroit Auto Show last week Lutz held forth on climate science with the Sydney Morning Herald, explaining that Earth is being cooled by a dearth of solar flares rather than warmed by greenhouse gases from cars and other fossil fuel-burners:
“All I ever say is look at the data, look at the empirical evidence…Katrina was six years ago and we have yet to have the next hurricane.” Continue reading →
California is about to add to its record of leadership on clean energy policy with its innovative Low-Carbon Fuel Standard that goes into effect January 1. We highlight the program and its likely impact on alternative energy sources for transportation today at MIT TechReview.com in “Low-Carbon Fuel Rules”. As the tagline states, “California is about to implement a standard to boost cleaner fuels and punish the rest.”
One point is that California’s LCFS may not deliver the knock-out blow to Canada’s carbon-intensive tarsands that many climate change activists continue to hope for. Gasoline and diesel fuel refined from the tarsands’ asphaltine bitumen may escape being banned if its producers emphasize energy efficiency according to UC Davis’ Daniel Sperling.
Another observation I’ll be following up is the cohesiveness of the biotech industry. In the face of regulatory innovations such as the LCFS that would disadvantage corn ethanol production and advantage cash-hungry innovators developing more carbon-smart advanced biofuels, the latter seem to be quietly defending the status quo.
Then there’s the California standard’s nuanced approach to diesel, which is not addressed in the TechReview piece but which Carbon-Nation spotlighted last summer. The short take is that the LCFS mandates separate and equal reductions in the carbon footprint of the gasoline and diesel fuels sold in California. That approach eliminates the possibility that diesel use will be incentivized as an alternative to gasoline. The reason? California regulators believe that even today’s ‘clean diesels’ release more than their share of soot, which is a major cause of premature mortality and also a potential contributor to climate change in its own right.
