Bending the law of diminishing returns on fuel economy

Larry Vellequette had an interesting column about diminishing returns from vehicle efficiency technologies in the July 11, 2014 Automotive News. He was commenting on the chart below showing annual... On fuel economy, what matters is the cost of adding technology compared with the fuel savings it delivers. And all the evidence points to technology costs falling fast enough to keep pace with the...

The end of the era of heavy fuel oil in maritime shipping

Since the 1960s, heavy fuel oil (HFO) has been the king of marine fuels. Viscous, dirty, yet inexpensive and widely available, HFO propelled a long period of robust growth in international shipping,... Viscous, dirty, yet cheap and widely available, HFO propelled a long period of robust growth in international shipping. But its price doesn't reflect its impacts on the environment and human health...

Let’s update US fuel policy to promote electric vehicles (Part II)

We’ve argued elsewhere (see here and here) that the U.S. should take steps to include renewable electricity for electric vehicles under the Renewable Fuel Standard (RFS). Last week, EPA took a small... Last week EPA finalized a new pathway for biogas electricity used in electric vehicles, a step that could potentially open up new avenues to incentivizing more types of low carbon fuels in...

A false choice: Carbon taxes and fuel efficiency regulations

I read Henry Paulson’s Sunday New York Times op-ed on the climate crisis and Paul Krugman’s response with interest—and frustration. Mr. Paulson called for putting a price on emissions of carbon... Fuel taxes or carbon fees affect fuel consumption in different ways than regulatory standards do. They complement each other, and we need both.
