Comments Off on On 40th Anniversary of Arab Oil Embargo, A Chance to Master Our Own Energy Destiny

This week, the United States faces down the looming deadline for extending its debt ceiling, a line in the sand that economists say could have dire consequences for our nation’s and the world’s economy if the U.S. defaults on its credit obligations. With the federal government shut down for nearly two weeks on top of…

When President Obama unveiled his long-awaited climate change strategy this week, he never mentioned biofuels. (See “Obama Unveils Climate Strategy.”) But with nearly a third of U.S. greenhouse gas emissions due to burning petroleum for transportation, a key and controversial question is what role plant-based alternatives can play in cutting the nation’s carbon emissions. As…

Hoping for lower prices at the pump? Don’t hold your breath. Here’s why. During presidential election years, pretty much anything can become a political football. And so it‘s not surprising that with gasoline prices well above $3 a gallon, the cost of gasoline has become a topic on the stump. Mitt Romney and his fellow…

Change is hard in the world of energy, and nothing shows that more than attempts to change the deep roots of the vehicles Americans drive every day. Almost all the oil we use as a nation goes for transportation, with all the implications that brings in terms of dependence on foreign oil, gas prices that…

Natural Gas for Cars

Does it make climate sense to drive cars with natural gas? Our nation appears to be rapidly moving to a natural gas-powered economy. Advances in hydraulic fracturing (fracking) and horizontal drilling have made huge deposits of natural gas in shale and tight sands commercially viable. (See “Hydrofracturing: An Energy Revolution.”) Suddenly the United States is…

Comments Off on A Truckers’ Strike Drives Home The Depth of São Paulo’s Dependence on Cars, and on Fuel

In a city addicted to driving like São Paulo, a sudden shortage of fuel hits hard.  With a fleet of 6.6 million vehicles in January, and about 630 more hitting the streets each day, fuel was taken for granted in Brazil’s largest city and financial capital. Until one day last week, it was not. Now,…
