Manufacturing in the U.S. still uses the most energy. But its share has been decreasing. That's partly because we've moved from energy-intensive manufacturing to a more service-based economy. And also partly because of a slowing population growth and improving energy efficiency.
The U.S. is embracing wind energy, with wind turbines making up half of the new electricity added to the power grid last year. But a smattering of people who live near the turbines say they're a nuisance — and making them ill.
The U.S. Environmental Protection Agency could soon issue a final ruling that aims to force oil companies to replace E10, gasoline mixed with 10 percent ethanol, with E15.
This move could come just as widespread support for ethanol, which is made from corn, appears to be eroding.
Mike Mitchell was once a true believer in ethanol as a homegrown solution to foreign oil imports. He owns gas stations, and he went further than most, installing expensive blender pumps that let customers choose E15, E20 and all the way up to E85.
