A new picture is emerging in the U.S. power sector. In 2007, electricity generation from coal peaked, dropping by close to 4 percent annually between 2007 and 2011. Over the same time period, nuclear generation fell slightly, while natural gas-fired electricity grew by some 3 percent annually and hydropower by 7 percent. Meanwhile, wind-generated electricity grew by a whopping 36 percent each year. Multiple factors underlie this nascent shift in U.S. electricity production, including the global recession, increasing energy efficiency, and more economically recoverable domestic natural gas. But ultimately it is the increasing attractiveness of wind as an energy source that will drive it into prominence.

Wind power accounted for just 2.9 percent of total electricity generation in the United States in 2011. In five U.S. states, however, 10 percent or more of electricity generation came from wind. South Dakota leads the states, with wind power making up 22 percent of its electricity generation in 2011,... Read more

  • It’s time to rethink Japan’s energy future

    Nearly four weeks after a 9.0-magnitude earthquake and tsunami devastated northeastern Japan, emergency personnel are still struggling to stabilize the disabled Fukushima Daiichi nuclear power plant. Beyond the immediate need to minimize further radioactive leakage and protect public health, the government is beginning to reconsider its long-term plans for nuclear power expansion.
