An interesting story from MIT on the difficulties in transitioning to wind power.
It has also shown that a big state can get a substantial amount of its power from renewable sources without significant disruptions, given the right policies and the right infrastructure investments. The U.S. Department of Energy’s 2015 report “Wind Vision” set a goal of getting 35 percent of all electricity in the country from wind in 2050, up from 4.5 percent today. In Texas, at times, that number has already been exceeded: on several windy days last winter, wind power briefly supplied more than 40 percent of the state’s electricity. For wind power advocates, Texas is a model for the rest of the country.
But it also reveals what wind power can’t achieve. Overall, wind still represents less than 20 percent of the state’s generation capacity—a number that dips into the low single digits on calm, hot summer days. And even with the wind power boom, the state’s total estimated carbon emissions were the highest in the nation in 2013, the most recent year for which data is available—up 5 percent from the previous year.
