Wind power in Indiana was limited to a few small water-pumping windmills on farms until 2008 with construction of Indiana's first utility-scale wind power facility, Goodland (phase I) with a nameplate capacity of 130 MW. As of 2012, Indiana had a total of 1543 MW of wind power capacity installed ranking it 13th among U.S. states, with more under construction or in planning. The main utility-scale development to that point had been in the northwest part of the state in Benton, White, and Jasper Counties. Fowler Ridge phase III should be completed later in 2010, to give a final nameplate capacity of 750 MW, making Fowler Ridge the Midwest's largest wind farm, and one of the largest in the world. Phases II-VI at Meadow Lake, when complete, will make Meadow Lake even larger at 1000 MW.

On February 11, 2010, the National Renewable Energy Laboratory released the first comprehensive update of the wind energy potential by state since 1993, showing that Indiana had potential to install up to 148 GW of onshore wind power nameplate capacity, generating 443 TWh annually. For comparison, Indiana consumed 106.549 TWh of electricity in 2005; the entire U.S. wind power industry was producing at an annual rate of approximately 50 TWh at the end of 2008; and Three Gorges Dam (the world's largest electricity-generating station) produced an average of 80 TWh/yr in 2008 and 2009.
Indiana also has some offshore wind resources in the shallows of Lake Michigan along its shoreline. However, offshore wind power development is far behind onshore development in the United States generally, because onshore development is cheaper and the United States has an abundance of suitable onshore sites to develop. Indiana has no offshore wind farms as of 2013.
The following table of wind farms and utility-scale wind power developments uses data from the AWEA, the State of Indiana, and other sources. For the larger projects constructed in phases, the table lists separate information for each phase. The name of each wind farm is the name used by the energy company when referring to the farm. The Wind Farm suffix is implied and hence removed for brevity. For more details and references for each wind farm, see its article.
In addition to the above wind farms, single stand-alone units have also been built in five other locations, mostly at schools. Some of these units were placed to test the environment for future wind energy development.
According to the USDOE, each 1000 MW of wind power capacity installed in Indiana will annually save 1,684 million gallons of water and eliminate 3.1 million tons of carbon dioxide emissions.
For comparison, Indiana emitted a total of 230,830,000 metric tons of carbon dioxide in 2007.
As of March 2010[update] Indiana lacked a renewable energy standard, unlike several other midwestern states: Ohio, Illinois, Michigan, Minnesota, Missouri and Iowa. Nevertheless, Indiana's wind power development had outpaced that of Ohio and Michigan.
