Wind energy enjoyed a record year of installations in the US in 2012, adding 13,124 megawatts of capacity, according to the American Wind Energy Association.

That achievement, underwritten by $25 billion in private investment and supported by production tax credits which Congress renewed for 2013, means that wind was the “the number one source of new U.S. electric generating capacity,” according to the industry group. Put another way, wind provided around 42 percent of all new generating capacity, more than any other single energy source.

The top states for adding wind power in 2012 (and how much capacity they added) were:

1. Texas (1,826 MW)
2. California (1,656 MW)
3. Kansas (1,440 MW)
4. Oklahoma (1,127 MW)
5. Illinois (823 MW)
6. Iowa (814 MW)
7. Oregon (640 MW)
8. Michigan (611 MW)
9. Pennsylvania (550 MW)
10. Colorado (496 MW)

“It is a real testament to American innovation and hard work that for the first time ever a renewable energy source was number one in new capacity,” AWEA Interim CEO Rob Gramlich said.

“We are thrilled to mark this major milestone in the nation’s progress toward a cleaner energy system.”

Texas remains the leader among states with the most accumulated wind power, followed by California and Iowa.
