About
• The Southern Wind Energy
Association (SWEA) is an industry-led
initiative that promotes responsible use
and development of wind energy in
the South.
• Our vision is for wind energy to
become a leading source of energy in
the South
• SWEA’s geographic region covers
eleven Southeastern states

Irene (2011)
“It wasn’t necessary as it turned out, but better safe than sorry — if we’d known it was going to only be Cat 1, it would have been more fun to be generating electricity.”

Tax Credit Phase-out
Adapted from Mark Bolinger, "An Analysis of the Costs, Benefits, and Implications of Different Approaches to Capturing the Value of Renewable Energy Tax Incentives", Lawrence Berkeley National Lab 2014
Utilities could lose at least $217 million on 1,000 MW of wind energy by waiting a year.
