Looks good to me! But I suggest we test deploying to the development or staging servers on this branch first, to make sure it doesn't break deployments. And future work, update the licensing language for "Alliance for Sustainable Energy" -> "Alliance for Energy Innovation". But we'll want to confirm with our licensing team on that.
