Polls consistently show a high level of environmental awareness in the U.S. However, awareness frequently does not translate into action.
The use of environmentally friendly technologies such as solar and wind power has grown modestly, except where subsidized or mandated. In part, this is because they have been more expensive than their fossil fuel using counterparts. However, even as those costs approach parity, growth rates drop significantly when subsidies are removed.
